Nigel Marvin travels to the Philippines, a country with a greater variety of life per square mile than any other nation.
Nigel visits Bohol's world-famous Chocolate Hills, strange mounds of dissolved coral around 45 million years old, and the iconic Mount Apo.
The world's 15th largest island and the largest island in the Philippines is a land of contrasts; from the urban sprawl of the capital Manila to huge hidden forests; species-rich reefs and a dozen active volcanoes that dominate the skylines.
Palawan, also known as the Last Frontier, is the most westerly island in the archipelago; Nigel explores its ancient rainforests, coasts, coral reefs and underground treasures.
