Sumatra
Orangutans in the wild, a volcanic crater lake the size of a country, and almost no tourists

Sumatra is where you go to see orangutans in genuinely wild rainforest — Bukit Lawang and Gunung Leuser National Park are two of the last places on Earth with wild Sumatran orangutans. Lake Toba, the world's largest volcanic lake, is a full day's travel but stunning and virtually tourist-free. Infrastructure is rougher than Bali or Java, which is exactly the appeal for travelers chasing something less packaged.
