Seasonal Marine Highlights
There are some great seasonal marine life highlights to be aware of when planning a dive trip to Raja Ampat.
- Manta Ray Season: October to April. Sites like Manta Ridge and Blue Magic are prime spots for manta ray encounters during this period.

Dive Experience Needed
Raja Ampat caters to a wide range of divers, but due to the strong currents in many dive sites, it’s generally recommended for experienced divers. Some of the more challenging sites can have unpredictable currents that require good buoyancy control and confidence in drift diving.
It’s a good idea to complete a drift diving and a perfect buoyancy course before your trip so you can handle the conditions safely. Some dive sites in Raja Ampat also feature deeper sections, so you may wish to complete a deep diving certification as well.

What is the Best Way to Dive Raja Ampat?
Given its remote location and the spread-out nature of the islands, the best way to dive Raja Ampat is via a liveaboard. Liveaboards offer the advantage of taking you to the best dive sites across the archipelago, including the more remote areas like Misool and Wayag.
Raja Ampat liveaboards range from budget to luxury options, with trips typically lasting from 7 to 14 days. These trips offer multiple dives per day, including night dives, allowing you to explore the full breadth of Raja Ampat’s dive sites.
That said, there are several eco-resorts in Raja Ampat that offer day trips to nearby dive sites. While this option provides more flexibility and comfort, you’ll be limited to dive sites within reach of the resort. Resorts are great for those who prefer a land-based experience but still want to enjoy world-class diving.
