The speedboat cuts a low white wake as the islands rise from the Andaman like granite sentries, their rounded boulders striking the horizon. Salt air and engine hum set the pace; within an hour the water brightens from turquoise to the clear blue that made the Similan Islands famous.

Bring reef-safe sunscreen
Apply at the pier and reapply after snorkeling to protect coral and avoid fines for using prohibited lotions.
Prepare for rough seas outside high season
The west side of the islands is exposed to the southwest monsoon (mid-May–Oct); take motion-sickness meds if you’re prone to seasickness.
Wear sturdy water shoes
Rocky beach entries and hot sand at Princess Bay make protective footwear useful for short walks and boarding.
Charge and waterproof electronics
Bring a small waterproof bag or pouch for phones and keys — photo opportunities on the Sailing Rock are frequent and brief.
Reef-safe sunscreen
Protects coral and skin during prolonged sun exposure on the boat and at shallow snorkel sites.
