The landscape features a mix of evergreen, semi-evergreen, and moist deciduous forest types. Visitors can access a deer rehabilitation center located within the perimeter. The terrain is part of the Western Ghats, a UNESCO World Heritage site known for high biodiversity. The site offers a suspended bridge, boating facilities on the reservoir, and trekking trails.
