The day begins before sunrise at a private pier near Khao Lak, when the boat slips into dark water and the islands appear as pale shapes on the horizon. By the time you reach Donald Duck Bay the ocean has lightened to turquoise; the surf pares away the shore, and the white sand dares you to step in.

History
The Similan Islands have been known to local sea people for generations and were designated a national park in 1982 to protect their marine and island ecosystems.
Conservation
The islands are seasonally closed for monsoon and reef recovery; visitors should use reef‑safe products and follow guide instructions to reduce impacts.

Bring reef‑safe sunscreen
Use mineral-based sunscreen to protect coral and reapply often — the sun and reflection off the water intensify UV exposure.
Prepare for seasickness
Take motion-sickness medication before boarding if you’re prone to nausea; trips include basic remedies but earlier dosing is more effective.
Secure loose items
Bring a dry bag and secure phones and passports; transfers and boarding are quick and boats can be wet and bouncy.
Respect park rules
Do not stand on coral, avoid feeding fish, and follow guide briefings to minimize your impact on the marine environment.
Mask and snorkel
A well-fitting mask improves visibility and comfort during multiple snorkeling stops.
Reef‑safe sunscreen
Protects skin in tropical sun while preventing damage to coral ecosystems.
