Similan Islands Snorkeling Day Trip from Khao Lak — Speedboat to Islands 4–9
A fast-paced, full-day speedboat trip from Khao Lak to the Similan Islands that pairs powder beaches with world-class snorkeling sites. Expect crystal-clear water, vibrant coral slopes, and a climbable viewpoint at Sailing Rock.
The Experience
Before You Go
Bring reef-safe sunscreen
Carry and apply only reef-safe sunscreen to protect coral and avoid fines; reapply after swimming.
Prevent seasickness
If you’re prone to motion sickness, take medication or use acupressure bands before departure—the speedboat can be bouncy.
Fit your snorkel gear
Test and adjust your mask on land so it seals well; a leaky mask quickly ruins a snorkeling session.
Respect the reef
Do not touch, stand on, or feed marine life; anchors and boots damage coral—follow guides’ instructions.

Conservation Note
The islands are a marine national park with seasonal closures to aid reef recovery—use reef-safe products, avoid touching coral and follow ranger guidance to reduce impact.
The Similan Islands were designated Thailand’s ninth national park in the 1980s; the name derives from the Malay word for nine and reflects the archipelago’s traditional maritime ties.
