Snorkeling Safety Tips

Before you dive in, it’s essential to keep these safety tips in mind:

  • Wear a life jacket: No matter your swimming abilities, a life jacket provides essential buoyancy and aids in conserving energy.
  • Don’t touch the coral: Coral is delicate, and touching can damage it; also, remember some coral species may have sharp edges or stinging cells.
  • Maintain a safe distance from marine life: Getting too close can put both you and the animal at risk; use your snorkel to observe from a distance.
  • Check the weather: Make sure the conditions are suitable for snorkeling before diving in.

By following these safety tips, you’ll minimize potential risks and ensure a safe and enjoyable snorkeling experience in Koh Tao.
