Nigel Marven's Wild Philippines

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.

Nigel visits Bohol's world-famous Chocolate Hills, strange mounds of dissolved coral around 45 million years old, and the iconic Mount Apo.
