The Agasthyamalai Hills also called the Ashambu Hills, lie at the extreme southern end of the Western Ghats mountain range along the western side of South India. There are at least 26 peaks over 1,600 metres (5,200 ft) among these hills. The hills are notable as the habitat for over 2,000 species of medicinal plants and as the abode of the Vedic sage Agasthya, founder of the Siddhar practitioners of Rasayana herbal medicine, who is often depicted holding a mortar and pestle.
These hills contain areas of exceptional natural beauty and aesthetic importance. The hills contain outstanding examples of ecosystems and communities of plants and animals representing significant ecological and biological processes. The area contains important and significant natural habitats for in-situ conservation of biological diversity, including forests containing threatened species of outstanding value to science and conservation.
The hills straddle both sides of the state border Kollam District and Thiruvananthapuram District in Kerala and Tirunelveli District and Kanyakumari District in Tamil Nadu. They are between the Cardamom Hills and Aryankavu Pass at NH-208 about 9° north latitude and the vicinity of the Mahendragiri peak near Kanyakumari at about 8° 20' north latitude. The border between the two States is defined by a jagged high ridge, that runs from north to south and then slightly eastwards, parallel to and about 40 kilometres (25 mi) east of the Kerala shore of the Arabian Sea.
These hills are dominated by the 1,868 metres (6,129 ft) Agasthyamalai peak. The five-peaked mountain Ainthuthalai Pothigai (1,862 metres (6,109 ft)) immediately adjacent to Agasthyamalai, is only a little shorter. Other nearby peaks are Cherumunji Mottai and Naga Pothigai ( ) (1,600 metres (5,200 ft)). There are at least 23 more peaks over 1,600 metres (5,200 ft).
The hills receive up to 5,000 millimetres (200 in) annual rainfall from both the southwest and northeast monsoons and has a very short dry season of January to March. The topography is rugged with many perennial hill streams originating in the tropical rainforests on the upper slopes. These streams merge to form several important rivers. The Kerala rivers Kallada, Achankoil, Vamanapuram, Karamana and Neyyar drain west from these hills. The Thamirabarani River and its tributaries the Ramanadhi River and the Manimuthar River in Tamil Nadu are significant perennial rivers flowing east from these hills.
The Ashambu Hills include the Indian Ecoregions of South Western Ghats moist deciduous forests above 500 metres (1,600 ft), South Western Ghats montane rain forests above 1,000 metres (3,300 ft) and shola-grasslands complex on peaks above 1,600 metres (5,200 ft).
These hills are noted as the habitat for at least 2,000 species of medicinal plants, of which at least 50 are rare and endangered species. There are also wild relatives of jackfruit, mango, cardamom, turmeric and banana.
Endangered mammals here include the Bengal tiger, Indian elephant, lion-tailed macaques, Nilgiri tahr and the vulnerable gaur, sloth bear, Malabar spiny dormouse and Nilgiri marten. There are also Jerdon's palm civet, gray slender loris, great pied hornbills and king cobras. Ecotourism is popular in the area.
The eastern side of the hills in Tamil Nadu includes the Kalakkad Mundanthurai Tiger Reserve (KMTR), a 895 square kilometres (346 sq mi) protected area. The Kerala side of the hills hosts the 128 square kilometres (49 sq mi) Neyyar Wildlife Sanctuary, the 53 square kilometres (20 sq mi) Peppara Wildlife Sanctuary, the 171 square kilometres (66 sq mi) Shenduruny Wildlife Sanctuary and the Kulathupuzha and Palode Reserve forests near Courtallam. The Naraikadu forest or “grey jungle”, surrounded by the Kalakad Mundanthurai Tiger Reserve, is privately owned by the Dhonavur Fellowship. This community has restored and protected the area so well that it is one of the best preserved forest tracts in the whole Ashambu Hills.
These protected areas in the Agasthyamala Hills comprise the Agasthyamalai Biosphere Reserve (ABR). This reserve includes 3,500.36 km2 (1,351.50 sq mi) out of which 1,828 square kilometres (706 sq mi) is in Kerala and 1,672.36 square kilometres (645.70 sq mi) is in Tamil Nadu.
The Western Ghats, Agasthyamalai Sub-Cluster, including all of Agasthyamalai Biosphere Reserve, is under consideration by the UNESCO World Heritage Committee for selection as a World Heritage Site.
There are several Hindu Temples and seasonal waterfalls which are important tourist attractions in these hills. At Suruli Falls there is a 2-stage Cascading water fall The Suruli River supplying the falls originates from the Meghamalai Hills. The falls drop from a height of 150 feet (46 m) collect into a pool, flow for a short distance and again plummet an additional 40 feet (12 m). Near the falls are 18 caves some of which represent Indian rock-cut architecture temples of the 18th Century. This popular destination for tourists and devout pilgrims is easily reached by road 56 km (35 mi) from Theni and 10 km (6.2 mi) from Cumbum in the Theni District.
Many pilgrims climb Agasthyamalai in the core of the hills to perform a puja ceremony at the Agasthya Murti on the top the Peak. Most pilgrims use the well-worn path through Peppara Wildlife Sanctuary on the Kerala side. The trekkers start from Bonaccord estate in Thiruvananthapuram district with a guide from the Forest Department. The first night is spent at a camp facility set up by the Department in the middle of the forests. Trekkers reach the peak the next day and return to the camp the same day. Only 100 pilgrims per day are allowed on this route during the January February season.
