Dive Spot Guide•
Castle Rock
Castle Rock is Komodo's exposed pinnacle for big-fish drift dives.
Local operator required
Local timing matters for tides, pickup, and positioning on the pinnacle.
Boat-only and current-prone, it suits experienced divers who can handle blue-water drops, timed pickups, and fast-moving water.
About Castle Rock
Castle Rock is an exposed Komodo pinnacle that pulls in dense schools of fish and regular shark action when the current runs. The site rises close to the surface before dropping steeply, so most dives start in blue water up-current and settle onto the upper slopes and sheltered top. It is a boat-only site for experienced divers, with slack-tide timing, buoyancy control, and a clean pickup plan mattering more than depth chasing. Expect strong flow and excellent visibility rather than a relaxed coral-garden cruise.

Local Intel For Castle Rock
Community notes to help plan your visit.
Scuba Diving
Best suited to experienced divers due to strong currents; depths range roughly 4–30 m.
Freediving
Not a practical freedive site; the exposed pinnacle and current suit scuba boat dives rather than breath-hold sessions.
Snorkeling
Not a snorkeling target. The current, exposure, and offshore setup make it a scuba site, not a casual surface swim.
