Situated 6 km west of El Nido, this island is best known for a cave dive that can be found on the north side. The entrance is wide enough for two divers to enter together and a 15-20m tunnel leads to a cavern at the centre. The bottom is sandy where small fish and crabs can be seen.
The way out is more narrow and only one diver can exit the 10m tunnel at a time. It will bring you out to a rocky area some 20m from the entrance and you may see larger fish here.
NOTE: this dive should not be attempted when there is a strong north wind.
