Tongpan Geopark Introduction
Tungkang Island is located about 6 nautical miles from Magong Island. The entire island is surrounded by distinctly patterned basalt columns, which are well-developed and considered the best in Penghu, earning it the nickname "Yellowstone of Penghu." The columns on the island exhibit both columnar and plate-like jointing, originally appearing hexagonal or pentagonal. Due to severe weathering and erosion, the edges of the rock pillars have become rounded, and some basalt columns have weathered into spherical shapes at their tops. The southwest coast of Tungkang features a wave-eroded platform with concentric lava outlets formed by basalt magma eruptions. The central uplifted rock resembles a lotus platform, known as the "Lotus Seat," which is revealed and concealed with the ebb and flow of the tides, showcasing a unique geological landscape in Penghu. The scenic spot "Bolang Coffee - Drumming Edition" prominently features Tungkang Island's silhouette at the beginning of the advertisement, with powerful drum sounds and magnificent basalt formations that leave a profound impact. The basalt columns of Tungkang Island serve as a subject for many travel programs and advertisements, and their grandeur epitomizes the unique elements of Penghu.
