[3] The Ponmudi Dam (294 metre length) was constructed in 1963 across the Panniar river, nearly 15 km southeast of Adimali, on the way to Rajakkad.Thopramkudy is the nearest town.

It gained its importance when the Government of Kerala allowed mass settlements of people from the neighboring districts in the Mid 20th Century.

Since it intersects two major roads and is a popular resting point on the way to Munnar, Adimaly slowly grew in size.

Adimaly for decades served as a commercial hub for many smaller towns nearby such as Kunjithanny, Anachal, Rajakkad, Shanthanpara, Vellathooval, Murikkassery, Thopramkudi, Panikkankudi, Kallarkutti etc.

However, the reliance on Adimaly by these smaller towns faded during the years due to development of adequate roads and other infrastructure, few have emerged as self-reliant commercial townships.

The rapids of Cheeyappara descend from a height of about 1000 feet, churning with force onto 13 rock slabs in the vicinity of a bridge on National Highway 49.

One of the tributaries of The Periyar River cascades steeply from the top of a hill to a depth of about 200 feet, into a gorge.

[citation needed] Adimaly generally has a cool climate throughout the year, typical of the higher altitudes, though not as cold as Munnar.

Rains in Adimaly sometimes continue for hours or even days without any dry spell, which may bring the town to a standstill.
