Ko Mattra, Surat Thani

Ko Mattra remains one of southern Thailand’s quieter island escapes, where pristine coral reefs meet untouched beaches just off the Chumphon coast. This small island offers exceptional diving and snorkelling opportunities without the crowds that descend upon more famous destinations. Crystal-clear waters reveal vibrant marine life just meters from shore, making it particularly appealing to underwater enthusiasts seeking unspoiled coral gardens and diverse fish populations.

The island’s main attraction lies beneath the surface, where healthy coral formations create an underwater playground for tropical fish species. Snorkelling directly from the beach reveals parrotfish, angelfish, and schools of colorful reef fish darting between coral branches. Above water, the island features several small sandy beaches perfect for relaxing between diving sessions. The gentle lapping of waves against pristine white sand creates a soothing soundtrack, while coconut palms provide natural shade. Fresh sea breezes carry the clean scent of ocean water, unmarred by development or pollution.

Peace defines the Ko Mattra experience, with an almost meditative quality that comes from genuine isolation. Few visitors make the journey here, creating an intimate connection with nature that feels increasingly rare. The absence of commercial development means you’ll hear only natural sounds – waves, wind through palms, and the occasional splash of fish jumping. This tranquility makes every moment feel precious and unhurried.

Reaching Ko Mattra requires booking a longtail boat or joining a day trip from Chumphon town, with most operators departing from the main pier. The journey takes approximately 45 minutes depending on sea conditions. No accommodation exists on the island, making it strictly a day trip destination. Bring snorkelling gear, sun protection, and drinking water as no facilities are available. Visit during calm weather months for the best underwater visibility and safest boat transfers.
