because it was an east end group, to chingford station and then they pulled that cart up to here. of course it was almost derelict by that time. they found they couldn't sleep in the house, it was just derelict. so they had to find somewhere and that's where they found the pigsty, because it had a roof on it and it was dry. 50,000 young people had flocked to scouting during the first world war. gilwell park's priority was to replace the leaders lost during the conflict. in the years since it opened its doors, gilwell park has trained over 50,000 adult volunteers and welcomed tens of thousands of visitors from all around the world. they included members of the 23rd poplar comedy —— the east london scout troop that started that restoration work. i have learned how to pitch a tent. i have learned how to tidy up a tent.

i have learned how to cook. i am looking forward to more camping trips, because they always bring out new activities. there's like a wild forest that you can go and explore. there's lots of different activities. our last camping trip was pretty funny. because we didn't want to sleep in our tent, we would stick our heads out and look at the stars, which was pretty fun. my dear brother scout, i am 80 years old. what do you think of that? but i can't say i feel very much older than some of you. the scouting values are still there, rooted in that friendship and endeavour and going the extra mile and helping your community. and i think he'd have this huge sense of pride. nearly 80 years after robert baden powell's death, the movement he founded is thriving and gilwell is its beating heart.

well, a little earlier on bbc breakfast, robert caught up with a few of the scouts taking part in this weekend's activities. 4500 a500 explorers kites, ia—18, there they are. these guys are going to be up they are. these guys are going to be upfor2a they are. these guys are going to be up for 2a hours during continuous activity is right around the hundred acre site. they have to get to the end of that to get the certificate. alex, these are all from across the uk, but this is about more than that, isn't it? gill well park is internationally renowned. today we have a500 ia-18 internationally renowned. today we have a500 ia—18 —year—olds from england, northern ireland, scotland and wales that will have the most amazing time, loads of adventures.

they will learn skills for life at the same time, which is fantastic, really exciting. it is certainly building here. morning, guys. how many have you have been here before? who has completed the 2a? many have you have been here before? who has completed the 24? how tough was it? it was very tough. i almost fell asleep. what is the range of stuff that you get to do? there is a lot of stuff that you do. the disco was... you did it last time? yes. i survived. what is the toughest bit? just the last few hours. you have to get there but you are so tired, you have to power through it. what is so special about this place? it is a place where people can have fun and

there is no bad time! you learn new skills and spend time with friends. this is about friends isn't it? definitely. scouting wouldn't be the same without friendship, definitely. it is the first time i have been here, so i am pumped up to be here, definitely. you have no worries about getting through the 2a? definitely. you have no worries about getting through the 24? no, i have no worries. where do you come from? i'm from islington in london. so not too far. any worries about getting through all the activities? not really, no. i'm going to let you all get out. in a couple of minutes, it all starts. lets have one last look at their slots. for them, the adventure is about to start. back to

you guys in london. now it's time for a look at the weather with helen willetts. hello, they are. despite the cloudy start, some have enjoyed sun chang from the break of dawn. the sun chang will become more prevalent through the day. it will throw up some isolated heavy showers. we have seen a few showers already this morning. they are likely to turn heavyin morning. they are likely to turn heavy in the hills of scotland and the north of england. we have lost the north of england. we have lost the humidity in the south so it is more comfortable. we do have a northerly drift, which is making it feel a little bit cooler than it has been, but temperatures will get too average forjuly. the fresh start as we go into sunday morning, then a few showers will linger in southern areas. more sun chang coming through

and lighter winds away from the east coast. temperatures will do best in the west and it will feel pleasantly warm and that sunshine. hello this is bbc news with shaun ley. the headlines: scotland yard asks the media not to publish leaked government documents. the warning follows a leak which prompted the resignation of the british ambassador in washington. facebook is reportedly fined a record £a billion to settle an investigation into violations of its users' data privacy. braced for tropical storm barry. in louisiana, people are told to stay indoors as high winds and heavy flooding hit the us state. now on bbc news, it's the travel show. this week on the show... saving the great barrier reef. this is just part of the solution. we have to restore coral populations, but we also have to manage climate change.

sightseeing by sub... just started the descent under the water to the great barrier reef. ..rv adventures in the states. and a long weekend in london. our global guru's got tips for your trips. australia's great barrier reef is enormous. it's about the size of italy,

and you can see it from space. around 10% of all fish species live here. as a diver, there aren't many places that can beat it. due to increased water temperatures, there's been several mass bleaching events here on the great barrier reef, 2016 and 2017 especially. couple that with a severe tropical cyclone and up to 80% of the reef was affected. for myself, an ocean lover, it's very worrying. but there are stretches, like here on the southern part, that still thrive. schools of fish, rays, sharks and turtles are all abundant. i'm here to meet some of the people who have devoted their lives to keeping it that way. how perfect is that? billions of little tinyjewels. chromis?

