hello and welcome to the travel show. this week, we are taking a breakfrom being on the road to look back at some of our favourite stories from the past three months. now, this summer has seen record temperatures here in london and in other parts of the world. some airlines and airports struggled to cope with so many of us wanting to travel again and sometimes, it does seem the price ofjust about everything has gone up. but that has not stopped us from bringing you some of the best travel stories from around the world. and we've beenjoined by new member the team, too! how do i have so much stuff? how am i gonna fit all of this in that tiny little car?

back injuly, we welcomed top travel vlogger ava zu beck to the team and we spent no time sending her to mexico to find out more about a simple but effective way of cleaning up the country's waterways with the help of tourists. this week, i'm in the ancient wetlands of xochimilco in the south of mexico city — a unesco world heritage site and one of the country's must—see destinations. this sprawling network of canals was first built by the aztecs and stretches over 180 kilometres. not surprisingly, the area now attracts masses of tourists every year. check out all these amazing boats. they're so colourful. these are called trajineras. i'm here to meet carlos diaz, one of the best tour good to you!

i was honestly expecting to go on a quiet little boat ride but this place is a real fiesta. oh, look, there's a mariachi! yeah.

woo—hoo! away from the joyful chaos, i want to talk to carlos how important is tourism to xochimilco? how has the area changed in that time?

professor rodriguez—vasquez has been monitoring this pollution, and it is pretty plain to see why this situation is getting worse. this isn't the most beautiful spot in mexico city, is it? yeah. can you tell me exactly just how badly the water is contaminated here? well, it's very highly contaminated with pathogens, chemicals, pesticides, hormones and human waste also. wow! yeah, and here we have a lot of places like this. so, this is not the only drain like this in mexico city. no, no, no — we have a lot. wow! not only does this pollution contaminate the water

but the dangerous pathogens can also evaporate into the air and be absorbed into the crops that are grown in the wetlands. you know, the moment you leave behind the super busy embarcaderos of xochimilco, it feels like you enter a completely different world. there's so much wildlife here, so much greenery, it's just so serene. luckily, my friend professor rodriguez—vasquez mayjust have identified a simple but effective solution. in a rather basic looking laboratory in the wetlands, her team have invented a system that produces tiny bubbles, called nano bubbles, that can be pumped into the polluted water. how does the science behind this actually work? yeah, we create the nano bubbles with solar energy,

so these nano bubbles can destroy the contaminants. as well as tackling the pollution, the nano bubbles also help to oxygenate the water, breathing life again into the waterways. and what's even more encouraging is that this simple but effective technology can be used on the boats, in the fight against pollution. but the button that started all? yes. it's working! it is so cool. it's amazing to think that this piece of tech is cleaning the canals we agsz�*; these the �*is

' i is with 7 �* is with a hopefully show is that with a lie, hopefully show is that with a bit of tourists can play a key role in helping to maintain stunning places like this, and new member ava zu beck there, reporting from mexico. as i was saying before, summer 2022 was one of the hottest on record across many parts of europe and spain and france were just two countries that saw devastating forest fires break out as a result. none of them, though, was as widespread as those that affected the greek island of evia in july 2021 and a year on, we sent our reporter to find out how it has been recovering. i have been sent some pictures of the place we are on the way

to now and it looks lovely — looks really lush and green and fertile. but i have been told that since the fires have hit this whole area, it now looks very different. and even looking at the window — look at that. just as far as the eye can see, all you can — all you are looking at is burnt trees. it is really sad. andrea and pantelis work for trekking hellas in evia. they used to take tourists on hikes through these once—stunning forests. and it looks like our path is blocked. i don't think we've got any more routes. i mean, that is astonishing. i remember seeing it from the television, from the news. i remember watching it on the tv.

i was feeling like it was fake news. i couldn't realise this is really happening. i was thinking, "it can't be true!" how much of this area was damaged by the fire? well, in numbers, it was 500,000 hectares. you can consider it as even bigger than the city of athens. so, an area larger than the city of athens? yes. was burnt by the fires? yep. i mean, even teams of firefighters from other countries had to come here to support us, bringing planes, helicopters, trucks in order to try to stop the fire. my next stop on the island is an animal sanctuary. before the fires, it was home to horses and donkeys and children could visit for riding lessons. look at these guys, wow!

