Tenerife

In the final programme in the series, Brett Westwood follows the tourist buses up Tenerife's famous volcano and finds out why most of the wildlife here is found nowhere else in the world.

With the help of two experts from the local university he discovers birds and reptiles that have learned to live alongside the many tourists who visit the island.
