Raja Ampat
Raja Ampat is an archipelago at the western tip of West Papua, Indonesia, centered on the Dampier Strait between Waigeo and Batanta islands. The Raja Ampat Marine Conservation Area records over 1,600 fish species and 75% of the world's known coral species. Diving is liveaboard, land-based homestay, or resort-based, with reef manta rays at cleaning stations the main draw alongside dense reef fish life and macro critters. Best months are October to April, when seas are calmer and visibility is highest; a marine park entry permit is required for all divers.
What makes it special
- Raja Ampat is one of the only places in the world where both reef manta rays (Mobula alfredi) and oceanic manta rays (Mobula birostris) are resident
- Cape Kri holds the record for the highest fish count on a single dive (374 species), set by marine biologist Gerald Allen
- Wayag Lagoon functions as a globally rare nursery for juvenile reef manta rays

Price is per person for a typical trip, excluding international flights ($ under $2,000 to $$$ over $4,000).
Budget homestay dive safaris from around $750 for 5 days/4 nights (land-based, shore/day boat diving); mid-range liveaboards $3,000-4,500 for 7 nights; premium liveaboards $4,500-8,000 for 7 nights. Flights to Sorong and the ~$100 marine park permit are additional.
Best time to dive
- Current
- Moderate
- Water temp
- 27–31°C (coldest Aug, warmest May)
- Getting there
- Moderate — Reachable but with some friction: 1 domestic flight, a 2h boat crossing.
- Experience
- Most liveaboard operators recommend Advanced Open Water certification with 50+ logged dives, since most dives are drift dives in currents that can run strong through the Dampier Strait. Open Water divers can still dive sheltered sites like Manta Sandy and Arborek Jetty.
Nearest airports
- SOQ — Domine Eduard Osok Airport (Sorong) (Domestic flights from Jakarta or Bali (Denpasar), then ferry or speedboat transfer to Raja Ampat)
- RJM — Marinda Airport (Waisai) (Small-aircraft (ATR-72) connections; a secondary entry point directly into Raja Ampat, avoiding the Sorong ferry transfer)
Permit required
All divers must purchase a Raja Ampat Marine Park Entry Permit (SIM/TAG card), valid for one calendar year across the whole regency.
Approximately $100 total (marine park tag around 1,000,000 IDR plus an environmental service fee around 500,000 IDR), paid once per calendar year.

Resident year-round across most reef and rubble sites; one of the most consistently found macro subjects in the region.
Dive sites
Worth knowing before you book
- A mass coral bleaching event, likely driven by marine heatwaves and cyanobacteria blooms, was recorded across central Raja Ampat in November-December 2024 — recovery is ongoing and site-dependent.
- Overtourism is a documented problem at the most popular manta cleaning stations: more than 60 divers were reported in the water simultaneously at one site in December 2023, exceeding what researchers describe as the reef's ecological carrying capacity.
- Most dive sites involve real current and are recommended for Advanced Open Water divers with 50+ logged dives; Open Water divers are limited to a handful of sheltered sites.
- The wet season (June-September) brings rougher seas, reduced visibility (sometimes under 15m), and many liveaboard operators suspend or reduce operations.
- Access is remote and adds real time and cost: international arrival is typically via Jakarta or Bali, then a domestic flight to Sorong, then a ferry or speedboat transfer.

Note on the data: Overcrowding claim (60+ divers at one manta site) is from a single environmental-NGO source (The SEA People) — worth a second cross-check before flipping needsReview to false. Bounding box is an approximation based on the known island cluster, not a surveyed boundary. Price range floor is based on land-based homestay dive safaris, which are a materially different product from liveaboard diving; consider whether the UI should distinguish these more clearly than a single price range can. Water temperature: Tropical and near-flat all year, roughly 28-30C; a shallow dip in Jul-Aug (southeast monsoon) is the only real seasonality. Bands are the published monthly min/max satellite range rounded to the nearest half-degree; no thick-wetsuit season. Access: International arrival is via Jakarta or Bali, then one domestic flight to Sorong (SOQ, domestic-only); liveaboards board at Sorong harbour ~10-20 min from the airport, while homestays and resorts add a ~2h ferry/speedboat crossing to Waisai — the marquee Dampier Strait diving is reachable land-based, not liveaboard-only.
