The Best Beaches for Snorkelling in Koh Phangan

A naturalist comes to Koh Phangan for a different island than the one the posters sell. Forget the full moon for a moment, because the quieter truth of this place is a northwest coast of sheltered bays and fringing reef where the snorkelling is genuinely good, far from the noise of the party beaches in the south. Choose your shore with care and the Gulf of Thailand here rewards you with clear, warm water and living coral within a short swim of the sand.

The jewel is Koh Ma, a small island joined to the beach of Haad Mae Haad by a pale sandbar at the northwest tip, set inside a protected marine area. You walk in from the sand and follow the reef around the islet, drifting over hard and soft coral with parrotfish, butterflyfish, wrasse and the flicker of damselfish among the heads. It is the best shore snorkel on the island by a clear margin, and on a calm morning before the wind it is a quiet wonder.

The same coast holds more. Haad Salad and Haad Yao, just south of Mae Haad, have their own fringing reef within an easy swim, and the sheltered northern bays around Chaloklum and the little cove of Haad Khom keep clearer water than the exposed and crowded south. These are working, lived in beaches rather than untouched ones, but the reef is real and the snorkelling honest, which is more than the famous southern sands can say.

Wherever you go in, tread lightly, because reef this far north in the Gulf is precious and slow to heal. Wear a rash vest or a reef safe sunscreen rather than the chemical kind, never touch, stand on or kick the coral, and keep your distance from the turtles and fish. We have ranked the six best below, each linked to its full guide, with the living northwest reefs at the top and the party beach kept honestly in its place.

The honest read is that the beach Koh Phangan is famous for is the worst one for snorkelling. Haad Rin and the southern party coast are about the scene, not the sea floor, so a snorkeller who follows the crowds will be let down. The reef lives on the opposite corner of the island, in the sheltered northwest, and the short trip up there is the single best thing a snorkeller can do here.

Koh Ma off Haad Mae Haad is the answer for almost everyone, a protected reef you can reach on foot from the sand, with the most coral and the most fish on the island. Spread your days along the same coast to Haad Salad and Haad Yao for more fringing reef, and to the quiet northern coves of Haad Khom and the bays near Chaloklum for clear, calm water with hardly anyone about. A boat trip to the Ang Thong marine park or the dive site at Sail Rock adds deeper water, but the island's own reef is reward enough.

Timing and care decide your day. The calmest, clearest water generally runs from around February to September, while the late year monsoon stirs the sea and drops visibility, and mornings before the wind are always best. The reef here is fragile and slowly recovering, so wear a rash vest or reef safe sunscreen, never touch or stand on the coral, give the turtles and fish room, and treat the sea and tide as typical rather than guaranteed, checking the day before you go in.

The best snorkelling beaches here are simple, reef fringed bays, so many travellers pair a morning over the coral with a comfortable base for the afternoon. The beach clubs, bar terraces and seafront kitchens along the west and northwest coast rent loungers, shade and a meal behind calm water, which makes an easy spot to dry off between snorkels. Operators, opening hours and any minimum spend vary with the season, so we keep the live list on the directory.
