About Indonesia

Indonesia is the world's largest archipelago, thousands of islands spread along the equator between the Indian and Pacific oceans. Bali's temples and rice terraces, Java's volcanoes and Borobudur, Sumatra's rainforest and orangutans, and the reefs of Komodo and Raja Ampat are its best-known highlights. The dry months from May to September suit most island travel, while the wetter months bring heavy rain and quieter roads.
