Best Snorkeling Spots for Non-Divers
Japanese Gardens
Located between Koh Tao and Koh Nang Yuan, Japanese Gardens is arguably the best snorkeling site in the Gulf of Thailand. The shallow reef (1–5 metres) is covered in beautiful hard and soft corals.
You'll see clownfish, angelfish, pufferfish, and if you're lucky, a sea turtle cruising by. Accessible by longtail boat from Mae Haad (about 200 THB round trip).
Shark Bay (Thian Og Bay)
Despite the name, the sharks here are harmless blacktip reef sharks — usually juveniles about 1 metre long. They patrol the shallow sandy areas and are incredible to watch from the surface.
The bay is accessible by a trail from the south of the island. There's a small entrance fee (100 THB) at the viewpoint resort above.
Mango Bay
On the north coast, Mango Bay offers excellent snorkeling over a rocky reef with great visibility. It's a favourite stop on snorkeling day trips.
The coral is in great condition and you'll spot groupers, moray eels, and schools of fusiliers. Best visited on a calm day.
Aow Leuk
A beautiful east-coast bay with a gently sloping sandy bottom and healthy reef on both sides. It's one of the most beginner-friendly snorkeling spots.
There's a small beach bar where you can rent gear and grab a cold drink between swims. Entry fee is usually 50 THB or free if you buy food/drinks.
