What the diving is like
Shore diving, which is what makes it different. The muck sites run along a black sand coast south of Dumaguete and are entered from the beach through light surf, walked in with a guide who knows the entry. The ground is fine volcanic sand off the massif behind the coast, on a gentle even slope; depth is a function of how far out one swims rather than of any drop, and it is easy to spend a dive shallower than intended. Lines of concrete pyramids, tyres and sunken car bodies have been set across the sand to give the animals somewhere to be, and they double as the navigation, so a dive tends to be a slow crawl from one structure to the next rather than a route. Between them the sand looks empty and is not. Surf is the variable. The beach faces the channel towards Cebu and Siquijor, and a swell that would be nothing from a boat makes an entry, and more particularly an exit, awkward. Boat diving exists but is not the point.
The shape of a day
Two shore dives in the morning, a break, and a third in the afternoon or after dark. Entries are short walks from the road and the tank is carried for you at most operations. The artificial reefs are the navigation, so a dive tends to be a slow crawl from one structure to the next rather than a route. Apo Island, a marine reserve with genuine reef and current, is a separate boat day and worth one.
Getting there
Sibulan airport at Dumaguete is twenty minutes from the Dauin resorts, with several flights a day from Manila and Cebu. It is one of the easiest muck destinations to reach in the region, which is a large part of its appeal.
When to come
November to June. The northeast monsoon can put swell on the beach in December and January and make some entries awkward rather than impossible. July to October is wetter and the sea is often flatter, so the shoulder months are underrated.
Fees and what is not included
The Masaplod and Dauin sanctuaries charge entry, collected on the beach, and Apo Island charges separately. Shore diving means a lower daily cost than a boat destination, and unlimited house-reef diving is common.
