Siquijor diving and snorkeling is world-class. We can help arrange with a dive shop or you can go directly to dive shops near White Villas Resort. Corals are still in good condition with diverse marine life and good chances of seeing for example turtles. Please take care not to touch or damage the corals. You are not allowed to collect or catch any marine life in the sanctuaries.
For snorkelers there are nearby sanctuaries in Maite, Tubod and Paliton. We highly recommend Tulapos Marine Sanctuary on the northeastern side of the island. Every time we have visited we have seen a large school of young barracuda, several turtles, and reef sharks.
