Valley of Flowers National Park

Location, Size, and Life at 3,500 Metres

The Valley of Flowers National Park lies in Chamoli district, Uttarakhand. It sits at 3,352 to 3,658 metres, well above the tree line. The valley covers 87.5 sq km. It is roughly 8 km long and 2 km wide. It lies in the Pushpawati river valley, inside the Garhwal Himalayas. The park was declared a national park in 1982.

• Its flora: the valley holds about 520 species of flowering plants, including the blue poppy, the Brahma kamal, and the cobra lily.
• A short season: the park opens only from June to October. Snow covers it the rest of the year.
• Its fauna: the park also shelters the Asiatic black bear, snow leopard, and blue sheep, species typical of high-altitude Himalayan habitats.
• Its neighbours: Chamoli district also holds other well-known Himalayan sites, including Badrinath and Hemkund Sahib. Trekkers often combine a visit to the valley with these nearby pilgrimage routes.

Two Parks, One World Heritage Site, Two Different Dates

The valley lies 20 km northwest of Nanda Devi National Park. Together, the two parks form a single UNESCO World Heritage Site. The joint site is named “Nanda Devi and Valley of Flowers National Parks.” But their listing dates are not the same. Nanda Devi was inscribed alone in 1988. The Valley of Flowers joined only in 2005. Exam questions sometimes test whether candidates confuse these two separate years.

• One biosphere reserve: both parks also sit inside the wider Nanda Devi Biosphere Reserve, forming its two core zones.
• A recurring pattern: this split-access style, one open zone and one closed core zone, also appears at other joint Himalayan biosphere reserves.

How the Valley Got Its Modern Name

British mountaineer Frank Smythe gave the valley its modern English name in 1931. He stumbled upon it while descending from an expedition to Mount Kamet. Eric Shipton and R.L. Holdsworth were with him on that descent. Smythe returned in 1939, to collect seeds and bulbs of the valley’s alpine plants. He wrote about the valley in a 1938 book, which made it popular among Western readers.

A Botanist’s Fatal Fall

Joan Margaret Legge was a botanist from London’s Royal Botanic Gardens, Kew. She travelled to the valley in 1939, the same year Smythe returned for seeds. Legge fell to her death while collecting plant specimens on the valley’s rocky slopes. She is buried in the valley she had come to study. A small memorial plaque near the valley entrance still marks her death. Five plant species found here are globally threatened, and grow nowhere else in Uttarakhand. Later botanists built on Legge and Smythe’s early plant records, expanding the valley’s known species list.

Trek Rules, and a Question UPSC Has Already Asked

Reaching the valley needs a roughly 17 km trek from the nearest roadhead town. Visitor permits are valid for three days at a time. Flowers bloom in peak density during the monsoon months, from July to September. Entry is allowed only between 7 AM and 2 PM, and all visitors must leave by 5 PM. Overnight camping inside the valley is not allowed. Ghangaria serves as the base village, with the last lodging before the final climb.

Why Isolation Has Protected a Rare Flora

The valley is open only four months a year, and reachable only on foot. This isolation is a big reason its rare, threatened flora has survived largely undisturbed. Rules already ban camping, drones, and single-use plastics inside the park, to limit damage. This same tension, between easier access and ecological pressure, shapes management at other Himalayan biosphere reserves too.

A New 2026 Season, and a Shorter Trek Ahead

The Valley of Flowers National Park reopened for its 2026 season on 1 June, and stays open until 31 October, the only five-month window each year when trekkers can enter at all. Opening day alone drew over a hundred visitors, reflecting steady trekking demand. Separately, officials have approved a new road linking Pulna to Bhyundar village, cutting the trek to roughly 5 km. Today, travellers still reach the valley via Govindghat, Pulna, and Ghangaria, before the final uphill stretch on foot. (Source: Outlook Traveller, June 5, 2026)
