Deep Rock

A rocky pinnacle from 14 m to 34 m, dived on tide changes

Deep Rock is a rocky pinnacle about ten minutes by boat north of Malapascua port, with its top at 14 metres and its deepest part at 34. It is described as expert diving for divers who want current: intermediate to strong flow runs on tide changes, and the dive is planned around the state of the tide as much as around the depth.

The dive

The run out is short — around ten minutes from Malapascua port to the north side — but this is not a casual dive. It is a deep rocky pinnacle, with the top at 14 metres and the deepest part at 34, so the descent is quick onto the crown rather than a drift down a line. Groups regroup on top before dropping down the side, because losing the rock in current means losing the dive.

The site is dived for expert diving on intermediate to strong current at tide changes, and the sensible profile is to work the deep side early while everyone is fresh, then spend the rest of the dive spiralling up the structure. Depth is the limit rather than gas: at 34 metres no-decompression time is short, and the ascent starts from the shallow crown at 14 metres, with the safety stop hung above the rock or on a line.

Season follows Malapascua: Threshers visit Kimud Shoal all year. March to May is calmest and clearest; October to January brings rough seas, green water and the most cancelled crossings.

Know before you go

  • Current runs intermediate to strong on tide changes; the dive is timed around the tide and divers stay in contact with the rock rather than drifting off it.
  • The deepest part is 34 metres, so no-decompression time is short and the profile has to be planned deep-first with a hard turn depth.
