Gamat Bay

A protected bay with a coral wall famous for mola mola sightings in the cold season. Calmer current than the open drifts — the right Penida site when conditions are rough.

The story

Where mola appear.

Gamat is a sheltered bay on Penida's north coast with a coral wall on the western side dropping into the deep. The bay is one of the most reliable mola mola sites in the cold-water season (August–October) — the deep thermocline rises closer to the surface here than at most Penida sites.

Outside of mola season, it's a relaxed wall dive with hard coral, gorgonian sea fans, and steady reef-fish life. A good alternative when Crystal Bay has too many boats.

"When the swell shuts the south, Gamat opens."

Conditions in Gamat are usually the calmest in north Penida — the bay geometry buffers swell and current.

Topography

How the dive unfolds.

A vertical coral wall on the western side of a sheltered bay. Mola mola rise from deeper water in the cold season.

Plan a typical 50–60 min dive: negative entry into the bay, descend along the wall to 22–25 m, hold mid-wall and watch the blue for mola, ascend gradually, safety stop at 5 m.
