The Experience
Before You Go
Bring reef‑safe sunscreen
Sunscreen is required by park rules in many parts and protects coral — choose reef-safe formulations and reapply after swimming.
Prep for seasickness
Open-water crossings can be choppy; take anti-nausea meds or wear pressure bands if you’re susceptible.
Use the right footwear
Water shoes or sandals with grip help on hot sand and slippery granite boulders when exploring shorelines.
Book during park season
The Similan National Park operates roughly Oct–May; trips outside that window are not available due to monsoon closures.

Conservation Note
Visitor numbers and access are controlled by park regulations and seasonal closures to reduce reef stress; using reef‑safe products and not touching coral helps protect the ecosystem.
The Similan Islands were designated a national park in the early 1980s to protect one of the Andaman Sea’s most diverse reef systems, shifting local economies toward regulated tourism.
