Grylls is dropped by helicopter at the top of Mount Kilauea. Made up of an expanse of solidified lava which stretches for 33,000 acres, this environment is one of the world's most inhospitable. He first traverses lava fields, which catch his boots on fire, then heads into the jungles of Hawaii. Grylls uses a kukui nut torch to explore a lava tube and finds water, then uses smoke to placate a bee hive to get honey. Ultimately, he finds the sea (and people) by following seabirds.
