A historic fortress located at Aamby Valley in Lonavla. This trek is the easier than any other treks. The steps going to the fort is hectic. The duration is 1 hour. The entrance gate and the ramparts are still intact. There is a temple dedicated to Goddess Koraidevi and there is a large Maratha era cannon in front of it. The best time to visit is during the monsoon season. It is an ideal place for trekkers.
