of rainfall within a short space of time for some of us tomorrow. west is best as far as those sunny spells are concerned with top temperatures reaching 20 or 21 celsius. brightening up as we head to the start of this coming week.

hello, this is bbc news. the headlines... worries over the soaring price of gas. the british government's holding urgent talks with energy industry bosses it is one of those hidden things that has immense repercussions right the way through the sector, and i really do think this is a crisis. france is recalling its ambassadors to australia and the united states, in protest over a security deal which also includes the uk. holiday firms say they expect a surge in bookings after travel restrictions in england are relaxed.

this is what we have been waiting for a long time, it takes away all the confusion, and that has been one of our biggest barriers and one of the biggest reasons why people haven't been wanting to book. us armed forces apologise for their �*tragic mistake�* after killing ten innocent people including children in a drone strike during their final days in afghanistan. for viewers in the uk, strictly come dancing is back— and there's controversy as a newspaper report suggests that two of the show�*s professional dancers are refusing to get covid jabs. now on bbc news, it's the travel show. this week, on the travel show... i am in argentina, exploring an amazing sunken town that has re—emerged from under the water. then, i had to the country's spectacular iguazu falls. and in wales, wejoin a couple

starting out on a pedal powered adventure at sea, searching for a more sustainable future. we're kicking off this week in south america. argentina, to be precise, where early last year i went to explore one of the strangest places i had ever heard of. a town that had to be abandoned due to flooding back in the 1990s, but has since re—emerged from beneath the water. you can find ghost towns all over

the world and there's many different reasons why they could be abandoned but i've heard epecuen is special, because it is not abandoned, at not completely. there's not much left... just some bricks. you can only guess what they used to be. this place is wild. there is a couple of tourists here, notjust us, but more cows than tourists. epecuen was built in the 19205, and at its peak was home to about 5000 people. tourists came from all over argentina to take a therapeutic dip

and its famous thermal bath. today, remains of her hometown, explaining what happened here. how did it become abandoned? how did it come to this?

in 1985, heavy rain and storms sealed epecuen�*s fate. a nearby dam ruptured and within weeks the town was flooded. for years and years, the water continued to rise, and by the early 90s, everything you see here was completely submerged. then just over a decade ago, the waters began to subside. now tourists can walk the streets once again. this looks damaged, but it's not, it's completely encrusted

in mineral salts from the water. the inside, not so great... i guess that's what a quarter of a century underwater does? for me, ijust see concrete, but you, you have memories here. but even when it was mostly underwater, it wasn't entirely abandoned. for over 25 years, a local legend called pablo novak lived on the outskirts.

some recent health complications have meant that pablo has had to move out of his home and into a nearby nursing facility. that means epecuen�*s last resident has finally moved away, but pablo's memories of the town still live on. while epecuen may now be fully abandoned, what is left behind is a uniquely desolate, stunning landscape with a legacy that will never be forgotten. next, we are off to new zealand to visit the north island's largest ra i nfo rest.

back in 2014, the government returned ownership of the land back to the local indigenous people who were now encouraging tourists to learn to interact with the forest on a spiritual level, rather thanjust think of it is a great place to take a hike and some photos. this tribe, my tribe here, fought for 150 years to have land returned to the people, and they were eventually successful in 2014. what was formerly the national park area became a living entity of its own with all the rights of personhood. and i believe that it was the first of its kind in the world.

they don't take over and control, they understand where they fit in, and are guided by nature. this tree, it is supporting me, and the energy from it feels mail. —— fuels. it's a few hundred years old, whatevertree, plant, that your eyes alight upon, there is that thing acknowledging you and saying hello. if you ignore them, itjust means that you need more time, so more time spent in nature, the more you tune in, the better you develop your understanding of the language that she is speaking to you.

people that i met when it was a national park often did not know much about our tribe. 0r our indigenous ancestry, children of the mist. the retreat was born out of the desire to have a place where people could stay in nature, enfolded in nature, where they could connect with nature and themselves. you are unplugged from the distractions of life. i want people to realise that you don't need much to enjoy life, and to live.

