now on bbc news, the travel show. this week on the show — going wild. can you see him in the distance? treasure hunting in lebanon. and on board a leaky boat in crocodile—infested waters. i have lots of water in my boat. i don't know exactly why yet, but here it is.

chile and patagonia, a place where tradition is meeting progression. a wild majestic spectacle where one of the world's longest countries has benefited from the largest land donation in history to create a conservation project on a vast scale. among the plans in place is an initiative hoping to bring more visitors to the area, called the route of parks, joining 17 old and new national parks together to create a huge network of wild areas to explore, more than 1,700 miles.

myjourney to its heart takes me six hours in a 4x4, along rough terrain. so, we've blown a tire, and as you can see behind me, the road is pretty rough. we've hit one of these huge potholes, and i guess that's part of the story of tourism here. the infrastructure is still a work in progress for the government, but for two philanthropists, doug and kris tompkins, the route of parks was just the latest part in a decades—long project in both chile and argentinian patagonia. doug had spent time in patagonia before, creating the clothing brand north face, and kris had been ceo of the brand patagonia.

when he decided to get out of business and do something different with his life, just dedicate his life to conservation and those things that he loved, these two countries came back into the front of his mind. in 1991, doug bought a coastal farm in southern chile, and over 30 years, along with kris and the tompkins conservation organisation, they bought 2 million acres acres across chile and argentina. rewilding came high on their agenda, repopulating the diverse range of species that had become critically imbalanced. the numbers of nandu birds in chile have dropped significantly. in this valley, rewilding has raised numbers from a dozen to around 70 so far.

so, how does the nandu fit into the ecosystem here? the changes here have brought new opportunities for locals through tourism and a range of work, including for that traditional chilean cultural icon, the gaucho.

don daniel now helps monitor the native huemul deer. traditionally, gauchos are horsemen skilled at protecting cattle and sometimes hunting predators. but now, dan daniel has a wider review of the predators as an important part of the animal network. today, don daniel uses modern techniques to track the tagged huemul deers nearby.

so, the signal's quite strong when we point the antenna that way. it's like one of those tv antennas from the �*70s or �*80s that you had on your roof. but it seems to be doing thejob. 0h, yep...i can hear it. beeping. 99% of the original huemul population are thought to have been lost, leaving them endangered. but with don daniel's help, we soon spot something in the distance. gosh, look at don daniel go! so...we�*ve actually found a huemul deer. can you see him

in the distance? he's just sitting there in the grass, and he's quite well camouflaged. we move for a closer look and quickly see that there are in fact three huemul together. so, we're approaching the deer from a lower ground angle so we don't scare them.

it's unbelievable that now the numbers have grown, and we've been able to track them within the space of a quarter of an hour, and here we are, and we're able to get this close to them. in 2017, tompkins conservation donated the last of the parks of the chilean state under the condition that they are protected as national parks. the chilean government also added to existing national parkland to create the route of parks, an area the size of switzerland. the tompkins donation was said to be the biggest private land donation to a country in world history. but it was not without controversy. i think that colonisation of territory in human history is absolutely discussed as it should be.

there's no question about that. i don't think we can roll back the clock and hope that slavery didn't happen and that...that almost the entire globe was conquered by four or five imperialist countries. there's no question about that. i'm very proud of what we do because every hectare we have ever purchased goes right back to the people of the country. tragically, doug never saw the completion of the donation, passing away in 2015. a good friend of mine from new york city wrote to me just a few days after he died, and she said, "look, you have a choice here. "you can be the long—suffering widow "or you can get out of bed and go do these things." and she was right. i had — that was a conscious decision i was going to have to make.

