At the southern end of Lamai Bay are phallic rock formations called Hin Ta Hin Yai. A path connects the three waterfalls, called Namtok Hin Lat, Namtok Lat Wanon, and Namtok Na Muang, from west to south. The waterfalls are best visited during rainy season. Elephant riding is an interesting activity at the Na Muang waterfall.
