Koh Tao and Koh Nang Yuan are among the most popular snorkeling day trips from Koh Samui. Koh Tao is known for clear water and coral reefs, while Koh Nang Yuan is famous for its white sandbar, shallow water and hilltop viewpoint.
Most trips combine snorkeling around Koh Tao with time on Koh Nang Yuan. The main choice is usually how you want to travel. Speedboat tours are designed for a faster point-to-point journey and multiple snorkeling stops, while high-speed catamaran trips offer a different travel style and schedule.
If you prefer a more flexible day, private speedboat charters are also available. A private charter is a better fit for couples, families or small groups who want more control over the departure time, snorkeling stops and overall pace of the trip.
