Dolpa is often called "The Hidden Heaven," "Mysterious Dolpa," "Dream Land Dolpa," and "Exciting Dolpa." Dolpa is the largest district of Nepal (area: 7932 sq.km.). Shey-Phoksundo, the largest national park of Nepal, is in this district. Established about 21 years ago, the national park spreads over an area of 3550 sq. km. Considering the decent and balanced combination of natural, social, cutural and geographical aspects, the park has been proposed by His Majesty's Government to be enlisted into the inventory of the world heritage.

Situated in the park area is Phoksundo Lake. It is the deepest lake of Nepal (about 650m) and the second largest from the viewpoing of area. This lake is often called the "Lake of Mystery". Located at an altitude of 3600 meters from the sea level, the lake does not contain any living creatures. Some experts attribute this to the low temperature. The lake covers an area of 7.6 sq. km. Needless to say, the clear, blue water-mass of the lake is alluring to any tourist reaching the site; the surrounding landscape and vegetation is equally fascinating. The wonderful cliffs, various types of layered rocks, gorges, hills and the Suligad River pouring out of the lake at its southern border are very attractive. The river changes into the 167 m high Suligad Fall afterwards. This fall is situated at the highest altitude in Nepal, according to Dolpa DDC.
