- Do not expect boat-tour reefs; shore snorkeling is modest but fun
The story
You do not need a boat tour to snorkel on Koh Samui: several east-coast spots have reef and fish directly off the beach, free with your own gear. Coral Cove (Ao Thian), between Chaweng and Lamai, is described by a 2026 snorkeling guide as the island's best shore-access snorkeling: rocky outcrops on both sides of a small bay with reef fish, sea urchins and occasional moray eels. Silver Beach (Thong Takhian) has good snorkeling along the granite boulders at both ends of a calm, sheltered cove.

Choeng Mon in the northeast has modest reef near its rocky headlands. The main beaches (Chaweng, Lamai) have little reef from shore. Conditions are best in the morning and in the calm season (roughly December to April); visibility drops when seas are rough.
Bring or buy your own mask, snorkel and fins; reef-safe sunscreen and water shoes help. Never snorkel alone, watch for boats and sea urchins, and do not touch coral.