something so exhilarating and majestic about watching horses run. i had a chance to see the extent of the damage the fires have had on the land here in this area. on the lives around here. what was like before fire? it was a paradise. it was calm. it was a forest — it used to be a forest, with so many trees, green. i can see in your eyes, you know, how emotional it is and it must have been a really difficult time. what was it like when the fires were raging here and what did you do? we knew the other villages was completely burnt, so we knew that — we just say — we look at the place for the last time and we went. we go.

i was thinking, "i am gonna get out alive," because everyone was leaving by car and we were on foot with six horses and two donkeys. as the fires raged through the night, the animals broke loose and ran away. we lost them. you lost them? yes. because we were just four people — us two and two friends that came for help — and the others escaped. when it was finally safe to come back, it was with a heavy heart. it was really difficult to come inside this place because all the trees was burnt and down. so there was no entrance, nothing. but they were here, all together. they went away to survive from the fire and then, they came back here and theyjust... waiting. when you are so unhappy,

suddenly, you are happy. so, they are alive, we are alive. ade in evia injuly, a year on from those truly devastating forest fires. now, stay with us because still to come on the travel show, we're looking for ancient roman ruins on spain's mediterranean beaches. i can't believe i'm holding in my hand a piece ofjewellery from thousands of years ago. that is amazing. and playing mahjong in hong kong. this is... oh, my gosh! so many rules!

the huge sand dunes of southern spain are some of the largest in europe and yet, they remain relatively unknown, even amongst the most well—explored travellers, with even fewer people aware of the treasures concealed beneath their moving sands. i'm meeting eddi pitcher, a writer and traveljournalist who specialises in uncovering hidden places, and she's going to guide me off the beaten track on my mission to learn more about the living sand dunes of southern spain. eddi, where are you taking me today? so, we are taking the wild way to the bolonia beach, and we can see that this is the way because we've got knotted — knotted beach grass here. there are no signs, so it's — i said it was a wild way. i'm definitely glad that eddi's here to show me the way on this one. wow! look at this! there you go, so you've got

your desert dune just there. wow! this is the bolonia sand dune, one of spain's largest sand dunes, standing at over 30 metres high and 200m wide, all concealed within the estrecho nature park, one of cadiz�*s most unspoilt and off—the—beaten—track areas. we made it! we did it! probably the best way to think about this coastline, which is endlessly shifting down the centuries, is as a living sand dune. and now, with climate change, the winds are getting stronger and pushing with them these dunes. so, they're really moving? yeah, exactly. these dunes are being battered by hurricane—force winds, forcing them inland and revealing some remarkable hidden history concealed below. if you think about it in terms of history, this is a melting pot of cultures. you've got africa, you've got europe, you've got all of the mediterranean and then, the travels across the atlantic, and all of those peoples have left their vestiges, their archaeological sites along this coastline,

which have been kept perfectly intact down the millennia. my next stop is cape trafalgar, 60 kilometres down the coast from bolonia, where archaeologists from the university of cadiz have just discovered some remarkable ruins, thanks to these moving sands. so, when you discovered and realised it was a tomb, you must�*ve been preparing to find some bones in here, right? so, the excavation here is very similar to the excavation in egypt tombs and they have preserved very well the bones, so the state of preservation of the tomb, of the bones is excellent. we have found arrowhead. speaks spanish. pendant. she gasps. i can't believe i'm holding

in my hand a piece ofjewellery from thousands of years ago. that is amazing. speaks spanish. a bead! christa uncovering the past there in spain. injune, carmen was also discovering some secrets in hong kong. not ancient ruins this time, but clues as to how to win the game of mahjong.

that traditional chinese test of skill and cunning, but one time looked in danger of disappearing because young people there seem more interested in gazing at their smartphones rather than outwitting their opponents at the mahjong table. as carmen found out, the game is now enjoying something of a resurgence, so we sent her to pick up some tips. some say the game of mahjong was invented by confucius himself. others, by chinese fishermen around 1,000 years ago. whatever its roots, it is massive in hong kong. it's pretty serious business which is why am trying to keep my voice down. but if you can watch a game in progress, it's a great way of getting under the skin of the city. the basics are actually very simple. the winner is the first to collect four sets of three and a pair. but it still takes a bit of figuring out.

