Overview and Location
Eravikulam National Park is one of Kerala’s most renowned high-altitude protected areas, located near Munnar in the Idukki district of the Western Ghats. Spanning an area of 97 km², it was established in 1978 to conserve the endangered Nilgiri Tahr (Nilgiritragus hylocrius), a mountain goat species endemic to the Western Ghats.
The park forms part of the Western Ghats UNESCO World Heritage Site and is known for its rolling hills, grasslands, and shola forests, making it a unique biodiversity hotspot in southern India.
Landscape and Geography
Eravikulam lies at an elevation ranging from 1,520 m to 2,695 m above sea level, with Anamudi Peak, the highest peak in South India (2,695 m), situated within the park’s boundaries. The terrain consists of montane grasslands interspersed with shola forests, which are stunted tropical evergreen forests typical of high-altitude Western Ghats.
These ecosystems create a patchwork landscape that is both scenic and ecologically significant. Streams and rivulets originating in the park feed into the Periyar and Muthirappuzha rivers, supporting downstream agriculture and hydropower projects.
Flora and Vegetation
The park’s flora is dominated by shola-grassland complexes, which include high-altitude grasses, shrubs, and endemic flowering plants such as Strobilanthes kunthiana (Neelakurinji), which blooms spectacularly once every 12 years, covering the hillsides in blue.
The shola forests harbor rare endemic tree species, ferns, orchids, and medicinal plants, contributing to the park’s status as a genetic reservoir for high-altitude flora of the Western Ghats.
Fauna and Wildlife
Eravikulam is primarily famous for the Nilgiri Tahr, with a population exceeding 1,000 individuals, making it one of the largest protected populations of this species in India. Other notable mammals include elephants, leopards, wild dogs (dholes), gaur, sambar deer, and bonnet macaques.
Birdwatchers can observe species such as the Malabar whistling thrush, Nilgiri flycatcher, black-and-orange flycatcher, and great hornbill. Reptiles and amphibians are also present, adapted to the high-altitude environment.
Tourism and Activities
The park is a popular eco-tourism destination, attracting nature enthusiasts, photographers, and trekkers. Entry to the park is regulated to protect sensitive wildlife habitats, with jeep rides and guided treks available in designated zones.
The Neelakurinji bloom season, which occurs once every 12 years, is a major attraction, drawing thousands of tourists to witness the breathtaking blue landscapes. Trekking along the rolling hills, observing the Nilgiri Tahr, and exploring the shola forests are key highlights of a visit.
Conservation Significance
Eravikulam National Park plays a critical role in the conservation of high-altitude ecosystems of the Western Ghats. The park is part of the Nilgiri Biosphere Reserve, which protects endemic and endangered species while maintaining ecological balance.
Strict regulations on grazing, tourism, and poaching help safeguard the Nilgiri Tahr and other sensitive species. The park also serves as a research hub for high-altitude flora and fauna studies.
Best Time to Visit
The ideal time to visit Eravikulam National Park is October to June, avoiding the heavy monsoon season (July–September). The Neelakurinji flowering occurs once every 12 years, with the next bloom attracting large-scale tourism, making that period exceptionally popular.
