History
The Similan Islands became a national park in the early 1980s to protect its reefs and granite islands; the area has long been part of local maritime livelihoods.
Conservation
Strict park rules limit visitor numbers in season and prohibit taking coral; use reef-safe products and avoid standing on reefs to reduce human impact.

Bring a passport photo on your phone
Thai marine authorities require passport ID for park entry — have a digital copy ready to speed check-in.
Wear water shoes
Flip-flops are convenient but water shoes protect against sharp shells and provide traction on wet rocks and ramps.
Use reef-safe sunscreen and a rash guard
Protect skin and coral; long swimwear reduces jellyfish irritation during peak seasons.
Stay with the group while snorkeling
Currents and visibility can change quickly—follow the guide, use a life jacket if uncomfortable, and avoid touching coral.
Reef-safe sunscreen
Protects skin while reducing damage to coral ecosystems.
Water shoes
Protects feet when boarding from beaches and walking rocky trails.
Mask/snorkel (personal)
Included gear is provided, but a well-fitting personal mask improves comfort and visibility.
