The Experience

Before You Go

Bring your passport

National park tickets are issued using passport details—have it ready for collection after booking and bring it on the trip.

Use reef-safe sunscreen

Chemical sunscreens damage coral—choose reef-safe sunscreen and apply well before entering the water.

Prepare for a full day

Expect 8–9 hours including hotel transfers—pack water, a towel, and a lightweight cover-up for sun protection.

Manage seasickness proactively

Open, fast rides can be bumpy; take anti-nausea medication beforehand if you’re prone to motion sickness.

Local Knowledge

Hidden Gems

  • Climb the Sailing Rock viewpoint on Koh Similan for angled island views away from the main beach
  • Shade-lined coves on smaller northern islets where morning snorkeling finds calmer water and quieter reefs

Wildlife

  • Green sea turtle
  • Reef fish and occasional dolphins

Conservation Note

The park enforces seasonal closures, limits visitor numbers and requires park tickets; visitors should avoid touching coral, use reef-safe sunscreen, and pack out all trash.

Declared a national park to protect its marine and island ecosystems, the Similan Islands have long supported local fishing communities and now operate under seasonal tourism controls to limit impact.