i get confused with the win. it's very difficult if you don't speak cantonese. it's a very traditional game played largely by older people. take auntie mei here. it's claimed, she is the last female mahjong carver in the city. each tile is handmade. but there are young people here

who still care about the game and are keen to teach newcomers the rules. 0nly take from your left for sequence. yes, because this is... oh, my gosh, there are so many rules! why have i only got ten? because you have three here. maths isn't my forte. so i don't want this eight circle so your turn. i'm really not sure i'm doing this right. do you want this? i don't know, i am thinking about it. no, you can't. this is the mahjong hostel, run by iris, who isn't only a lively host, she is also a very patient teacher. because many people don't know the game until they come here, and i know many hostels do board game nights or card game nights but we like using mahjong to play with the people

because it's hard to learn at the beginning, but when you know how to play the game it's fun, and you are addicted, you want to play every night! sometimes people play until very late. you are the youngest person i've seen on this trip playing mahjong. why don't many young people get into it? people more like playing video games on the phone. everyone has their phone, they play their games on the phone. in hong kong we have a problem of lack of space. you need to set up the mahjong table, get four people together and play. it's not easy hong kong because everyone has a small house. it's not the most accessible part of hong kong culture, especially for casual tourists. the rules are complicated and most parlours here aren't that welcoming to newcomers. but there are places that'll teach you, like this hostel. surprisingly, i'm finding it really fun. that's all for this time

butjoin us next week when we have something very special for you. coming up on next week's programme, christa heads to a window corner of the straits of gibraltar. to find out why the spanish town of tarifa has become the best place to kite surf in europe. oh, my god, that was so good! i loved it. you did really well! i loved it. it really felt like being a kid again. and you're not gonna want to miss that, let me assure you. in the meantime, don't forget to follow us on social media. thanks for watching

and goodbye. hello there, we had a real mixture of weather around on thursday. it was pleasantly warm across south—eastern areas. temperatures in hampshire and cambridgeshire reached 21 celsius, 70 fahrenheit. temperatures are going to be dropping over the next few days. it looks like it's going to turn particularly cold at night—time.

we have the cooler air moving down from the north—west, it follows this band of cloud here that brought a lot of rain into cumbria. that rain is now sliding its way down towards the south—east and east anglia where we start the day with some rain. elsewhere, further north, clearer skies means it's going to be a much colder start here, particularly in eastern scotland and north east england where we will start with some sunshine. it looks like it's going to be quite a cloudy day across east anglia and the south—east, some rain from time to time. it should cheer up in the midlands and much of england and wales away from the south—east will be dry with some sunshine, scattering of showers come in on the north—westerly breeze to scotland and northern ireland. and temperatures may struggle to around 15 to 16 degrees. still sitting at 18 or 19 though with that cloudy damp weather towards the south east on that weather front there, which is only very slowly moving away. around this area of high pressure, we're going to drawn down that northerly breeze bringing in that cooler air and may be bringing in a scattering of showers this time on saturday for central and eastern parts of england. further west likely to be drier and it should be a dry day with some decent amount of sunshine for scotland and northern ireland. still the threat of a little rain in the far south—east

of england but should be moving away and typical temperatures will be around 16 degrees or so on saturday afternoon. saturday night though could be quite cold around this area of high pressure. we've got that chilly air, never really establishes itself because this is going to be quite a feature of the weather as we head through the latter part of the weekend and into the start of next week. a lot of dry weather to come on sunday but with that approaching deep low in scotland and northern ireland, the winds will be picking up and in the northwest we'll see some outbreaks of rain, sunny spells elsewhere, mind you. still on the cool side after quite a cold start, the temperatures around 15 or 16 degrees. i showed you that deep area of low pressure on the weather front that's going to be sliding southwards overnight and on monday it'll bring a spell of rain. but following on from that, we'll find the winds turning to distinctly a chilly direction and a much stronger northerly wind will drop the temperatures early next week.
