Hotels, dive operators, gear, and how to get here are on the Komodo National Park location page.

Overview

A single rocky pinnacle in the middle of Komodo's central straits. Currents split around it, leaving one side calm enough to drift the wall while the other rips overhead at three knots. Nutrient flow keeps the reef carpeted in soft coral and stacked with reef fish from 5 m to 40 m+.

Briefing note

Always brief the current direction with the guide. Wrong side of the pinnacle = blown off the wall.

How we summarise this

We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.

Gear for this site

Beyond the basic kit
  • Reef hook with lanyardCurrent can pin you to the wall — hooking onto dead reef saves air and posture.
  • Heavier wetsuit (mid-year)Southern Komodo upwellings drop the water temperature sharply in June–September. Layer up.
  • SMB + reelDrift exits put you in shipping channels. SMB up before ascent is non-negotiable.
  • Dive computerDeep, current-rich dives — accurate NDL tracking matters.
