Most Similan Islands speedboats stop at two main snorkeling sites during a day trip. These locations offer clear water and abundant marine life.
Day trips from Khao Lak or Phuket usually schedule 45-minute snorkeling sessions near Koh Ba Ngu (Island No. 9) and Koh Payu (Island No. 7). You will view underwater granite boulders and coral reefs directly from the boat.
You must apply reef-safe sunscreen before swimming. The national park strictly bans formulas containing oxybenzone, octinoxate, 4-MBC, or butylparaben.
