"My name is Bear Grylls. climbed to the summit of Everest and crossed the icy seas of the Arctic." "I go to one of the volcanoes more active in the world." "The Kilauea in Hawaii." "Millions come to see the lava and every year fifty lost." "I'll show you how to survive." "I'm in the middle of the Pacific Ocean going to an island in Hawaii where Mount Kilauea has been active since 1983." "Every year 2 million people come see these lava fascinated with the brightness of the magma." "But it is easy to get lost or hurt." "this sterile environment and dangerous." "I put myself in position a tourist lost here to show you how to survive." "a knife and a flint." "In a few minutes the pilot will leave me in the volcano" "We are in mid-afternoon and in a few hours goes dark." "A film crew will accompany me." "The land down there is very unstable to land so I'm down by a rope." "I'm about to dock an inactive crater slopes highest volcano." "Look at this." "It's so intimidating." "This volcano is incredibly dangerous." "A few meters below me is a lava lake temperatures above 1000 degrees celsius while the soil release a strong odor of volcanic gases." "I find a way out of here and return to civilization." "But what will the best way?" "I'll put on the crater to guide me." "Just look at this." "It's like landed on the surface of an alien planet." "The landscape is arid and deeply threatening." "It is easy to see why people get lost here." "It's just miles and km of land with nothing." "I can already tell this will be a nightmare around here." "If you get lost here try to find a path to the sea since it is near the sea most Hawaiians live." "What I know is that this volcano lies to the south of the island and that the best hypothesis find civilization is to go toward the sea." "the shore area nearest is in the south." "I will use the sun as a compass." "It is late afternoon and the sun is to the west means that South be here." "The island has more or less 130 km length and width which means that the sea should not be more than 65 km." "But this unstable ground floor is incredibly difficult." "the majority of accidents happen because people slip or fall." "If you slip here can easily break a leg." "one tourist died here gave eventually fall into the ocean." "Even for the more experienced can take an hour just to go 1 km." "Sulfur is generated by volcanoes and here is extremely thick." "Look here." "You can see the sulfur out of these holes." "And this is a sign that I on top of a lava flow." "At about one meter under me." "Volcanologists measure these gas emissions trying to see if a volcano will erupt." "I have to go." "This sulfur have an intense smell even and getting very unpleasant." "It has an intense bitter taste and entering in my throat." "And it is not pleasant." "this gas can kill." "Few years ago a helicopter crash for 3 days." "Only survived because used the shirts as masks." "that's what I'll do." "I can hardly breathe." "This is difficult." "full of that thing absolutely horrible." "but from here the air seems much cleaner." "But I need a few minutes to catch his breath." "I have already exceeded the sulfur but the gases are a sign that the lava is near the surface." "This whole area is getting now extremely hot." "And I'm always watching Small cracks going toward the lava lake here below." "In these holes in surface give the name of "skylights"." "are lava circulating tunnels known as "lava tubes"." "The temperature down there is around 1000 degrees." "If the thin crust cede would be incinerated in seconds." "But there is a circumvent an area like this and that is how it's done." "Very light test with the boots and if the boot melt say that is too hot so we can go through." "I'll now try to cross." "But the film crew will be here waiting if we tried together the crust would probably give." "Here we go." "My boots started to melt." "It's too hot." "What we see is if the rock begins to soften and if that happens and our feet start to sink we must go back and try to work around." "I managed to pass." "This rock is is less hot." "after that." "I already went through the hottest part the lava field." "But I still have to find food and water." "the only question is where." "The temperature of the volcano is overwhelming." "Dehydration is a great danger tourists lost these lava fields ruthless." "without having something to drink." "'m Getting a little worried." "I'm already running out of water." "I know we spend three days without it I have difficulty endure in one day." "The volcano receives about 300 cm of rain per year." "But the lava is so powerful most end up dry and the little water that is surface quickly evaporates in heat over 30 degrees." "Most of the rain that falls with the active crater of the volcano become contaminated with the sulfur gases transforming it in acid rain." "very few plants grow." "Once I move away the volcano crater begin to see more more plants." "The lava fields of Kilauea were once covered by a lush forest stays here." "These