This Pak Meng Beach in Trang for sure is A hidden gem. I love the quieter places and this for sure is a wonder for me. I had heard of Krabi and Phuket and the Karon from you and this is totally new. I really like it. The only worse thing is the low tides and the non exceptional night life. Apart from all this everything is great. Gibbon sanctuary and aquarium are a bonus to the already great place.
