Raja Laut - dive in IndonesiaEvery diver knows that Indonesia boasts some of the best diving on the planet. It is the epicenter of coral and fish life biodiversity. Due to its vast area there are only a handful of resorts (mostly around Manado and Lembeh Strait, and a few in Raja Ampat). It is truly a liveaboard destination and there are more than 50 Indonesia liveaboards waiting to whisk you away to the country’s best dive regions.

Use this handy guide to get an overview of the different routes and seasons.

Set sail on a Phinisi – Indonesia’s traditional, wooden sailboat – or board a yacht-style, wood or steel liveaboard. Most of Indonesia’s liveaboards spend the winter in Raja Ampat and summer in Komodo, and many offer spectacular transitional routes in between.

Indonesia’s Best Liveaboard Routes

At almost 2 million square kilometers, Indonesia encompasses dozens of liveaboard routes. Not every liveaboard covers every route however, and most only visit specific areas at certain times of the year. So, as a jumping-off point for discovering the most desirable dive destinations, here’s a brief rundown of where and when to dive in Indonesia.

Raja Ampat

Many divers visit Raja Ampat for the incredible number of mantas that migrate through the area each winter. But with some of the highest fish counts in the world – and experiences ranging from drift dives to mucking – Raja Ampat’s consistently warm, clear waters are a treat to explore any time.

Typical Liveaboard Departures: October to May (many itineraries include other dive regions). The Dewi Nusantara also offers August and September departures.
