Koh Nang Yuan is a short boat ride away from Koh Tao. It's known for its picturesque beaches with crystal-clear waters, white sand, and vibrant coral reefs. There is a famous viewpoint here that you can hike to where you get an amazing view over the island below. It takes around 20 minutes to walk up.

The island can get very crowded as there is not that much sand space, so try to come early on the first boat out.