and so ijust thought, ok, let's go for it. and that's when i started trying to tie up everything, and within two years, we had them all donated. wow. and that was a lot of work. and i think it saved my life, needing to do that. yeah. and what would doug have said...sitting here now? 0h, he would have said... "goodjob, bird." imagine he's pretty happy, yeah. good. i'm happy. yeah. i mean, we're not done yet, but i hope we're never done. stay with us, because still to come on the travel show... the neglected

treasures of tripoli. we're with the man who's made it his mission to document these lebanese artefacts before they disappear forever. and we catch up with karolis as he attempts to make it up sri lanka's historic hamilton canal by paddle. and this time, he's in it up to his neck. so, don't go away. welcome back to patagonia here in the foot of chile, and just over there, you can see the border with argentina. and i can tell you, it gets pretty chilly down here. but let's head now to a totally different climate and a different part of the world. we're crossing to lebanon next, and to its second city, tripoli. it's not quite as well known as its big brother, beirut, to the south, but what it lacks in fame, it makes up for in public art and architecture. after hundreds of years out in the elements, its many artefacts are beginning to show signs of wear and neglect.

but one man has made it his mission to record these islamic treasures for posterity. call to prayer. the priority today of the people is not art. it's about finding medicine or finding food to sustain their daily life. despite this art is still valuable and important, now it's more important than ever because we have a huge risk of losing it. i was born in tripoli, i was raised in tripoli,

my family's also from tripoli. tripoli's everything to me. what i really like in this city, it's like a really authentic city, yet it's still working since its establishment, so it never stopped. and the people here, they are fighters and survivors. when i started really exploring this city, ijust saw how rich the city is like in art and architecture and culture and tradition. we go right, then we go left, then there is a door of an old facade of a school. then if you notice, you see a beautiful pattern just in the middle of the stairway going up. can you imagine how much work this will take, someone will design it and then someone will try to sculpt it

and to carve it into stone and then someone to come and place it here to decorate this facade and then just forget about it, easy. look at this example, by the way. you would see 700 year old patterns just covered with graffiti. they could have done it on a lot of other places, whyjust here, on top of there? and look at this two beautiful schools. you can see the history of the city literally fading away. the purpose of this project is to document and digitalise islamic art that we have in the city to preserve them for the future generations. one, two, three.

camera clicks after taking three photos from three angles, i will be importing them to this programme so i can take the mutual points and then create a photo, so i have a very sharp 2d version of the pattern itself. god forbid if anything occurs in the city, it would be a catastrophe because we would be losing the original artwork but since we documented these artworks we are able to create the exact professional version that the artist used 700 years ago. a lot of my work now reflects the history of the art of the city and working with these old materials and artistic designs, ifelt like i was part of history now. like there's something of me attached to these stone pieces.

i wish i could be positive, hoping good things for the future of lebanon and tripoli, but the problem is we are losing a lot of good minds travelling and emigrating everywhere in the world. but i hope one day tripoli would regain its power and its glory and that the people would have more time and more energy to respect art and to love the city, and maybe to see it the way i see it. explorer karolis mieliauskas is on his latest challenge, paddling 50 kilometres down sri lanka's canal network to the capital colombo. after meeting people leading

the efforts to clean the waterways, wejoin him in negombo for the next stage of his journey. this time, he's navigating a lagoon, visiting the city's largest fish market and exploring the forest that could prove a vital tool in the fight against climate change. so i am here on the canal this morning, starting my trip to the lagoon. this is actually how the water looks like. yes, you are right, it's black. i entered the lagoon just a few hundred metres away, what i expect now at least a much clearer and clean water. in the beginning it doesn't look like any better but further on, looks promising. they say the biggest fish market is here on the corner and i must visit right now.

so the biggest fish market here in negombo, they say most of the products here comes from the lagoon but some fishermen also come from the ocean. let's have a look, looks very busy. i was told that here in sri lanka fish stocks have fallen dramatically in recent years and that pollution might be part of the problem. in this fish market, recently they don't have a lot of fish because the people, they are throwing a lot of the plastic, something like that. so going out of the market, i want to see the mangroves.