here are called "kapuka." "They range from small areas vegetation up huge areas of jungle." "But is there that I will have better chances find food and water." "One of the difficulties all this volcanic area is that there are rivers or streams or lakes." "But the best chance find water will be here in the jungle or a hole or a cave." "But it will be difficult to find whatever this vegetation so dense." "Look at this." "Look." "Avocados." "And this is an avocado." "And this is good news for me." "I love avocados." "I'll see if I can catch some." "Avocados grow on topmost branches of the tree protect fruit possible predators." "I can use some of these vines to get up there." "just a little longer." "And this is what I want." "I'm so hungry I'll eat them right here." "I will not wait until fall." "I'm trying to position to take the knife." "Now just take this bark." "Avocados are one best foods nature." "protein and good fat." "This is wonderful." "I just love avocados." "If ever ..." "were lost on a desert island this would be one of the things I would take with me." "and mayonnaise   and chocolate." "it's time to go." "I'm going toward the coast because that's where you find people." "I want to get there as soon as possible." "Not want to spend the night in this jungle." "This was a gift." "I will save one for later." "But have not found water." "this volcano before being rescued." "He kept himself alive by sucking water bits of moss." "But what I want is water." "The water of a lake be stagnant water." "And stagnant water is the ideal place for bacteria or may be contaminated by animal feces." "Until I see something I can lead to safe drinking water." "Look at this." "This is an old lava tube." "the lava went through this area on their journey to the sea." "Hawaii is full of ancient lava tubes." "Tunnels that once transported the lava of the volcano to the sea." "For me it is a place where water can accumulate." "Where I am long gone the top of the lava tube." "creating this huge hole." "It is here that I enter." "But it seems to be at forty feet." "but I to find a way to fall." "I put myself in the position a lost tourist on Mount Kilauea in Hawaii to show how to survive and get out." "I'm trying to get an old lava tube to find water." "It's just the fall with about a dozen meters." "These trees here called "ahea." "And what happens is that they grow here on the edge" "And the roots of these even grow down there." "They are looking for water and humidity." "I can use them to descend." "But they are all covered by this layer of moss what makes this a bit slippery." "Older lava tubes like this may prove hazardous locations." "Recently an American Fireman survived a fall of 30 meters a tube near here an operation rescue." "What is difficult here is to see the roots that are dead" "and those that are alive." "We have to test them first before we put them all our weight." "This is so slippery." "It's so difficult to cling to." "'m Thirsty but I know I should not drink the first water meet." "There is much moisture in this cave." "But the water itself may be contaminated because often animals fall in these holes eventually die." "What I want is to find water the bottom of this tunnel where I am sure it is clean." "But before going further into need to make a torch." "The nuts of the walnut-chestnut are rich in vegetable oil and burn easily." "Here is the very walnut-chestnut." "and walnuts should be here somewhere." "Native Hawaiians call "candlenuts using them to illuminate their homes." "That the need to do is open this locust a stone these give them a round and this is what I want." "Even the nut." "'ll stick the nuts on sharp sticks." "Green wood works best since it does not burn as fast." "What do I do now is perforate them with these sticks and make a kind of ..." "Skewer nuts that will burn slowly." "What you do is turn first the top then go burning upwards." "And each should take about 5 minutes." "if you put five on a stick" "I almost half hour of light in these tubes." "One is already." "And this small flame has another purpose that can save your life." "This will do more than give me light in the lava tube." "What will also make to alert me about the levels carbon dioxide inside." "It will work a bit like a canary in a mine." "One of the gases emitted by the volcano is carbon dioxide." "odorless and in large quantities is fatal." "If I go through an air pocket carbon dioxide the light goes off and that means I need to leave quickly." "I choke." "Carbon dioxide is not the only danger here." "I am 12 meters Underfloor there may be a landslide." "the safest way to walk precisely along the walls of the cave." "the lava circulated throughout the area." "You can see that it was so hot here almost like ceramic." "There's another hole where the rock should have given as the hole through which I entered." "But there is no water here I can drink." "we must continue to walk over there." "Just look at this." "You can see that these roots are growing