Overview:Stephen's travels continue in Costa Rica, where he encounters poison-dart frogs and falls in love with a baby sloth at a biological research station. But he soon finds there is more to the country than conservation and eco-tourism as he ascends volcanoes, descends white-water rivers and experiences the passion of a football derby in the capital of San Jose. He then crosses over into Panama for the final leg of his trip, witnessing giant leatherback turtles coming ashore to lay their eggs and learning how to dredge the canal in Panama City.