yeah, blue—green chromis. they were like little swirling jewels in the ocean. it was incredible down there, rachael. wow. rachaeljones has worked in these waters for 18 months now. the marine park authorities have rewarded her efforts by giving her master reef guide status. tell me about the health of the reef we saw down there today. it's very healthy. there's just so much diversity here. up there, it's suggested 900 years old. so it's just coral that has died off and built up over time. what are some of the main threats facing the great barrier reef? we're all aware of the threats to the reef. rising sea surface temperatures, ocean acidification, we're all aware of it. but we need as many people as we can to see the great barrier reef, because they're going to fall in love with it, as you have, and then they go home and protect the great barrier reef, and all the reefs in the world. but then the more people that are coming here, there are more people flying, and therefore more carbon emissions.

isn't that bad for the reef? we need as many people as we can to see the reef, and they can choose more sustainable options. every person that visits the great barrier reef pays an environmental levy, so they are playing a part every time they come. rachael's based on heron island, about two hour's boat ride from gladstone on the queensland coast. there is a resort and a research station built on the site of an old turtle soup factory. these days, people here want their wildlife protected rather than liquidised. so, andy, exactly how big is the great barrier reef? it's immense. it's about the same surface area as germany. 2,300 kilometres in length, thousands of reefs, hundreds of islands, massive. it sounds massive. it must be hard to survey the entire thing, then. they reckon that 40% of the reef hasn't been surveyed. that much?

so from a conservation perspective, it's massive. imagine the logistics you would require to do the whole reef, it would be immense. andy is the brains behind earth hour, that 60 minutes every year when businesses and landmarks turn off their lights to raise awareness of climate change. here we are. now, though, he's turned his attention to the reef and is convinced education is the key to its survival. what i'm going to show you now is reef tracks, which is something we've already launched and is starting to show the animals that have got satellite tags that are out on the reef. wow, yeah, yeah. this is a... green turtle? yeah, green turtle, tiger sharks, whale shark. this is about to show you a whale shark. this is the first whale shark that's ever been tagged on the great barrier reef. it lost its tag after about 4,000

kilometres, but it went all the way up the reef and then out into the coral sea and then up into the solomon sea. the idea is to make people all over the world feel more attached to the reef and more fired up about protecting it. but the project he's hoping to launch next is even more ambitious, and aims to give tourists here a proper role in data collection. we call it the great reef census. the idea is to try and do a state of the reef survey in a really short period of time. so if you imagine that every tourism boat becomes a research boat for that period of time. and anybody who is a professional snorkeller, who is out on those boats, can become part of this project. so that's kind of in the water piece. but then beyond that, the citizens' science. where the citizens' science really kicks in is in the analysis. so you have the shot of a piece of reef. it's geo—tagged so you know where it is, and then you can be sitting in your bedroom in amsterdam

or your office in london, and you can be part of the analysis. it's a really ambitious project. it's not been done before like this or on this scale. save some fun for me! collecting information is one thing, but there's been a significant breakthrough this year that has seen new life brought back to dead and dying reefs. one night a year, the coral simultaneously released millions of eggs and sperm into the waters. it looks like a massive underwater snowstorm. professor harrison has set about capturing that spawn and relocating it to areas that need it most. what's the plan? 0k, what we're going to do, is i'm going to ask you to take these calipers and just go down and measure the coral. he measures the new coral regularly and has found that it's been thriving, but he's also found that after three years, it's

sexually reproductive, triggering a domino effect of regeneration. tell us a little bit about the breakthrough you've made. what we've been doing is some really exciting research. one of the innovations we've just trialled in the philippines is using an underwater robot, which we called the larvalbot. it's helping us deliver literally millions of coral larvae onto really degraded reef systems, and the really exciting news is that we've got to hectare scales, which means we can start to think about large—scale restoration using this larval technique on reefs all around the world, including the great barrier reef. this is just part of the solution. we have to restore coral populations, but we also have to manage climate change. if you're thinking about coming here, but you're afraid you might cause it further harm, here's some tips we think might help.

for most of us, a trip to australia means a very long flight, resulting in lots of carbon emissions. you can mitigate that by paying a little extra to carbon offset your flight using one of the many reputable schemes available, but also consider your flight plan. many routes will take you into sydney first, with a return shuttle to cairns. that means more time in the air, so try to find a more direct route. wear sunscreen that is considered reef safe. it should be fairly easy to find in shops once you're in australia. some of the ingredients commonly found in regular products are considered toxic to the coral. also, after you've put your sun block on, wait for at least half an hour before entering the water to stop many of the chemicals from washing straight off you, causing even more damage to the marine life. when you're in the water, watch what you're doing with your body. picking up, touching and disturbing the coral is a definite no—no, but beware also of accidental damage, particularly with your flippers.