up there and it is full of moisture." "Should be sufficient to fill completely my canteen." "Rainwater managed to pass through the cracks the top of the lava tube." "And now it's falling from the roots." "The most important is that this water is filtered and is clean and is so good that probably to be good to be bottled and sold in any restaurant." "All you need to do is filled." "Can not wait to drink it." "Is already full." "This water is so pure." "True volcanic water." "Is time back to the surface." "hear." "I have no idea what was that but it is better we leave here." "These ancient lava tubes are dangerous places." "It's time to get out of here fast." "I'm an old lava tube for water." "I found only one problem." "The noise came from here." "I am sure that these stones were not here" "I entered." "That's why these places are so dangerous." "Look." "I want out of this tunnel soon as possible." "The nearest exit is the hole that I saw" "I entered." "That is where we'll go before there is another collapse." "This is the hole where I when he was down." "But the rock is almost vertical." "Climb this is almost impossible without the proper equipment and I have none." "But there is a way." "The roots of a walnut-chestnut down the hole below." "I can use them to try to get out of here but this will be ..." "will be slippery and I hope that help me out here." "I to continue my path." "I'm trying to reach the coast but it is not easy." "This sun noon extremely hot and as is still so high is very difficult to follow leads especially in these forests with trees so tall." "'m Feeling quite claustrophobic here." "I just want to find now an area without trees." "When you find a clearing I can well see the sun can use the shadow the sun to see the direction." "But in this dense this is impossible." "I see a clearing." "Now be much easier see the way forward." "But there is a problem." "I can no longer use the sun as a compass." "The sun is now shrouded in clouds which means that I can not use it to guide me." "But what can I do is to use the wind." "The winds of the Pacific blow in the same direction." "Is why the sailors gave them that name." "The trade winds blow almost always from the northeast." "if you feel this side and I turn to that side this leads me to south to the coast." "the tropics night falls very fast especially forests like this." "I find shelter before dark." "One of the easiest shelter and faster to build is a shelter supported." "I need a ground no vegetation." "One of the most important to make a shelter is to have a good location." "It seems that there's a clearing." "Let's see." "this site is not very good." "You can see clearly that something happened here." "In truth must be ..." "be a wild boar." "Boars are extremely dangerous." "They have sharp claws and defend their territory at all costs." "I have to look elsewhere." "Look here." "Here will be excellent." "The nature here did all the work for me." "there are no spiders or poisonous snakes leeches and mosquitoes." "And I do not want to share my bed with any of them." "Before building the roof need to make the bed." "This dead vegetation will take to make a good mattress." "And although the roof keeps me dry is what keeps me warm." "Is the floor that is lost most of the heat of our body." "now I start building the structure." "These giant ferns will provide a perfect cover." "By making first the bottom building and go up any rain that falls going down the sides not through the roof." "I'll only end up with these here and this will prevent falling rain that even now started to fall." "And this is one of the rare situations that the timing of rain is actually perfect." "What I need now is to find wood for the fire." "Have a fire is very important." "Not only to heat but also to ward off insects." "The mosquitoes of the jungle are relentless." "Smoke distance will keep them at bay." "for some time." "The rain eventually erasing my fire." "It was not very smart my part let happen but I fell asleep for half an hour and this means that now mosquitoes are indulging me" "I'm just to be eaten alive here." "Not tonight will be very nice." "And to be honest ... just want to go home." "It is morning on Mount Kilauea." "My feet are suffering." "I have to have bubbles crossed the lava fields." "But I have to keep moving." "Listen." "Listen." "Are bees." "somewhere." "And if I can find the hive and get to the honey would be great." "Honey is full of sugars as glucose and fructose which I will very energy to continue." "Look." "Are there." "Look." "Look there." "Can you see them here completely crazy around that tree." "Many of the beehives of Hawaii were colonized by African bees." "And these are much more aggressive than native species." "If they are African bees it means big trouble." "do not like it none of this." "This would be   would certainly chopped everywhere if I tried to grab it." "I need another plan to achieve that honey." "The best to calm angry bees is with smoke" "And that's how