With its white sand, coconut palm and translucent waters, Sai Nuan is one of Koh Tao’s nicest beaches. The beach, located not far from the main pier of Mae Haad, is decent sized and very secluded yet, and offers a peaceful tropical atmosphere. It also shelters one of the best snorkeling spots of the island, the coral and fish congregating on and around the rocks spread along the shore.

How to get to Sai Nuan Beach for snorkeling?

To get to Sai Nuan Beach, ride south from the main pier at Mae Haad town. Do not go up to the main road, but head directly south along the little roads along the beach. It will open up after a bit. A parking is located at the end of the road. Next to the roundabout, you will see a sign pointing to a jungle path headed south saying “Sai Nuan Beach 10 min.” It is a really easy and beautiful jungle walk through the little bungalows of the resort at the beginning. The entire path is well marked. Much of it is a boardwalk with great sea views all along the path until you get to the small staircase heading down to Sai Nuan Beach. You can also hail a long tail boat taxi on the beach at Mae Haad and travel by water for 200-300 baht, depending on the captain.

Sai Nuan Beach snorkeling tips

Much of the seabed is flat with an occasional rock protruding here or there with coral (essentially tabular and staghorn coral) growing all over the rocks. Snorkel around the rocks located on the South end of the beach. During your exploration, you may spot numerous fish species, including the elegant moon wrasse, the bright yellow Hong Kong butterflyfish, several species of parrotfish and rabbitfish, but also the colorful redbreasted wrasse.

If you want to try to spot a blacktip reef shark, reach the deeper area, a few dozen meters from the beach, but watch for long tail boats crossing in the area.
