Expedition Borneo

A team of explorers set out on a wildlife adventure to the tropical island of Borneo for the elusive clouded leopard and the rare Borneo gibbon.

Steve Backshall and his team decide to press on with their ascent of Mount Kuli.

The explorers have a close encounter with a giant python; one of the team is bitten by a deadly coral snake; there's a major breakthrough as they go in search of the wild orangutan.

One team is hunting for bats, snakes and giant spiders, whilst the other finds cave paintings made by an ancient rainforest people.

Steve Backshall and his colleagues attempt a daring descent; they go through the sinkhole in the middle of a mountain.