staying here strips back and takes you right back to the basics of what you need, what the body needs, what the spirit needs. still to come on the travel show... i get to experience the spectacle and sheer force of nature of the amazing iguazu falls here in argentina. and we meet the couple setting out on a sustainable journey at sea with the help of a little pedal power.

don't go away. this isn'tjust one waterfall, it's hundreds. it's three times wider than niagara and it's a marble of nature are right on the border between argentina and brazil, and i wanted to see this water for my entire life. —— marvel. water for my entire life. during the rainy season, every second, up to 13 million litres of water spill over a series of precipices stretching 1.5 miles wide. the first time that i saw the waterfalls i cried. the falls are steeped in local legends. some are more sinister than others. they believe that behind

the waterfalls, especially behind the devil's throat, there is a giant snake living there, and they have a lot of respect for that. have you seen a giant snake? never, but i have seen this waterfall and i have a lot of respect for that. it is one of the most spectacular sections of the falls, where a major portion of the iguazu river tumbles over, causing an effect similar to an ocean plunging into anna —— an abyss. wow! i've never seen anything like this before. 0ne waterfall, two, three, four, five, six, 20, 30, 100, all cascading down. the rush coming off this waterfall... you can feel it on your face and hands, this is an incredible moderate nature. —— wonder of nature.

you have to come and see this sometime in your life. wow! next, we join the husband—and—wife team on an incredible zero carbon adventure around wales, and so far they have completed almost 400 miles over hills and valleys under their own steam. now, it's time for them to tackle the spectacular and sometimes precarious welsh coastline in a boat powered just by pedal. we are on a circumnavigation of wales using just human power, so we're biking, walking, canoeing, pack rafting and using a specially designed pedal powered boat. this is an eight metre by 1.5 metre boat made out of wood,

it was designed and built back in the early 90s to complete the first circumnavigation of the planet by human power which is what i did, started off with a friend, and she is like almost a part of me, she is part of my soul now, i've spent so much of my life and her. like i'm ever gonna wear this. i think for me, human power means being able to be more part of a community, and i think one of the most special things about ourjourney so far is the fact that we are going very slowly, we are meeting some amazing people that we would have ever met. —— never met. some of the most engaging encounters in terms of people and leading onto sustainability stories which is what we are interested in exploring here in wales have come about because of human power. so we biked from greenfield dock, then we hiked over the black

mountains, used pack rafts down the river to monmouth and then we just biked from monmouth to here, milford haven. so tomorrow we are going to be peddling moksha, our little boat out into the channel essentially, around the temperature headlands and then around to fishguard, up cardigan bay, around by anglesey and back to where we started from, from greenfield dock. —— pembrokeshire headland. thank you! i can't deny that i am more apprehensive about this than crossing an ocean, which i have done in that pedal boat, several times, but this, going around the coast, you've got tides, wind, other vessels, there are so many other variables and that is what i am most nervous about.

seems pretty rough. i'm very nervous, because when he gets nervous, it really does freak me out. oh, my god! whirlpools. 0k, can you see me? no, up, up! no, up! stop!

yeah, i'm just shattered. absolutely shattered. i'm not in my comfort zone on the water, but honestly for me, it's telling the stories of the local heroes that are championing, you know, their local environments and the seals and the whales and they are out there and they are in the trenches every day working hard and they are fighting bureaucracy and i am so excited to bring those stories to other people so that they can get help, and i'm really, really excited about that. we have heard about this amazing organisation called the sea watch foundation, and jason and they are super excited, we're going to get out on the boat to see if we can't find

some dolphins and other sea life, so we are looking forward to it. what exactly is it that the sea watch foundation does? so, the sea watch foundation - is a nation wide research charity, we study whales, dolphins and porpoises in the uk. l 0ur flagship project is the one that my lead and we study - the population of bottlenose dolphins that we get around | here and we look at how do - they use their habitat and how many animals are here year after year. so today we are not actually on a surveying boat, we are on a tourism boat? yes. can you explain, is that a problem for the dolphins? it is a difficult situation. when we look at northern cardigan bay where there is actually-

