A brisk speedboat run from Phuket delivers three compact islands—Khai Nok, Khai Nui and Khai Nai—for snorkeling, short swims and beach time. Ideal as a half-day escape, the tour mixes clear-water reef views with easy beach access and hotel transfers.

The engine thumps, the spray pushes back your hair and the mainland shrinks until three tiny white crescents appear on the horizon: Khai Nok, Khai Nui and Khai Nai. The speedboat cuts across Andaman blue, and the islands—bare, low and ringed with coral—seem to dare you to trade Phuket’s bustle for a day of salt, sun and quick adrenalin.

Use reef-safe sunscreen
Apply biodegradable sunscreen before boarding and reapply only where permitted to protect coral and marine life.
Bring a lightweight waterproof bag
Keep valuables and a dry change of clothes secure—pier facilities are basic and boats can spray saltwater.
Prepare for motion
If you’re prone to seasickness, take medication 30–60 minutes before departure; trips cross open water and conditions can change.
Respect wildlife and local etiquette
Do not touch coral or chase fish; feeding cats or wildlife disrupts local behavior and is discouraged.

Protects skin while minimizing harm to coral and marine life.
Lightweight swim cover-up or rash guard
Shields from sun on the boat and adds warmth after exiting the water.
Waterproof phone case or dry bag
