Ao Bon on Surin Tai is a sheltered coral bay for easy snorkeling.
Ao Bon on Surin Tai is a sheltered coral-bay snorkel site with a shallow reef that starts close to shore. The bay front holds the easiest water, with coral gardens and fish life in a layout that stays simple to read on calm days. It is a strong beginner-friendly choice, but park-season access, weather, and coral-care rules still matter.
