A breeze off the Andaman carries salt and the hollow clack of the MV KOON1 as it eases away from Khao Lak at first light. Within an hour the shoreline slides into a curve of blue and the Similan Islands—rocky granite isles rising from deep water—appear like scattered giants, their cliffs and white beaches edged with reef.

Wildlife
History
Mu Ko Similan was designated a national park in the early 1980s to protect one of Thailand’s most important coral systems and to regulate tourism.
Conservation
Annual park closures and limited visitor infrastructure help reefs recover from diving pressure; always avoid standing on coral and use mooring points rather than anchors.
Reserve your spot on the Liveaboard Snorkeling Similan 2 Days 1 Night from Khao Lak today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Bring reef‑safe sunscreen
Use mineral or labeled reef‑safe sunscreen to protect coral; apply on board before water entry and reapply after swimming.
Prepare for motion
If you’re prone to seasickness, take medication before boarding and sit midship where motion is least felt.
Respect seasonal closures
The national park is closed May 16–Oct 14—book between mid‑October and April for full access and calmer seas.
Protect your gear
Bring a quick‑dry towel and a dry bag for cameras and phones; salt and spray are constant companions on deck.
Fitted snorkel mask
A comfortable, well‑fitting mask improves visibility and prevents frequent clearing during reef swims.
Reef‑safe sunscreen
Protects skin from UV and prevents bleaching chemicals from reaching corals.
Light windbreaker or fleece
Evenings on deck can be cool after sunset; a thin layer stops spray and wind chill.
Dry bag (5–10L)
Keeps electronics, documents, and spare clothes dry during transfers and snorkeling exits.
