Site Profile

An exposed offshore pinnacle ~1.5 nautical miles from Cape Kri. The dive almost always demands a negative entry to get below the surface chop. Divers descend to the up-current split point, hook in, and observe.The primary attraction is the consistent presence of large marine life. During Dec–Mar, oceanic manta rays (Mobula birostris) visit multiple cleaning stations on the reef plateau. A resident school of bigeye trevally numbers in the thousands, forming a tornado-like vortex. Large Spanish mackerel and tuna hunt fusiliers off the reef edge.The currents are unpredictable and can shift mid-dive — a site reserved for experienced divers comfortable with negative entries and reef hooks.

Dive Plan

  1. 01

    Negative entry from the tender

    Drop in, dump air, descend immediately. Otherwise the chop and current will sweep you past the pinnacle.

  2. 02

    Hook in at the up-current split

    Reach the reef top at 7–15m. Find the current shadow. Hook in to stabilize. Save air.

  3. 03

    Observe the cleaning station

    Mantas come in to be cleaned. Stay low against the reef. Cameras up — wide angle.

  4. 04

    Slow ascent through the trevally

    Release the hook. Drift up through the silver tornado of bigeye trevally. Multi-level safety stop.
