Nanmangalam Reserve Forest Trail

Nanmangalam Reserve Forest is a patch of tropical dry evergreen scrub forest on the southern edge of Chennai, Tamil Nadu, India, in the Nanmangalam and Medavakkam area. It is one of the few sizeable green spaces left in the south of the city and is managed by the Tamil Nadu Forest Department. Access is by road: visitors usually take an app cab or auto from Velachery MRTS or Metro station, a journey of roughly 30 to 40 minutes depending on traffic, or use local MTC buses towards Medavakkam and Nanmangalam. Parking is informal near the forest edge, and because trail access and entry rules can change, it is wise to confirm current conditions with the Forest Department before travelling. The walk covers about 3 to 6 km of forest paths, depending on the route chosen, and takes 1.5 to 2.5 hours. The terrain is flat to gently undulating, at roughly 20 to 40 m above sea level, so elevation gain is negligible and difficulty is low. Surfaces are packed earth and laterite with occasional loose stones and tree roots. Shade comes from scrub canopy and is intermittent, with open stretches that heat up quickly after sunrise. The forest supports birds, butterflies, reptiles and small mammals, and early walkers often hear peafowl and see drongos, bee-eaters and other scrub species. Trails are not heavily signed, so landmarks are mostly clearings and junctions between paths; an offline map is helpful for keeping orientation, and turning back at any junction is straightforward since the area is compact. No water sources, huts or formal shelters are provided inside, so visitors carry all the water they need. Walking in a small group is advisable, and litter should be carried out.