and when you're choosing a tour operator, make sure you look for one that works in a sustainable way. look for the eco certification badges that are recognised by the marine park authority. badge holders have proven they operate to very high standards and that they go above and beyond when it comes to protecting the reef. still to come on the travel show... the reef for non—divers. how ecosphere subs can give more people a fish—eye view of the world underwater. so excited for this. can't stop smiling. so don't go away.

hello. this week i've advice on spending three days in london, a family holiday to california, and maximising mexico. first though, starting this month, new zealand is imposing an admission fee, a $35 international visitor conservation and tourism levy, which the government in wellington says will help protect the environment and pay for infrastructure. also, from october, it's bringing in an online permit for travellers who don't currently need a visa. the new zealand electronic travel authority, or nzeta, will cost $9 via an app or $12 on the website. next, christine mast gets in touch from the us to say she is planning a visit to the uk in september 2020. we'll only have three days in london, so what would you suggest we do there? i'm going to suggest that the key to your visit is getting a good geographical location right

in the heart of greater london. and that means waterloo. that should mean you can walk everywhere in the capital in hopefully the warm autumn sunshine. unlike many us cities, central london is compact, and you can plan on shopping, sightseeing, or visiting the great museums and galleries as you wish. waterloo is also ideally located for a boat trip down river to greenwich, the glorious thamesside suburb. and you can catch a train direct to windsor, a pretty english town that happens to have an enormous castle attached. tamsin bough is heading in the opposite direction, from the uk to the us, with her 11 and 16—year—old boys in tow. they are going on a family holiday to california, flying in and out of san francisco with 18 days in between. we want to explore and have a bit of a road trip.

where should we go and should we rent an rv? take state route 1 south from san francisco to los angeles. the drive along the pacific coast really is one of the world's great road trips. you can call in at monterey with its great aquarium, and also have a look at the scenery at big sur. after a couple of days in la, you can swing around and head north for death valley and yosemite national park. i'd recommend against a camper van or rv. the roads can be very tricky for what can be as large as a furniture truck. much better in my experience to rent a car and stay in budget motels, or at peer—to—peer accommodation. i suggest in yosemite national park to try camping, and in the los angeles beach—side suburb of santa monica, there is always the youth hostel for pacific coast living at midwest prices. time to head south of the border.

ronald smith wants to explore central mexico. we want to start in mexico city, travel to puebla and then on to 0axaca. is this a good plan, and is it better to use public transport rather than drive? mexico city is one of the world's outstanding capitals. to get some advice for you, i've called in an expert. puebla and 0axaca are two of the most beautiful states of mexico, so it's a great plan. the first stop must be in puebla. here are spectacular churches, colourful colonial houses and restaurants in which you can try the mole poblano, one of the most typical and old mexican dishes. four hours driving from puebla, you will find 0axaca. here you can visit hierra al agua, an incredible natural site with petrified waterfalls and views. back in the city of oaxaca, go to the temple santo domingo, eat tlayudas and drink mezcal.

rent a car, that way you can easily move from one state to another. the road that connects both states is safe and in good condition. that's all for now, but do keep sending in your travel problems and i will do my very best to find you the answers. from me, simon calder, bye for now and see you next time. for many people, diving at the great barrier reef is a trip of a lifetime. there are few places on earth you can come within touching distance of such abundant wildlife. this is heron island, just a couple of hours' boat ride from the queensland coast. scuba—diving is an amazing way to see what's hiding

underneath these waves, but if you can't scuba—dive, there are other ways you can do that too. you can snorkel, you can take a glass—bottomed boat, but there's a new kid in town. something quite exciting. this sub belongs to harvey. he's teamed up with a rideshare app and has been hiring it out for short trips. they're just getting it ready for us now. it's still not cheap though, at 3000 australian dollars for two passengers. what an incredible thing. that's just over 2000 us dollars or about £1600. this is it, the submersible. but harvey thinks this is the future. now so many more people can get underwater. you've got a tonne of people that can't for various reasons. you have a tonne of people who can't scu ba—dive. this gives people that ability to get underwater and explore and see what there is under the water. the submarine industry is still in its infancy. currently there are no other operators on this reef. many deep sea adventures in other parts of the world require you have very deep pockets. it's a small industry

