Cleaning stations
Coral bommies where mantas hold position while cleaner wrasse and butterflyfish work their skin and gills. Adults, especially females, stay longest.
The Guide · Karang Makassar
A reef plateau that mantas come back to
Karang Makassar is open water inside Komodo National Park — no island, no jetty. Reef mantas hold over the coral to be cleaned, and have done long before it had a tourist name.
Plan your visitIn short
A shallow reef plateau 40–45 km by sea from Labuan Bajo, where reef mantas feed and are cleaned year-round. Eight to eighteen metres, mild to moderate current, and it works for snorkellers and Open Water divers on the same boat.
- No island, no jetty — you arrive and leave by boat
- Resident reef mantas, not a seasonal migration
- December to March for the largest gatherings

A plateau, not an island
Karang Makassar is a long rubble-and-coral shelf lying in the channel between Komodo Island and the islands to its east. There is no beach and no building; every visit begins and ends on a boat.
The bottom is sand, rubble and scattered coral bommies rather than a wall. Those raised heads are the working cleaning stations — fixed points where mantas hold while cleaner fish go over them.
Because the shelf is shallow and current-swept, visibility and water movement turn with the tide. A guide times the entry against the tide table, not against the clock.
Why here
Why the mantas keep returning
They are not resting here. They are working the plateau — feeding on one pass, queueing for a clean on the next.
Plankton on the tide
The channel funnels nutrient-rich water between the islands. Sightings cluster around tide changes, and the wet season brings the densest blooms.
A social venue
Cleaning stations double as courtship grounds. Undisturbed, mantas return to the same coral heads; crowded, they stop coming.

Neither carries a stinging barb, and neither has any interest in you. The only real risk here is a swimmer blocking a feeding or cleaning pass.
Snorkel, dive, or both
The plateau sits shallow enough that both formats work off the same boat on the same day.
Snorkelling
No certification. You hold the 2–5 m shelf while mantas pass beneath you. This is what most day trips from Labuan Bajo are built around.
Diving
Open Water is enough on a normal day. You sit level with the cleaning stations at 10–15 m and drift with the tide rather than swimming against it.
Photography
Shallow water means natural light still reaches the reef, which is why this is a wide-angle site. No flash at close range.
Neither format guarantees an encounter. These are wild animals following food, not a scheduled attraction.
