What Are The Best Water-Based Activities In Koh Tao
1. Scuba Diving
Scuba diving is one of the most popular things to do on the island. Clear water and calm seas, especially from March to September, give good conditions for learning and fun dives. People can visit shallow coral areas, deeper rock formations, and even shipwrecks. It is important to book with certified schools that teach and follow safe diving practices.
2. Snorkelling
For tourists asking “what to do in Koh Tao,” snorkelling lets you enjoy adventure activities without needing a full dive course. Sheltered bays reveal coral, tropical fish, turtles, and sharks near the surface. You can also join easy guided boat trips that hit multiple spots in a day, blending swimming, boat relaxation, and beach time.
3. Freediving and Underwater Exploration
Freediving has become popular among travellers who want to experience the underwater world. Just like with scuba diving, you can choose a trained, professional instructor and join a small group when you go for underwater exploration. Courses usually focus on relaxation, safety, and depth progression. This ensures that your freediving experience stays within safe limits while still offering the thrill many travellers seek from Koh Tao adventure activities.
4. Kayaking and Stand-Up Paddleboarding
Kayaking and stand-up paddleboarding are calm, easy ways to enjoy the sea around Koh Tao. You can move along the coast at your own pace and enjoy views of bays and beaches. On days with calm water, paddling is a nice break from diving or snorkelling. You can rent equipment for a few hours and stop to swim and explore.
