Kaeng Krachan National Park

The most extensive national park of Thailand, occupying a largely unexplored area of 2,915 square kilometers (1.7 million rai of land), Kaeng Krachan was declared a national park on 12 June 1981. The park is located 53.5 kilometers from the city and is 3 kilometers beyond Khuean Kaeng Krachan (Kaeng Krachan Dam).

The park covers a reservoir and year round green jungle in the Tanaosri Ranges, which are the origins of many rivers, including Maenam Phetchaburi and Maenam Pranburi. The unexploited, wholesome jungle makes the park rich in flora and fauna. In addition, visitors may spot leopards, tigers and elephants. The 18-level waterfall named Namtok Tho Thip, located approximately 54 kilometers from the Park Office on the Sai Wang Won-Namtok Tho Thip route is worth a visit. There are viewpoints along the route are not only suitable for bird and butterfly watching but also provide magnificent views of misty mountains in the morning.
