Episode 4

Seven young explorers relive the legend of Sir Walter Raleigh. The team splits in two, with half undertaking a long horse ride in search of the legendary lost city of El Dorado, while the others attempt to become the first ever children to stand on the furthest point of Mount Roraima's triangular table-top summit. But to reach it they will have to cross a treacherous ravine more than nine thousand feet up, and the weather is closing in.
