Daytime stroll at Ao Prao Beach, Ao Phrao Beach or Phaw Bay, Koh Samet, Thailand. Ao Prao is basically the only beach on the west coast of Koh Samet island. A nice beach to watch the sun set in Samet.. The road is blocked if you aren’t staying at the resorts but you can park your bike at the entrance and do a short walk down the hill to the beach. The beach was well cleaned besides from some washed up trash at the northern end, but that could have happened over night.