i see a little waterway, mangroves. to go somewhere inside, you know? mangroves can be a very good weapon in fight against climate change. somebody said to me that during afternoon hours, some grilling proccesses are going on in the mangroves, but funny thing is, is not so easy to see something. but i can feel the nice smell of something is grilling. maybe is my lunch. what's going on? food time. food time? wow, looks amazing. prawns? from the lagoon? ok, so is the same as i saw in market today.

laughs thank you! i think it is too much for me! thank you, i appreciate it. put some lime on the fish and prawns, extremely good. this fish is amazing, and this is, i know already from yesterday is coconut with something. with lemongrass! amazing. i better go, i guess. don't want to take it too long today. 2:40pm, and these kilometres around ten kilometres probably still awaits on the lagoon and is not so easy. i was expecting lagoon to be huge, but now when i'm here, it looks like middle of nowhere. i think i have a little crack here, i don't know.

something unexpected has just happened and i have lots of water in my boat. i don't know exactly why yet but here it is. probably leaking somewhere. i discovered it's the waves spilling over into the boat. by the time i get most of the water out, night is approaching fast. still a few kilometres to go and the sun is down already. now is absolutely the time to get out from here. i can see already lights there in front of me, maybe in a couple of kilometres and this is all saints church lights. i googled already before and now i have to reach this place otherwise is maybe too dangerous to stay, there is so—called crocodiles. i haven't seen them but i don't want to feel them for sure. and is getting completely dark now so probably will not manage to reach the place

with any kind of light. i have a torch. exhales so now remains tojust keep going. and do join us next week to see if karolis makes it all the way to the end. also coming up, rajan's in dublin on the 100th birthday of one of its best—known but most challenging classic novels and meeting what have to be some of the luckiest librarians in the world. wow! look at this! the ceiling is incredible and it goes on and on for a long, long way. at must be at least 60 metres or some. and you can see more of our recent travels on the bbc iplayer. you can check us out on facebook and instagram too. just search for bbc travel show and look for that little blue logo. but until next time from all of us here in chile and patagonia, it's goodbye.

hello again. it was southern areas of both england and wales that had the best of the sunshine on tuesday, temperatures reaching 17 degrees in parts of southwest england but also around cardiff's bute park as well. wasn't like that everywhere, though. after a largely sunny start for quite a few, we had cloud tending to bubble up through the afternoon and spread across the skies, as you can see here on the satellite picture. with that cloud increasing, temperatures weren't as high for many of you. indeed around the eastern coast, just eight degrees in places. right now, we're seeing a good feed of cloud coming in still from the north sea, so predominantly cloudy weather in scotland and across eastern

areas, from northeast england all the way into parts of east anglia. but there are breaks elsewhere, notably across parts of southern england, across parts of the midlands, wales, running into northern ireland, north—west england as well. these areas, you might well start off with a little bit of morning sunshine, but even where you start off with the sun, cloud will tend to bubble up and spread across the skies in any case as we go through the day. or cloud develops later on, most of you will see quite a lot of cloud through the day. across northeast scotland, you might hold onto some sunny spells through the afternoon here. there will be one or two elsewhere in the west. temperatures about nine to 1a degrees for most. the area of high pressure has been bringing us this long spell of settled weather, still on the charts for thursday, but it is starting to weaken to a degree. we may well see just a few showers running into northern scotland, maybe one or two not far away from south—west england. 0therwise, still predominantly dry, often a lot of cloud

building through the day and temperatures not really changing a great deal, 10—15 or maybe 16 celsius. friday follows a very similar pattern as well. if you start off with the sunshine, cloud will tend to develop later on. one or two showers for northern scotland, but otherwise it's another dry day with light winds across the whole of the country. temperatures not changing a whole deal either. looking at highs potentially peaking up to 16 degrees where any sunshine breaks through the cloud. the weekend will start to see some changes in the weather as high pressure starts to relinquish its grip. a little area of low pressure could thicken the cloud up enough to bring just a few passing showers. that's most likely across northern areas of the uk, the south most likely to stay dry with a few brighter spells.
