About Unseen Tours Koh Tao
Unseen Tours Koh Tao is a boat-trip and snorkelling operator based on the island, specialising in journeys both around Koh Tao itself and out to the dramatic Ang Thong National Marine Park, a cluster of more than forty limestone islands in the Gulf of Thailand. All departures leave from Koh Tao, making it a convenient choice for visitors wanting island-hopping adventures without relocating.
The company runs full-day snorkelling trips around Koh Tao and Koh Nang Yuan, private sunset cruises, and multi-day overnight expeditions to Ang Thong by speedboat, with kayaking included at many stops. Snorkel gear, food, drinks and guides are provided on board, and trips cater to families, couples and groups, with shared and fully private charter options.
Unseen Tours stands out for combining local Koh Tao departures with proper Ang Thong overnight itineraries, a pairing many operators run only from Koh Samui. That, plus private charters and kayak-and-snorkel combinations, makes it a flexible pick for travellers wanting more than a standard day trip.
