Raja Ampat is a place to dive between October and April, once you have Advanced Open Water and some current experience. The currents feed the reefs, and they also decide who can dive them.
It sits in the Coral Triangle, off the north-west tip of Bird's Head Peninsula in West Papua. The name means "Four Kings", for the four main islands of Waigeo, Batanta, Salawati and Misool. UNESCO's biosphere reserve listing says the reefs host over 75% of all known coral species and more than 1,320 species of coral reef fish (UNESCO).
When to dive Raja Ampat
The north-west monsoon brings dry weather and calm seas from October to April, so liveaboards can cover the whole archipelago. It is also when plankton blooms draw mantas to the cleaning stations.
The south-east monsoon runs from May to September and brings wind and rain, especially to the south around Misool. Many resorts in the central region stay open all year. Many liveaboards move to the Komodo region.
October and April are good months, and May and June are the shoulder months: quieter, and a little cheaper than peak season. Aim for November to March for mantas and December to February for the calmest conditions at Misool.
Currents are part of the diving here. New and full moons bring the strongest flow, which means the best pelagic action and the most demanding diving. Ask your operator how they choose sites around the lunar cycle.
Month by month
Peak runs from November to March. July to September is the off season, and July and August are the stormiest months.
| Month | Conditions | Go for |
|---|---|---|
| January | Peak | Mantas at the Dampier Strait and Misool cleaning stations, macro life, reef sharks |
| February | Peak | Mantas, macro life, reef sharks |
| March | Peak | Mantas, macro life, reef sharks |
| April | Good | Macro life, reef sharks, mantas at the tail end of their season, with fewer crowds |
| May | Shoulder | Macro life, mantas only occasionally. The wet season is starting: rougher spells, and plankton can cut visibility |
| June | Shoulder | Macro life, mantas only occasionally |
| July | Off | Mantas only occasionally. Stormiest months: strong southern winds, and many liveaboards suspend operations |
| August | Off | Mantas only occasionally. Still among the stormiest months |
| September | Off | Mantas only occasionally |
| OctoberNow | Good | Macro life, reef sharks, mantas. Calm seas return and the mantas begin to arrive |
| November | Peak | Mantas, macro life, reef sharks |
| December | Peak | Mantas, macro life, reef sharks |
From our Raja Ampat season record, checked 9 October 2026, which draws on published season calendars and our own Raja Ampat guides. Hammerheads and whale sharks are scored as occasional sightings, so they are not listed. Mantas from May to September are scored as occasional too, and the table says so instead of leaving them out.
Where to dive in Raja Ampat
Central (Dampier Strait). The strait channels nutrient-rich currents between the islands, and the fish life follows. At Cape Kri the ichthyologist Gerry Allen counted 374 fish species on a single 90-minute dive in 2012, the highest tally he had recorded on one dive.
North. Less current-driven and more intimate. The Passage is a narrow channel between islands, 3–15 m deep, where light filters down to the soft corals.
South (Misool). Remote and harder to reach, with dense soft coral. Magic Mountain is a cleaning station for both reef and oceanic mantas. Most liveaboards that include Misool add 2–3 days to the itinerary.
| Site | Depth, level | Known for |
|---|---|---|
| Cape Kri (Dampier Strait) | 5–40 m, Advanced | A single-dive count of 374 fish species (2012) |
| Blue Magic (Dampier Strait) | 10–30 m, Advanced | A submerged pinnacle with oceanic mantas and grey reef sharks |
| Sardine Reef (Dampier Strait) | 5–30 m, Intermediate | Schools of fusiliers, surgeonfish and trevally |
| Melissa's Garden (Dampier Strait) | 5–25 m, All levels | A hard coral garden |
| The Passage (North) | 3–15 m, Intermediate | A narrow, river-like channel with soft corals |
| Wayag (North) | 5–20 m, All levels | Shallow reefs that most levels can dive |
| Boo Windows (Misool) | 5–30 m, All levels | Swim-throughs in a rock face, ringed with bright soft corals |
| Magic Mountain (Misool) | 7–25 m, Advanced | A cleaning station for reef and oceanic mantas |
| Nudi Rock (Misool) | 5–30 m, All levels | Macro life and colourful nudibranchs on a ridge |

Which level do you need for Raja Ampat?
The strong currents do not close Raja Ampat to less experienced divers. They mean being honest about where you dive and with whom.
The central region around the Dampier Strait has shallow coral gardens with manageable current and good visibility, which suit confident Open Water divers. Melissa's Garden and Wayag are accessible at most experience levels.
The high-current pinnacles are a different matter. Cape Kri, Blue Magic and Magic Mountain need Advanced Open Water at minimum, and solid buoyancy and some current-diving experience are strongly recommended. Without both, you will work too hard to enjoy what is around you.
Get to Advanced Open Water with 30–50 dives before you go. Spend time on mastering your buoyancy and on your ascents and descents. The coral here is dense and fragile, and one bad fin kick in the wrong place does damage that takes years to recover.
