A day trip to Koh Tao and Koh Nang Yuan is one of the Gulf's signature experiences — pairing world-class snorkelling in clear, fish-filled water with the postcard-famous triple-island sandbar viewpoint on Koh Nang Yuan. Reached by speedboat from Koh Samui (via Koh Phangan), it is a full-day showpiece that sells itself on the photos alone. As a Thailand DMC for travel agents, Explera books the speedboat, snorkel stops and island fees so the day runs seamlessly.

Frequently asked questions
Where are Koh Tao and Koh Nang Yuan?
They sit in the Gulf of Thailand north of Koh Phangan, reached by speedboat from Koh Samui. Koh Nang Yuan is a tiny cluster of three islets joined by a sandbar, just off Koh Tao.
Is the snorkelling suitable for beginners?
Yes — the bays are sheltered and clear, with gear and guidance provided, so first-time snorkellers are comfortable while keen snorkellers still get excellent reef life.
How long is the day?
It is a full day with an early start, including the boat crossing, several snorkel stops and time on Nang Yuan. We build in the timings so clients are not rushed.
Who is it best for?
Active couples, families with older children and groups who want a scenic, in-the-water day. Those wanting a slower pace may prefer a closer Samui island tour.
