Koh Tachai is an island in the world famous Similan Islands. It is an idyllic location in the Andaman Sea with white sandy beaches and azure crystal clear water. The island is located 40km due west from Koh Phra Thong. Blue Guru Diving is the closest PADI dive centre to this scuba diving mecca. It is about 570 km south of Bangkok and 130 km north of Phuket.
Koh Tachai is unique in Thai waters in that it holds equal appeal for both divers and snorkelers. Scuba divers have the opportunity to observe sharks/mantas off Koh Tachai's pinnacle whilst snorkelers enjoy the calm shallow bay. The beaches at Koh Tachai are spectacular with the white sand and clear water. For these reasons it is often referred to as the Maldives of Thailand.