it's done." "This is what I am looking." "These leaves of Monstera." "What I do is take two of these sheets will also take a pile of dry grass here" "Ok What I want to do with it is to put it up here this and wrap it tight" "wrap it ..." "I do a sort of mask." "I will use this shirt again mouth or ears." "Ok" "This is already done to be lit." "Now just pull above this up down here." "By squeezing it well 'm limiting the amount of air reaching the branches." "make smoke but it will create flame." "I need bring the smoke trying to calm them a bit." "The smell of smoke causes them to return to the hive voraciously feeding on the honey." "they become calmer and I get less likely to be bitten." "Ok I think it is good." "Got it." "Excellent." "The best honey is that it never goes bad." "Even when they found the pyramids everything had to do was re-heat it and is again good to eat." "It's so pure." "Thanks bees." "Honey gave me a great deal of energy to continue walking." "The coast should no longer be far away." "Look guys." "A clearing." "Was convinced that after this clearing would see the coast and the sea and a beautiful Hawaiian beach with palm trees." "it is only this." "It is so discouraging" "I'm exhausted by the volcano." "I get out of here and fast." "I'm going south seaward where I hope to meet people." "The ocean can no longer be several kilometers away." "is a huge lava field and cross it will be painfully slow." "The lava solidifies in different ways." "This part was formed when hot ash fell on the side of the volcano." "Cooled quickly forming these rocks extremely sharp." "I need another plan." "I'll be torn to pieces trying to walk here." "I'll take the shoes and see if I can use half as gloves." "Without any protection not much will be left of me when leaving this lava field." "Maybe this will help me to use them as gloves." "You can see how this is sharp." "Look at this." "Ripping them only to do this." "That's why I need of protection." "Thank God." "It was horrible." "I will say one thing." "I have seen many wild land but this must be the worst of all." "In the sky above me is the first clue that tells me that the ocean is not far away." "Look." "These birds are Koa'e kea." "It's a good sign." "They are sea birds and this means that I'm near the coast." "The birds are flying high means that are the way to the sea to feed themselves." "All you need to do is to follow them." "But the path is blocked by a major rift." "These cracks are caused the numerous earthquakes that plague the region." "Others are old lava tubes that gave completely." "Look at this." "Look." "You can see where the lava dropped by this loophole." "Just imagine the temperatures needed to melt this rock." "Going through these cracks fragile can be dangerous." "But there is a way to do it." "Sometimes there are these kind of bridges lava similarly we see snow bridges over cracks in the ice." "But to be very care through them because no one knows that is solid and what is hollow underneath." "This gap here is quite large." "Probably was formed by an earthquake but I get a way to cross it as I speak to there." "But it is impossible" "I can skip this." "or look for another bridge of lava or I'll have to go down and then go up the other side." "I think I'll get this bit down here." "Hawaii is one of the regions of the planet more seismic activity." "instead of being caused by the movement plate tectonics are caused by magma that will run inside the volcano." "There are at least 20 earthquakes day on this island." "And the earthquakes not only open cracks as well as the close." "I do not take me much here." "It seems that I see there a way out of this slot." "The walls of this cleft are formed by volcanic ash that does not almost no grip." "It is essential that I test each hole where I put my feet." "and this is what I was looking for." "The sea." "And that huge cloud of smoke is where the lava on which I have been flows to the sea creating this huge cloud." "I have reached the sea but this is a very dangerous place." "Those clouds are acid chlorides that form when hot lava reaches the sea." "They are highly corrosive and if I breathe are fatal." "All this site smells like a chemistry lab that anything not run any better." "The coast is full small towns and will quickly find people." "But it is important to make sure the safest way." "seems that would find so I'll try to go here." "A lava flow drain into the sea is simply spectacular." "But I have to keep the greatest possible distance." "Until meeting which was looking for." "Look." "Is there a building and some trucks." "And it's such a relief back to see signs of civilization." "I leave now with great respect the power of nature and this volcano." "this is one of the most extreme terrain where it was." "But for me is more than time to go home." "My travel is almost over." "There are very few places where we have contact with natural forces that form our planet." "And certainly that leaves me a huge sense of admiration."