a lot less tourist boats, | we have seen an impact of disturbance and that is mainly from recreational boat traffic - and we have seen an effect on the social structure - of the dolphins has not been so down here we have much smaller pods - with longer lasting bonds, . whereas up north the animals are often in bigger groups- but they have less long lasting bonds with each other. you just can't get away from it, can you? can we park on the flat part of the ocean from now on? this sounds ridiculous, but if i threw up and something eats a it...

i've had a ibuprofen and stuff today. so sick... it's like being inside a washing machine. so how was your night? it was ok... well, as soon as we get under way, it will be not this continual rlling.

honestly, we make a good team, and it's funny because we fight about little things that you know, i think we can't even remember what we thought about. yeah, we do fight but weirdly enough when we are out at sea or if we are on this expedition together... if we think we're gonna die, we're fine! can't one thing be easy! just one! i suppose when the chips are down and things are going really badly, that is when we come together and work really well together. you're welcome. tammy's cafe at sea. food weight is a huge problem. —— food waste. 80% of our food in this country is wasted so we're gonna go and find

out how this local group is preventing food from going to landfill, so they pick up food from restaurants, from people's houses and a lot of it has not gone off, it's just gone past the best before date so they make delicious food and we are tired of eating brown food on the boat, thid will be great, eating food other than our own cooking. it's reallyjust a great concept because they are feeding their local community and then anything that they can't use actually goes into a compost bin, so it is literally a complete circular economy with food that would be otherwise wasted. that's delicious! well, that's all for this week. but coming up next week: what we are trying to do here is get around this headland before the tide turns against us, but it looks like the tide has already turned.

we are back with tammy and jason as they continue their voyage but with the weather closing in, will they get to their final port of call or have to abandon their mission? you are not going to want to miss at. but from me and the rest of the team here, in argentina, it's goodbye. hello, everyone. i hope you're doing all right. there is a bit of a split this weekend, weather—wise. today, for many, plenty of dry weather and some sunshine as well. there are some showers around and some patchy rain, however. tomorrow, some of us seeing a very different thing, we

will see heavy outbreaks of rain, but equally a bit of an east—west split tomorrow, more detail on that in just a moment. this is how it is looking today. we have this week weather front draped across the uk, that is introducing cloud and rain as well. here it is on the close—up view. just drifting into eastern parts of scotland, slowly moving out of here and then into the north of england, wrapping around western parts of wales, down towards the south—west of england. much of scotland should be dry, take a bit of a tour. to the west, breezy, patchy rain, moving into parts of northern ireland later as well. sunny spells here, there is that weatherfront, introducing showery spells of rain, then across western fringes of wales, towards the south—west of england. either side of this, we should see plenty of dry weather, a few isolated showers here or there. some mist and fog this morning, that will continue to clear as we head through the day. cooler to the north, 15—16 celsius across parts of scotland, and northern ireland. the best of those

temperatures across south—eastern parts of england, 22—23 celsius. moving on through this evening, the weather front remains with us, it will pepper, so the rain will turn heavier as we head through tonight, and you can see very slowly it is creeping towards the east. we will see the return of some mist and fog patches through this evening, but then tomorrow heavy spells of rain develop, the east—west split i mentioned earlier, you can see it here, so west is best tomorrow. not completely dry, however, we will see some showers, whereas eastern parts of england and scotland will see heavy spells of rain. tomorrow's top temperatures about 20 celsius. as we look towards the coming week, we have this ridge of high pressure building, not a completely dry story on monday however, and we will see some cloud around. but more in the way of that brightness most certainly. turning windy across western parts of scotland, some cloud, patchy spells of rain as well on monday,

top temperatures about 20 celsius. as we look towards the middle and the end of this coming week, low pressure moves in, turning less settled, we will keep you posted. that is the forecast, see you soon.
