Koh Nang Yuan, with its three small, green islands connected by fine strips of white sand, is a picture postcard setting. On the island lies the Japanese Garden, a small bay with crystal-clear waters, lined with granite rocks that have been polished by the water. In the water you will see clownfish in their anemones, butterflyfish, clams and shoals of parrotfish, but the coral bed are damaged in some places.

How to get to Koh Nang Yuan for snorkeling?

Koh Nang Yuan is a few hundred yards off the coast of Koh Tao. It costs around 150 bahts per person for a one-way trip to Sai Ree Beach (minimum 2 people) in a long-tail boat. An admission fee of 100 bahts per adult (50 bahts for children) is charged on site. A large number of snorkeling excursions are organized in Koh Tao, including a stop at this spot, as well as others nearby (Tanote Bay, Shark Bay, etc.). For an excursion including stops at 3 or 4 spots, the price is between 1 000 and 1 200 bahts per person.

Koh Nang Yuan snorkeling tips

Go straight ahead from the beach, crossing a few dozen yards of sandy sea bed, sometimes covered with pieces of dead coral (↕3-10ft/1-2m). Shoals of parrotfish and spinefoot feed tirelessly in this area, raising clouds of white sand. Move on further to reach the coral areas (↕6-12ft/2-4m). Soon you will see some heads of porous coral, incrusted with multi-colored giant clams and Christmas tree worms. Look out for the large green and purple sea anemones attached to the sea bed. Each one is the home of pink skunk clownfish, which will keep a worried eye on you if you come too close, as they nestle in the tentacles of their hosts. In the Japanese Garden, the sea bed is in poor condition, which is the case for almost all the snorkeling spots nearby.

This spot is a great favorite with diving clubs, which come here for first-time scuba dive. Make yourself visible if you plan to go more than a few hundred yards from the beach.

It is so easy to go to Koh Nang Yuan for the day that it is not essential to have accommodation there. If you wish, you can rent a bungalow at Nangyuan Island Dive Resort for a much higher price than at Ko Tao, however. There is a restaurant and a bar near the beach.
