Orchid Island is surrounded by coral reefs and features several recommended dive sites.
The coral reefs of the south and the Pescadores Islands are considered good skindiving areas. Sharks and barracudas are rare in the waters around Taiwan. Some of the sites are easily accessible and provide baths, hot tubs and hotel facilities. Lakes, rivers, fish farms and the sea offer mainly unrestricted fishing. Near Taipei there is good fishing at the Tamsui and Hsintien rivers, Green Lake and Shihmen Reservoir.
