The Experience

The catamaran slips away from Khao Lak at first light, the Andaman Sea opening like a cool promise. Salted wind fills the sails and the islands—granite domes rising from turquoise water—loom ahead. Onboard, breakfast and briefing ease you into the day: masks checked, life jackets adjusted, plans made for reefs and viewpoints.

Before You Go

Bring reef-safe sunscreen

Use only reef-safe sunscreen to protect coral and apply before boarding to avoid contaminating the water.

Mask fit matters

Test and adjust your snorkel mask during briefing; a good seal prevents leaks and frustration in the water.

Prevent seasickness

If you get motion-sick, take medication 30–60 minutes before departure and sit midship where motion is reduced.

Respect marine life

Do not touch or stand on coral; maintain distance from turtles and feeding fish to avoid stressing wildlife.

Conservation Note

The park uses seasonal closures and visitor rules to reduce reef stress; visitors should use reef-safe products, avoid touching coral, and follow guide instructions to limit impact.

The Similan Islands were designated a national park to protect their unique marine habitats and iconic granite islands, becoming a cornerstone of Thailand’s marine conservation efforts.
