Dauin is a small (about 25,000) seaside municipality south of Dumaguete in Negros Oriental. It is bordered on the east by the seashore, one the north by Bacong, on the south by Zamboanguita, and on the west by Santa Catalina.
In addition to diving-related tourism, the town is also seeing quite a bit of residential real estate development, much of it upmarket. It is about 20 km from the regional center Dumaguete, close enough for commuting, and also gets quite a few retirees.
The snorkeling off the beach is just a sandy sea-bed, few fish. Need a boat to reach good snorkeling here. However, some artificial reef just off the GRACEY Resort's beach, might be the best snorkel-zone if on foot...
Most of the accommodation in and around the town is dive resorts. These can be booked directly or through dive shops or travel agents in Dumaguete.
