The World's Most Biodiverse Dive Site
374 species counted in a single dive — the world record for fish diversity. This extraordinary reef at the crossroads of Dampier Strait's nutrient currents creates a marine concentration unmatched anywhere on planet Earth.
Dr. Gerald Allen's Discovery
Dr. Gerald Allen's record-setting species count stunned the marine biology community and cemented Raja Ampat's position as the global epicenter of marine biodiversity. To put 374 species in perspective: many popular dive destinations worldwide contain fewer total species across all their sites combined.
At Cape Kri, this extraordinary concentration occurs on a single reef, on a single dive, in approximately 90 minutes of observation.
Why Here?
Cape Kri's position at Dampier Strait's narrowest point accelerates tidal currents carrying nutrients from the Pacific Ocean. This nutrient conveyor belt supports an explosion of plankton growth, which feeds small fish, which attract larger predators — creating a complete marine food web of staggering complexity visible at every depth from surface to beyond 30 meters.
Every Square Meter Alive
Spectacle
Massive schools of barracuda, fusiliers, surgeonfish, and big-eye trevally create living walls of movement. Bumphead parrotfish cruise in herds of 20-50. Schools so dense they block sunlight from the reef below. The biomass concentration is visually overwhelming.
Predators
Blacktip, whitetip, and grey reef sharks patrol the current lines. Giant trevally hunt the reef edges. Napoleon wrasse approach with characteristic curiosity. Barracuda schools spiral in silver columns extending from reef to surface.
Foundation
Every square meter supports dozens of species. Anthias clouds in orange and purple, damselfish territories, butterflyfish pairs, angelfish, and wrasse species fill every niche. Hard coral in excellent condition provides the foundation.
Miniature Marvels
Pygmy seahorses on gorgonian fans (Hippocampus denise and H. bargibanti), ornate ghost pipefish, Pontoh's pygmy seahorse, blue-ringed octopus, nudibranchs in extraordinary variety, and flatworms. Rewards both wide-angle and macro photographers.

Cape Kri Questions
Advanced Open Water certification is recommended due to moderate to strong currents. Experienced Open Water divers with 50+ logged dives and good buoyancy control can dive Cape Kri with experienced guides. Our dive masters assess conditions and position divers appropriately for skill level.
Yes — the reef top at 5 meters offers excellent snorkeling with extraordinary fish density. Snorkelers see many of the same schooling species from the surface. However, the strongest current action and predator encounters occur deeper. Cape Kri snorkeling is best in calm conditions with an experienced guide.
October to April delivers the best conditions. November through February offers peak visibility (up to 30m) on incoming tides. The site is diveable year-round, but currents are more predictable and seas calmer during peak season. Dawn dives on incoming tides typically produce the most impressive fish aggregations.
We recommend at least 2-3 dives at Cape Kri across different tidal states. Incoming tide produces the best fish schools and predator activity. Slack tide allows relaxed exploration of macro subjects. Outgoing tide brings different species compositions. Each dive feels like a different site.
Cape Kri is one of the world's premier underwater photography sites. Wide-angle shooters capture schooling fish, sharks, and reef panoramas. Macro photographers find pygmy seahorses, nudibranchs, and ghost pipefish. The challenge is choosing — every direction offers a potential portfolio shot. Nitrox extends bottom time for longer shooting sessions.
