The Valley of Flowers National Park is located in the upper reaches of Uttarakhand and is situated at altitudes ranging from about 3352 to 3658 meters above sea level. This altitude range falls squarely within the temperate alpine zone of the Himalayas, characterized by alpine meadows above the tree line. Among the given options, it is the park that lies predominantly, if not completely, within this ecological zone, known for its vast diversity of alpine flora. The other parks are located at lower altitudes or span a wider range of ecological zones.
Valley of Flowers is famous for its alpine meadows and high-altitude location in the temperate alpine zone.
Manas National Park is in Assam, largely subtropical. Namdapha National Park in Arunachal Pradesh has a range from tropical to alpine, but it’s not *completely* alpine. Neora Valley National Park in West Bengal covers subtropical to temperate forests but does not primarily lie in the high alpine zone. The Valley of Flowers, along with the adjacent Nanda Devi National Park, is a UNESCO World Heritage Site recognized for its unique alpine flora and fauna.
