Bas Coral is a wall and reef site on the Olango side of the channel, reached by banca from Kontiki Port on Mactan. The maximum depth is 35 metres and visibility averages 10 to 30, with corals and tropical reef fish along the wall face. The current here runs rather strong, which is the first thing to plan the dive around.

The dive

The boat leaves from Kontiki Port on Mactan and runs across toward Olango Island, so this is a crossing rather than a hop along the strip. The site is a mix of walls and reefs with the maximum depth at 35 metres, and average visibility of 10 to 30 metres means how much of the face you take in at once varies with the day rather than with the depth you are at.

The water moving through this stretch is what defines the dive: the current here is described as rather strong, and it has to be planned for before the descent rather than dealt with afterwards. Along the wall the ground carries corals and a variety of tropical reef fish, and the practical way to dive it is to go in up-current, keep the face on one shoulder and let the water do the work of covering ground.

Season follows Mactan & Olango: Mar–May, the hot dry season, is the usual window; the Jun–Nov rains cut visibility on the house reefs, and typhoon risk runs highest around Nov–Dec, as Typhoon Rai showed in December 2021.

Know before you go

  • The current is described as rather strong, so the descent is made straight onto the wall and the dive is planned to run with the water rather than across it.
