Tongpan Geopark Introduction
Tongpan Island is located approximately 6 nautical miles from Makung Island. The entire island is surrounded by distinct basaltic columns, which are developed to the fullest extent and are considered the best in Penghu, earning the nickname "Yellowstone Park of Penghu." The island's columnar joints and slab-like fissures are well-developed, originally presenting in hexagonal or pentagonal shapes. Due to severe weathering and erosion, the edges of the rock columns have rounded off, with some basalt columns having weathered into spherical shapes at their tops. On the southwestern coast of Tongpan, there is a coastal erosion platform featuring concentric lava outlets formed by basaltic magma eruptions. The central rock mass, which rises like a lotus pedestal, is known as "Lotus Seat" and is revealed as the tide rises and falls, showcasing a very unique topographical landscape in Penghu. The "Boran Coffee Drum Segment" advertisement prominently features the entire silhouette of Tongpan Island at the beginning, where the powerful drum sounds and magnificent basalt formations create an astonishing impact. The basalt columns of Tongpan are a popular subject for many travel programs and advertisements, and the imposing columnar joints are the most representative unique element of Penghu.
