About Idamalayar Dam

Idamalayar Dam lies in the eastern highland zone of Ernakulam district, Kerala, in Kothamangalam taluk. Government information identifies Idamalayar Dam as a key water source connected with the wider Idamalayar irrigation system, while the reservoir forms a striking landscape within the forested Western Ghats. The site is better understood as major infrastructure in a sensitive natural setting than as an unrestricted recreation facility.

Travellers are drawn to the long approach through green country, reservoir views and the sense of remoteness beyond the more frequently visited Bhoothathankettu area. Wildlife, steep terrain, changing weather and operational restrictions all make it important to follow local instructions and avoid entering closed or forest-controlled areas. Anyone planning a dedicated visit should confirm current permission and access conditions first.

For responsible travellers, the wider Idamalayar landscape offers a strong impression of Ernakulam’s eastern forests and river systems.
