About Three Rocks
Three Rocks is the shallow, beginner-friendly side of the Pottery/Three Rocks pair in Mae Haad Bay. It is a compact rock-pinnacle site with a short swim-through and easy access from the pier. The site works well for training, photography, and night dives, with the shallow profile and sheltered bay doing most of the planning work.
