Never heard of them? Even better. Banda islands are part of Maluku islands and on the map they are a tiny dot. It’s not easy to get there but it’s so worth it. The locals are friendly, the food is good (lots of nutmeg and wild kenari almonds).
And the underwater world is… amazing. Maybe the best in the world. Island Ai and Hatta are the best for snorkeling, Banda Neira is the only one with diving schools, you can hike island Gunung Api which is an inactive vulcano, not to mention all the historic sites. Banda islands played a strong part in English and Dutch history.
