A. Koh Phangan

Koh Phangan lies off mainland Thailand in the gulf of Thailand, within Surat Thani province. The island is known for its beaches and tropical scenery, with limited direct diving on the coast compared to nearby dive hubs. Existing dive centers typically focus on offshore day trips from Thong Sala and Chaloklum, catering to recreational divers with reef slopes, shallow coral gardens, and occasional macro life. While Koh Phangan offers a scenic base for general travel, regional diving within this administrative area is modest and often pursued as part of wider Gulf of Thailand itineraries rather than as a single-destination diving region.
