Read the full experience

The day begins before sunrise on the Khao Lak shoreline: guides from SeaStar Andaman check masks and life jackets while a ribbon of light slides over the Andaman Sea. Within an hour on a first-class speedboat the islands draw near, rock faces rising from blue water like bookends to a thriving underwater world. Currents here push and pull, nudging you along reefs thick with staghorn, brain coral and schools of parrotfish.

Adventure tips

Book in-season (Oct–May)The Similan National Park is closed during monsoon months; schedule between 15 Oct and 15 May for reliable operations and calmer seas.

Bring reef-safe sunscreenOnly use biodegradable, reef-safe sunscreen to protect corals and follow guide instructions to avoid physical contact with reefs.

Wear snug snorkel gearA well-fitting mask and fins improve visibility and reduce fatigue during multiple snorkel stops; staff supply gear but bring your own if possible.

Prepare for a long dayThis is a 10-hour excursion with early pickup—pack snacks, motion-sickness meds if needed, and a waterproof bag for valuables.

Recommended gear

Snorkel mask and fins: Improves comfort and maneuverability during repeated reef swims; rentals available but fit matters.
Reef-safe sunscreen: Protects skin from tropical sun while keeping coral-safe ingredients in the water.
Waterproof dry bag: Keeps phone, passport copy and a light layer dry on deck during transit.
Light long-sleeve UV shirt: Sun protection when not in the water—quick-dry material helps on windy boat rides.
