Exploring Nanda Devi and Valley of Flowers National Parks

The park is defined by the Nanda Devi Sanctuary, a glacial basin encircled by a ring of high-altitude peaks. these surrounding mountains reach heights ranging between 6,000 metres and 7,500 metres.

The basin is drained by the Rishi Ganga through the Rishi Ganga Gorge. This geographical feature is described as a steep and almost impassable defile that characterizes the rugged terrain of the region.

The national park is embedded within the larger Nanda Devi Biosphere Reserve, which covers approximately 2,236.74 square kilometres. This area serves as a critical conservation zone in the Himalayas.

Surrounding the UNESCO World Heritage site is a buffer zone encompassing 5,148.57 square kilometres. This expansive area ensures the protection of the core national park environments.

Human exploration of this high-altitude sanctuary dates back to the late 19th century. The first recorded attempt to explore the area was conducted in 1883 by W. W. Graham.

Since its establishment in 1982, the park has transitioned from a local national park to an internationally recognized natural heritage site, gaining its UNESCO status in 1988.

Due to its high elevation and northern location, access to the park is seasonal. The environment is best experienced during the warmer months of the year.

The best time to visit Nanda Devi National Park is from May to October. During this window, the weather conditions are most suitable for navigating the mountainous district of Chamoli Garhwal.
