Morning light slices across the Andaman as a speedboat lifts off from Krabi’s pier, spray tasting of salt and diesel. Within an hour the shoreline fades and the Similan Islands—rounded granite domes rising from deep blue—appear, their beaches blindingly white against reefs that hum with life.

The Similan Islands were designated a national park in the early 1980s to protect exceptional coral reefs and nesting beaches used by local fishermen for generations.
Conservation
Park authorities limit access during monsoon months and collect entry fees for conservation; visitors should avoid touching coral, use reef‑safe sunscreen and pack out waste.

Bring your passport copy
Similan National Park requires passport details for park entry—have a clear photo or photocopy ready before boarding.
Use reef‑safe sunscreen
Apply biodegradable sunscreen and reapply after swimming to protect coral and prevent skin damage in intense equatorial sun.
Prepare for motion and currents
If you’re prone to seasickness or new to open-water snorkeling, take antiemetics and practice breathing calmly; currents can carry you quickly along shallow reefs.
Hydrate and layer up
Bring a refillable water bottle and a light windbreaker for the cooler, spray‑filled return ride.
Reef‑safe sunscreen
Protects your skin and the coral—apply before launch and after each swim.
Personal snorkel mask
Better fit and clarity than rental gear for longer dives into shallow reefs.
Light quick‑dry towel & swimwear
Dries fast between stops and doubles as sun protection on the boat.
Small dry bag
Keeps passport copy, phone and valuables dry on a sprayy speedboat.
