Snorkeling Tour Koh Tan & Koh Mudsum

Escape your busy day by snorkeling and swimming in the clear water around Koh Tan and Koh Mudsum. This snorkeling site varied from waist-deep to the coral reefs level is the best place for both beginners and professional snorkelers. A few hundred metres away from the southwestern coast of Koh Samui is the location of Koh Tan. You can easily get there by exciting long tail boat. This small island with its beauty of untouched nature has its reputation for its coral and underwater life. Various fish species can be found around the protected reefs including giant clams and fan corals. Take the trip for snorkeling and strolling along the wooden platform on the fine beaches to see the beautiful view of mangrove forests. Koh Tan is also well known as the island without dog since all dogs that have been brought to this island gone crazy quickly, but luckily this fate does not share to the people living on the island. Away from Koh Tan to the south, opposite the Laem Sor Chedi beach, there’s Koh Mudsum. This island is popular among Thai local groups for picnic and some college students for camping and singing along campfires.
