Rara National Park is a protected area in the Himalayas of Nepal and was established in 1976. Covering an area of 106 km2 (41 sq mi) in the Mugu and Jumla districts, it is the country's smallest national park. Its main feature is Rara Lake at an altitude of 2,990 m (9,810 ft). The park was established to protect the unique flora and fauna of the Humla–Jumla Region of Nepal. The park ranges in elevation from 2,800 m (9,200 ft) to 4,039 m (13,251 ft) at Chuchemara Peak on the southern side of Rara Lake. On the northern side, the peaks of Ruma Kand and Malika Kand frame the alpine freshwater lake, which is the largest lake in Nepal with a surface of 10.8 km2 (4.2 sq mi) and a maximum depth of 167 m (548 ft). It is oval-shaped with an east–west axis, a length of 5 km (3.1 mi) and a width of 3 km (1.9 mi) draining into the Mugu-Karnali River via Nijar Khola. Rara National Park is managed by the Department of National Parks and Wildlife Conservation and protected with the assistance of the Nepal Army.

Rara Lake, also known as Mahendra Lake, is the largest fresh water lake in the Nepalese Himalayas. It is the main feature of Rara National Park, located in Jumla and Mugu Districts of Karnali Province. Rara National Park stretches over 106 km2 (41 sq mi). Rara Lake was included as part of Rara National Park in 1976. In 1976, citizens of the two villages Chapra and Rara were resettled to Nepalgunj. In September 2007, it was declared as a Ramsar site, covering 1,583 ha (6.11 sq mi) including the surrounding wetland. Currently, this area along with the national park is being protected by the Nepali Army. Rara Lake lies at an elevation of 2,975 m (9,760 ft), has a water surface of 10.8 km2 (4.2 sq mi), a maximum depth of 167 m (548 ft), is 5.1 km (3.2 mi) long and 2.7 km (1.7 mi) wide. It drains into the Mugu Karnali River via the Nijar River. Its water quality is characterized by high pH, conductivity and total hardness. It has been classified as oligotrophic as it is slightly polluted. The lake changes its colour up to 5 times a day depending on the climate. Rara Lake is surrounded by thickly forested hills named Chuchemara Danda at 4,087 meters and Murma at 3630m. Behind the hills, the beautiful view of Saipal Mountain of Himalayan Range can be seen from the lake. One revolution of the lake by foot takes almost five hours. During, summer season, birds as far as Siberia can be found migrating to this area.

Dolpo is a high-altitude culturally Tibetan region in the upper part of the Dolpa District of western Nepal, bordered in the north by China. 1/3  Part of the region lies in Shey Phoksundo National Park. The sparse, agro-pastoral population, known as Dolpo in standard Tibetan and Dhol-wa in the local dialect, is connected to the rest of Nepal via Jufal airport, which can be reached in three days by horse.  There are no precise population numbers for the region, with estimates including less than 5,000  and 18,000. The Dolpo are generally adherents of Bon, a religion whose origins predate Buddhism but whose modern form is officially accepted as a fifth school of Tibetan Buddhism. The remote region has preserved its Tibetan culture in relatively pure form, making it attractive to Westerners. Dolpa was the location for the 1999 Oscar-nominated film Himalaya and more recently for the German documentary Dolpo Tulku. In spite of the near inaccessibility of the region and tourism restrictions for the more remote parts, Dolpa is a popular destination for trekking tourism. Dolpo is geologically part of the sedimentary Tibetan-Tethys zone. It is surrounded by Himalayan mountain chains including the Dhaulagiri (8,172 metres (26,811 ft)). These cloud barriers cause a semi-arid climate, with reported annual precipitations of less than 500 millimetres (20 in).

Shey Phoksundo National Park is the largest and only trans-Himalayan national park in Nepal. It was established in 1984 and covers an area of 3,555 km2 (1,373 sq mi) in the districts of Dolpa and Mugu in the Mid-Western Region, Nepal. The protected area ranges in elevation from 2,130 to 6,885 m (6,988 to 22,589 ft). Phoksundo Lake is the park's prominent feature, located at an elevation of 3,612 m (11,850 ft). The park's headquarters are in Palam, Dolpa District. The park's elevation varies from 2,130 m (6,990 ft) in the southeast near Ankhe to 6,883 m (22,582 ft) at the summit of Kanjiroba Himal at the southern edge of the Tibetan plateau.

Phoksundo Lake is an alpine fresh water oligotrophic lake in Nepal's Shey Phoksundo National Park, located at an elevation of 3,611.5 m (11,849 ft) in the Dolpa District. Phoksundo Lake is 494 ha (1.91 sq mi) in size with a water volume of 409,000,000 m3 (1.44×1010 cu ft) and a discharge of 3.715 m3/s (131.2 cu ft/s). In 2004, a survey by the Department of Hydrology and Meteorology measured the maximum depth of the lake at 145 m (476 ft). In 2019, another detailed survey was carried out by the Department of Hydrology and Meteorology, which measured the maximum depth of the lake at 136.20 m (446.9 ft). In September 2007, Phoksundo Lake has been designated a Ramsar site. On the lake' southern end, the village of Ringmo sits on the 30,000- to 40,000-year-old landslide dam that formed the lake. Past the dam, the waters of the lake plunge over a 167 m (548 ft) tall waterfall. There are more than 20 stupas in the southern belt, and one gompa in the eastern side of the lake, where annual prayers and worship are carried out. Traditional Tibetan culture prevails in upper Dolpo; Buddhism and Bon are prevalent in lower Dolpo, including Ringmo village.
