Kaeng Krachan National Park

With an area of 3000-sq-km, this is Thailand's largest national park. Located primarily in the mountains adjacent to Myanmar, and only 40km from Hua Hin, it has lots of rain and an abundance of rainforests and some grassland areas. Animal life includes deer, tigers, gibbons, bears, hornbills, wild elephants and dusky langurs. One of the park's most popular attractions is the eleven-tiered Pa-La-U Yai and Pa-La-U Noi waterfall. This park is difficult to access so the falls are best visited on an organized tour. Several companies is Hua Hin provide tours to the falls and other areas of the park.
