East of Java, a chain of islands runs for more than 1,000 kilometres: Bali, Lombok, Sumbawa, Flores, and on to Alor. Together they're called the Lesser Sunda Islands, and between every pair of them lies a strait full of current and life. Many liveaboards follow this route.

The ten regions, west to east

Why the straits matter
The Lesser Sunda Islands form a wall between the Pacific-fed seas of Indonesia and the Indian Ocean. Water has to squeeze through the straits between them, like the Lombok Strait between Bali and Lombok or the Pantar Strait off Alor. That's what brings the nutrients, the big animals and the cold upwellings, and also the currents. See the Indonesian Throughflow on our Coral Triangle maps →
Land-based or liveaboard?
- Land-based works best for Bali, the Gili Islands, Komodo (from Labuan Bajo) and Alor (from Kalabahi). Each has an airport nearby.
- Liveaboards reach the places in between, like Moyo and Sangeang, and string several regions together in one trip, often between Bali and Komodo or Komodo and Alor.
