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.
Many visitors come for the fine scuba diving and snorkelling; the town is a diving resort in its own right and a jumping-off spot for boat trips to nearby Apo Island.
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.
There is a coastal highway connecting to Dumaguete to the north, and Zamboanguita and Siaton to the south, with bus and jeepney services to any of those.
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.
