Sirumalai (Tamil: சிறுமலை) is a region of 60,000 acres (200 sq km) situated 25 km (16 mi) from Dindigul and 40 km (25 mi) from Madurai,Tamil Nadu, India. There are many high hills in the area. Hillock International School is located in Sirumalai. Sirumalai is a dense forest region with a moderate climate throughout the year. The altitude of the hill is 1600 metres above sea level, and it contains diversified flora and fauna and a variety of animals.
The Hill has totally 18 hair-pin bends and on the 18th bend you can able to find a church and a view point from where you can watch the beauty of Dindigul city and also the "Dindigul Rock Fort". The hill contains a small waterfall as well. The famous Sirumalai banana is slowly disappearing due to a number of diseases associated with it, which no one has been able to solve. Sirumalai farmers, in order to get maximum business, have planted silver oak excessively to an extent that in many parts it has become monoculture.
Man made fires on the Hills have destroyed medicinal plants and threaten the fauna habitat. Fires are often set to promote vegetation growth used for animal fodder, clear land for cultivation or improve access to timber. It is said during the era of Ramayana when Lord Hanuman carried the Sanjeevi hill a fragment which fell down became this hill.
Mathamalai Annai Veilankanni Church is situated on top of one of the hills. It can be reached by bus from the Dindigul bus stand (need to walk for 2 km approx. from the bus stop to the slopes of the Mathamalai hill).
