There are two forts that constitute Rajmachi fortification, Shrivardhan Fort is one of them, the other is the Manaranjan Fort. Apart from a huge defensive wall that was built to strengthen the place against attack, there is no further construction there. But the uphill view is completely breathtaking and awe inspiring. It is located 9 km from Lonavala at Rajmachi Village in the Sahyadris mountain range, at a height of 900 m above sea level, thus might have used as the watch point for that region. The place is home for many different species of birds because of immense greenery here, and an attractive spot of visit for the tourists and trekkers. The beauty of this place is unmatchable during monsoon when it gets entirely blurry with fog.
There are couple of forts nearby that can be added to your visit to Shrivardhan Fort like Lohagad Fort and Visapur Fort. Other than them Bedsa caves, Duke's Nose, Tiger's Leap and Kune Waterfalls can also be visited.
To reach Lonavla lying on the Mumbai-Pune Expressway, one can travel by train or bus, from nearby towns like Khopoli, Karjat, Talegaon Dabhade, etc. While with major towns like Mumbai (82 km) and Pune (65 km) also, Lonavala is well-connected. Shrivardhan Fort is just 13.5 km away from the town. There are cabs and autos available to get here.
Monsoon is considered to be the best time to visit Shrivardhan Fort, between the months from June to Sept.