but it is growing and expanding. submarines are inherently expensive, the rides are fairly expensive, but it is changing and costs are coming down, price points, things like that. aquatica is working very hard to come to market with lower cost submersibles to be able to get more of them in operation. getting into the sub. this is usually the tricky... fun and games it might be, but in the safety briefing, you are under no illusions that this is a serious piece of kit. do listen closely to the staff. do inform us of any pre—existing health conditions. do bring your camera. you've got your camera? check. i've got my camera. don't wear excessive perfume. want to smell? you smell great, we're good to go. don't bring any matches or lighters. no. don't drink lots of fluids before you dive. no bathrooms! there is no toilet! ok, i think we're good then. if you wouldn't mind hopping on the scale for me. guess my weight. i'm going to say 86. 85! dude! not bad. you win the prize. there you go, so if you wouldn't

mind hopping on here. this is for trimming the submarine, we weigh all passengers, kind of like a helicopter ride. 86! i knew it. it's a tight squeeze in the three—man sub. it's actually a repurposed research vehicle and after these tourist trips it's off to the british virgin islands to survey some of the damage left by hurricane irma. all right, are you ready to go down? i am ready to go down! here we go. we have just started the descent under the water to the great barrier reef. look at this. the water is slowly coming up and about to engulf us. ifeel a little bit nervous. once you're fully submerged i have a feeling you're going to completely forget. wow.

the sub can dive to a maximum depth of 125 metres. we're just a few metres under the surface but there's still great marine life at these depths. here we have some chromis in the front, the little blue ones. in the coral. yeah, i believe those are chromis. and we have scissor tailed sergeants or something like that, the striped ones? golden damsel, those are the yellow guys. you're good at this game. i'm getting really good. i got a chi chi. this is incredible. i can see how if you were a bit scared to scu ba—dive, or maybe you have claustrophobia... i was thinking it was going to be much more claustrophobic, but it's not. the acrylicjust opens it right up. topside, please advise us when the dive boat has passed. 0ver. can you tell us a bit about how this is powered?

the submarine is fully electric. we have a 2a0 volt dc electrical system, electric thrusters powered by batteries. and that's about it, it's very simple. so no emissions? no, no emissions, no gas, no oil, no diesel, no nothing. it's incredibly environmentally safe. nothing to leak into the ocean, battery powered, and we could charge her up and away we go. we all know the coral is quite fragile. is there any issue in bringing something so big down under the water? not at all. as you can see, she has tremendous control of the sub. buoyancy control and whatnot and manipulation with the thrusters. she can park it anywhere you want, can keep it nice and high off the reef and with the view you have, all travelling around, it works out very well and incredibly in control. do you want to try it? can i drive it? yeah. i mightjust grab it back if things go a little bit... wow, 0k. just hold it level. i'lljust do the vertical for you, you're just going to drive.

why don't you take us a little bit closer. soido... just forward. this is forward? yeah. whoa! just don't touch those ones. i'll do a little bit back, not too much. you don't want to run into the reef. that's a bad idea. i'm not qualified for this. actually, it's very much like a playstation controller, like a video game. copy that. perfect. 0ver. we are right in line with the jetty. we have made our whole round trip so we will pop up to the surface and head back to the dock. and it's all over. that was fun, though. some say we know more about the surface of the moon than we do the bottom of the ocean. what an opportunity this is to glimpse a world that so few people get a chance to see.

the sun is setting here on our time over the reef. for more from this wonderful but fragile environment check out our website or explore some of the stories we have brought you from here in greater detail. coming up next week... roger is in florida as the kennedy space centre marked its 50th anniversary of those very first moon landings. anne looks ahead to being a hub for the space tourists of the future. in the meantime, make sure to check us out on social media. we're on all the regular channels. just search bbc travel show to tag us in your photos and videos from around the world. until then, enjoy exploring and we'll catch you next time. bye— bye.

hello, they are. despite the cloudy start, some have enjoyed sunshine from the break of dawn. the sun chang will become more prevalent throughout the day. it will brew up some heavy showers. we have seen a few drizzly showers already this morning and they are likely to turn heavy across the hills of scotland, northern england, then they will drift away way southwards through the afternoon. it will feel warm for us. the afternoon. it will feel warm for us. we have lost the humidity. there isa us. we have lost the humidity. there is a northerly drift, making it feel a little bit cooler than it has been. temperatures will get to average forjuly. a fresh start for sunday morning. then a few showers will linger in southern areas, but

there will be fewer showers till tomorrow, sun chang coming through. temperatures will do best in the west. it will feel pleasantly warm in that sunshine. this is bbc news, i'm shaun ley. the headlines at 11: scotland yard asks the media not to publish leaked government documents. the warning follows a leak which prompted the resignation of the british ambassador in washington. facebook is reportedly fined a record £a billion to settle an investigation into violations of its users' data privacy. braced for tropical storm barry. in louisiana, people are told to stay indoors as high winds and heavy flooding hit the us state. at wimbledon, serena williams is chasing her 2ath grand slam title — she faces simona halep in the final today. and in half an hour, correspondents posted to london look at the week's events in dateline.
