Sondai is not popular fort. Sondai is 9 km from Karjat. It offers a beautiful view of Morbe Dam, Prabalgad, Irshalgad, Rajmachi, Songiri forts, and Matheran mountain range. Sondai was used as a watchtower. Sondewadi and Wavarle are the base villages of Sondai fort. Sondewadi village is situated at 1/4th height of this fort.
There are 2 water cisterns on and steps are carved out of rocks to go on the topmost point where an idol of Sondai Devi stands. Two more water cisterns are on the way and have potable water. Waverle is another village from where a bit difficult approach to the fort passes through the dense forest.
