Imbekwan Bommies
0.3997°S 131.2043°E · pinnacle
Imbekwan Bommies is a pinnacle and bommie dive site in the outer islands of Raja Ampat, West Papua, Indonesia. The site features a cluster of isolated coral heads (bommies) rising from a deeper sandy substrate — a formation that attracts concentrated marine life in the open water around the pinnacles.
Overview
Each bommie functions as a micro-ecosystem, drawing cleaning fish, shelter-seekers, and hunters to the same structure. Coral coverage is dense on the upper and mid-sections of each pinnacle, with encrusting sponges, sea fans, and tunicates covering the deeper sides. The spaces between bommies are productive hunting grounds for whitetip reef sharks, which rest in the sand during daylight hours and become more active as dusk approaches.
Schools of batfish circle the tallest pinnacles, while lionfish and scorpionfish occupy overhangs and ledges where they wait in ambush. Nudibranchs and flatworms crawl across encrusting growth, and cuttlefish are frequently spotted hovering near coral structures. The sandy channels between bommies hold garden eels and the occasional flamboyant cuttlefish for those who search carefully.
Visibility typically runs 15–25 metres. Water temperatures average 27–29°C. Currents can vary between bommies depending on tidal phase.

Dive Profile
Divers navigate from bommie to bommie at 10–30 metres, spending time at cleaning stations and searching ledges for cryptic species. The multi-pinnacle layout rewards systematic exploration. Entry and exit are by boat.
