Salt air and sunlight hit first — the longtail slips away from the pier and the Andaman Sea opens, daring you to dive in. In four hours you’ll hop between three Khai islets, each a compact stage: a powdery beach for padding barefoot, a shallow reef alive with curious fish, and a quiet cove that holds its own small drama of waves and current.

History
The Khai islets are small coral-limestone outcrops used historically as fishing and temporary landing spots by local communities rather than permanent settlements.
Conservation
These reefs are fragile; avoid touching or standing on coral, use reef-safe sunscreen, and follow guide instructions to minimize impact.

Bring a waterproof phone case
Waves and splashes are constant; a water-tight pouch protects your camera and valuables while you snorkel or lounge on deck.
Use reef-safe sunscreen
Sunscreen chemicals harm corals — choose mineral-based sunblock and reapply after swimming to protect skin and reef.
Wear reef shoes
Shallow reef and rocky shorelines can be sharp; lightweight water shoes protect feet when entering and exiting the water.
Pick morning departures
Calmer seas and clearer water typically occur in the morning, improving visibility and making snorkeling easier.
Swimsuit and quick-dry top
Comfortable swimwear and a rash guard protect from sun and chafe while snorkeling.
