Located on the east coast of Koh Tao, Hin Wong is a large bay surrounded by boulders. There is a lot to see here snorkeling; you could spend an entire day exploring the bay.Several underwater pinnacles are covered in fertile coral, anemones, and many kinds of fish that can be seen. Due to the rock formations, it isn’t easy to walk around Hin Wong Bay, so it’s a good idea to rent a kayak to get around. Go across to the area in front of the beach on the south side of the bay, and it’s one of the best snorkeling spots on Koh Tao. The water here is incredibly clear, and you may be lucky enough to see great schools of sardines being chased by hungry trevally in water less than a metre deep. Another excellent place for snorkeling is a point north of the bay. Again, there is lots of well-preserved coral and abundant marine life. Hin Wong Bay is a quiet getaway; you can get here by road or boat. If you feel like walking, it takes about an hour from the junction at Sairee.
