Overview

A current swept pinnacle in the far north of Komodo National Park, 300 m from Castle Rock, rising from open water to break the surface at low tide. A submerged spur falls away to a saddle near 20 m, its walls stacked with giant sea fans, barrel sponges, and soft coral in reds and orange. The water is famously clear, often well past 25 m, which is how the site earned its name. When the tide runs, grey reef and whitetip sharks hold in the flow on the up current side while clouds of fusiliers, snapper, and surgeonfish wrap the slopes and anthias swarm the shallows. Plate corals around 17 m shelter resting whitetip pups.

Briefing note

Negative entry and consistently strong current make this an advanced dive, not a spot for new divers. Surface on the down current side and never up current of the rock. Komodo National Park entry and ranger fees apply, and most divers reach the far north on a liveaboard rather than a day boat.

Gear for this site

Beyond the basic kit
  • Reef hookThe crown of the seamount sits in ripping current, and hooking into bare reef is the only way to hold position while the sharks and schooling fish stream past.
  • SMB and reelDrift exits put you over open water, so send a marker buoy up before you ascend.
