Valley of Flowers National Park

Valley of Flowers National Park blooms at 3,600 meters elevation with over 600 endemic alpine species, including the rare blue poppy. Its 87.5 km² of glacial meadows attract 80% of annual visitors during the August monsoon peak, with a ₹600 entry fee that is cheaper than the average Himalayan park. As a UNESCO World Heritage Site since 2005, it protects 45% more floral endemics than #9 Nagarhole National Park's total plant diversity. The park's short four-month flowering window hosts 15% of India's alpine butterfly species, ranking it as the hardest-to-replace sanctuary on this list.
