Sirumalai
Sirumalai () is a region of situated from Dindigul, from Madurai, and 125 km from Trichy, Tamil Nadu, India. There are many high hills in the area. Sirumalai range is the last mountain range of the Eastern Ghats. The last mountains of the Sirumalai mountain range are the Azhagar Kovil Hills which are present in Madurai District. Azhagar Kovil Hills are the most important place of worship for the Hindu religion. Tracking is allowed in the Azhagar Kovil Hills. The nearest Eastern Ghats hills to Sirumalai Hills are the Narthamalai Hills. Sirumalai is a dense forest region with a moderate  climate throughout the year. With an altitude of 1600 metres above sea level, it contains diversified flora and fauna. The hill has 18 hairpin bends. On the 18th bend are a church and a viewpoint of Dindigul city and the Dindigul Rock Fort. The hill contains a small waterfall as well. The famous Sirumalai banana is slowly disappearing from disease, which scientists have been unable to prevent. Man-made fires on the hills have destroyed medicinal plants and threatened the fauna habitat. Fires are often set to promote vegetation growth used for animal fodder, clear land for cultivation, or improve  access to timber. Attractions.

In the region of Sirumalai, the Agasthiarpuram is a holy place where siddhas (monks) have lived since ancient times. The area is surrounded with medicinal herbs and plants.

Other rare plants such as lianas and orchids also occur in the higher elevation evergreen tracts. Coffee estates form a major portion of the present-day landscape. These reserve forests are protected under the Tamil Nadu Forest Department. A rich animal life including threatened animals such as the slender loris, gaur, sambar deer, sloth bear, Asian palm civet, Indian hare, jungle  cat and Indian pangolin are to be seen in the wild. Birds such as Indian peafowl, Asian koel, Indian grey hornbill and even the endemic blue-winged parakeet are found in these forests. Threatened reptiles such as the python molurus, Indian star tortoise, and venomous snakes such as Indian cobra, Russell's viper, common krait and the endemic bamboo pit viper and the little-known striped coral snake are found here. Lizards such as the Bengal monitor, the Indian chameleon, the flying lizard, common green forest lizard, lesser snake-eyed lacerta and Cnemaspis geckoes are to be seen here. Special  mention must be made of the only endemic reptile of the hill – the Sirumalai shieldtail snake Uropeltis dindigalensis, that is reportedly not found anywhere else.

A myriad forms of lesser-known insects and moths, etc. are present. Agathya Puram. Located in Sirumalai is Agathya Puram, named after the prominent Agathya Siddhar. Located in Agathya Puram is Silver Hill; this is the tallest hill in Sirumalai. It is said that the peak of the hill was made  up of silver but to avoid man's destructive actions during the Kali Yuga, the hill was transformed via alchemy into stone by Agathya Siddhar, hence the name "silver hill". The hill's silver glitter can be still seen in the sunlight. In the peak of this silver hill is a 500-year-old Shiva Lingam; the walk to top of the hill is about 30–45 minutes. The view from the silver hill is breathtaking. Agatthiyar SivaSakthi Sitthar Peedam. Agatthiyar SivaSakthi Sitthar Peedam is an ashram located at the silver hill in Agathya Puram. Food is served daily (Annadanam) and  lodging is available at the ashram. The ashram aims to promote various voluntary campaigns such as cleaning of the hills.