What you'll see in Raja Ampat
Reef and oceanic mantas use the cleaning stations in the plankton-rich months. Grey reef sharks and giant trevally patrol the blue, and schools of thousands of fusiliers and jacks form silver clouds. For macro, pygmy seahorses sit in the sea fans and wobbegongs lie camouflaged on the reef. The "walking shark" is the endemic epaulette shark.
The reefs also hold eagle rays, sea turtles, Napoleon wrasse, moray eels, octopus and nudibranchs. Whale sharks and hammerheads turn up only occasionally, so they are not a reason to book.
Raja Ampat: liveaboard or resort?
Take a liveaboard for a first trip: the archipelago is too big to cover from one base. A resort suits a return visit, when you want to learn one region well.
Choose a liveaboard if you want the whole archipelago in one trip: Dampier Strait, the north and Misool. A 7–10 day itinerary covers more than a resort base can, and reaches remote areas that resort boats cannot reach efficiently. You can also combine it with Komodo and the Banda Sea in one trip. The Raja Ampat liveaboards planning guide covers cost, season and boats, and the 2026 Raja Ampat liveaboard rankings cover every tier.
Choose a resort if you want to go deep into one region. A week at an eco-resort on Kri Island, diving the Dampier Strait every day, is a strong trip in its own right, and you learn those sites better than a liveaboard diver passing through. Resort stays also support local communities more directly.

Questions
What is the best time of year to dive Raja Ampat?
October to April is the prime season: dry weather, calm seas and peak manta activity as plankton blooms draw them to the cleaning stations. May and June are the shoulder months, with fewer boats and often lower prices.
From May to September the south-east monsoon brings rougher conditions to the south, though the northern sites and the central Dampier Strait remain diveable. Many liveaboards move to Komodo during the southern wet season.
Can beginners dive Raja Ampat?
Some sites, yes. The shallow coral gardens around the Dampier Strait suit confident Open Water divers, and Melissa's Garden and Wayag are accessible at most levels. The high-current pinnacles (Cape Kri, Blue Magic, Magic Mountain) need Advanced Open Water at minimum. Aim for Advanced Open Water and 30–50 dives before you go.
How do I get to Raja Ampat?
Fly into Sorong (SOQ) in West Papua, the gateway city to the archipelago. Most international travellers connect through Jakarta (CGK), Makassar (UPG) or Manado (MDC).
Liveaboard operators typically meet guests at Sorong airport and transfer them directly to the harbour. The logistics are well established, and it is less complicated than it looks on a map.
Is Raja Ampat worth the cost?
For a serious diver, yes. The Dampier Strait gives accessible sites and Misool gives remote diving, in one destination. The entry fee is roughly USD 60, paid once (as of 17 September 2026). The boat is the real cost, so compare the full price in the ranked list and pick the right season.
Do I need to pay a fee to dive Raja Ampat?
Yes. International visitors pay Raja Ampat's regency entry fee: IDR 1,000,000 per person (roughly USD 60), charged once and not per day, as of 17 September 2026 (rajaampatbiodiversity.com). Pay it online in advance through the official tourist registration system and keep the entry pass it emails you. Paying at the port is a fallback.
A separate marine-park charge, collected by the provincial marine protected area authority, changed in August 2026, and the source prints no amount. Ask your liveaboard or resort for the current figure by email when you book, and confirm any park and port fees they add. The authority sells the marine-park card on its own site, kkprajaampat.id. The marine-park charge funds the management of the protected area, including ranger patrols.
Which are the best dive sites in Raja Ampat?
It depends on your level. Cape Kri, Blue Magic and Magic Mountain are Advanced dives in strong current, for fish counts, mantas and grey reef sharks. Sardine Reef and The Passage are Intermediate. Melissa's Garden, Wayag, Boo Windows and Nudi Rock are open to all levels. The site table above gives depths and levels.
What will you see diving Raja Ampat?
Reef and oceanic mantas use the cleaning stations in the plankton-rich months, and grey reef sharks, giant trevally and silver clouds of fusiliers patrol the blue. For macro, pygmy seahorses sit in the sea fans and wobbegongs lie camouflaged on the reef. UNESCO credits the reefs with over 75% of all known coral species and more than 1,320 species of coral reef fish (UNESCO). Whale sharks and hammerheads turn up only occasionally, so they are not a reason to book.
When do you see manta rays in Raja Ampat?
Aim for November to March, when mantas are at their best at the Dampier Strait and Misool cleaning stations. In our Raja Ampat season record, checked 9 October 2026, mantas begin to arrive in October. April is the tail end of their season, and from May to September they are only occasional.
Is a liveaboard or a resort better in Raja Ampat?
A liveaboard suits a first trip, because a 7–10 day itinerary covers the Dampier Strait, the north and Misool. A resort suits a return trip to one region, such as a week on Kri Island diving the Dampier Strait. The Raja Ampat liveaboards planning guide covers cost, season and boats, and Raja Ampat: liveaboard or resort? compares the two.
