This challenging mountain bike ride will take you through the dramatic, volcano-strewn (14 active) island of Flores in Eastern Indonesia.

The Sepik River is one of two vast tropical river systems in Papua New Guinea that meander through the densely forested lowlands of the world's second largest - and the world's tallest - island. Along the banks of the river and its many tributaries live sparsely scattered, remote villages scarcely contacted by the outside world, where people live a lifestyle that has changed little for thousands of years.

The Indonesian island of Sulawesi is ideal for adventurous cyclists: this is for riders who want the physical challenge of tropical mountains, who are looking for cultural adventure in a traditional Asian society off the beaten track, and who view the unpredictability of travel in a developing country as something to be expected and enjoyed.

The mountainous provinces of the Cordillera, Northern Philippines, are perfect for trekking. This is the territory of former headhunting tribes who were also the master hydro engineers who constructed the world's first and most impressive rice terraces over 2000 years ago - considered by some to be the eighth Wonder of the World.
