Covering more than 5000 sq. km, the Nanda Devi National Park is an ecological gem, found 19 km away from Joshimath by trek. It was created around the area of the second highest Indian mountain peak, Nanda Devi (7817 meters). The rich biosphere, spectacular views and high altitude make it stand out from most other national parks. The park is home to a whopping 80 wildlife species, including bears, the fabled snow leopard and musk deer, as well as 300 plant species. In the 1980s the park was recognized as a UNESCO World Heritage site. The park is shut from November to April due to the extreme winters. The weather in Nanda Devi National Park is at it finest in summer, which makes it the best time to visit.

The winter season here is normally extremely cold, with temperatures dropping to sub-zero levels. The Nanda Devi National Park is shut off to the public for this six month duration due to excessive snowfall and lack of visibility. The flora and fauna in the area also tends to go into hibernation during this period and the trekking path from Joshimath is unscalable. It is strongly recommended that visitors venture elsewhere during this period as no outdoor activities will be possible. 

From June to August is when the national park receives moderate to heavy rainfall. Although this beautifies the entire surrounding vegetation, it also brings with it the additional dangers of flooding and landslides in the area and especially on the trekking path to the park. Visitors are strongly advised to travel wih caution during this season. However, if the weather holds up, visitors will be treated to some breathtaking views of the park and Himalayas as well as the lush flora on offer. 

This is the best time to visit the national park, with the warm weather and clear skies making for an ideal climate. A trek to the jungle can be truly enjoyed during this period and visitors can additionally have incredible wildlife sightings during the summer. The summer evenings bring with them a cool breeze that is in ideal contrast with the hotter days. Most of the rare species tend to come out of hiding at the conclusion of winter and search for nearby watering holes to quench their thirst. Nearly 80 animal species and over 300 plant species are on offer for lucky visitors. It is highly recommended to check out the national park during this part of the year.
