Sunset stroll at Ao Noi Na Beach, Koh Samet, Thailand. Ao Noi Na is a very laid back beach in the north of Koh Samet, next toΒ Ao Klang Beach. There is usually a lot less people here than in the more central beaches.The sun sets on the west side of the island, but you can reach it by walking left at the rocks in the north of Ao Noi Na. I was too lazy to that this time though.
