Nedumkayam Rainforest is located approximately 15 km from Nilambur in Malappuram district of Kerala. 'Kayam' in Malayalam translates to deep part of a river. The Nedumkayam rainforest can be reached via Karulayi, a small town situated on the banks of the Karimpuzha River. The entire area is surrounded by tall, trees that block sunlight giving the impression of night all the time. For adventure enthusiasts, Nedumkayam offers excellent trekking opportunities, the most popular one being the 3-hour trek to nearby Mundakadav waterfalls.

Access to Nedumkayam requires prior permission from the Indian Forest Service due to conservation efforts aimed at saving the existing forest land.

Historical and Cultural Significance
Nedumkayam has the world's oldest teak plantation, established during the British colonial era in the 1840s, in a vast area of 2.3 hectares. You can see a wooden house built during the British rule here.  

Nedumkayam is home to the Cholanaikkars, an ancient tribe residing in the Mancheeri area. They spend lives in the open or under rock shelters.

Biodiversity
The rainforest is part of the Nilgiri Biosphere Reserve. The fresh air and clear water that flows through, along with rare species of flora and fauna makes the place a popular destination for tourists.

Visitors often see elephants on the journey through the teak plantations. There is an elephant taming centre at Nedumkayam.  Many mammals of the western ghats such as bisons, tigers, macaques, deer, and wild cats can be seen here. The area also has more than 200 species of birds.
