Ludao
A short distance offshore from Taitung, Green Island is surrounded by beautiful coral reefs that make it a snorkelers' paradise. On the island itself, most of the scenic spots are linked by the 16.3-kilometer round-the-is-land concrete highway. These include the Green Island Lighthouse, Green Island Park, General Rock, Gateway Rock, Guanyin Cave, Youzi Lake, Pekinese Dog Rocks, Sleeping Beauty Rock, Sail Cape, Black Ghost Cave, and the rare Zhaori Saltwater hot spring. Bathing in the spring under the stars at night is especially popular with visitors.
Green Island Visitor Center
Located directly opposite the airport exit, the visitor center houses a permanent display of geological samples, information about local flora and fauna, underwater photography and a multimedia conference room, where films are regularly shown
