Korigad - DOT-Maharashtra Tourism
To the west of the Mulshi dam is the Mawal of Korbarase. The forts Korigad and Ghangad lay this region. Korigad is built near the Savashni Ghat, which connects Lonavla and Pali. This fort is well known due to its fortification that is still intact. To visit the forts in this region, one needs at least 3-4 days leisure. One can also go for a cross-country trek which includes Korigad, Ghangad, Tailbaila Walls, Sudhagad and Sarasgad.
Chhatrapati Shivaji Maharaj incorporated this fort in Swarajya along with Lohgad, Visapur, Tung and Tikona in 1657. On March 11, 1818, Col. Prother invaded this fort but could not succeed even after prolonged fighting. Finally he succeeded on 14th March, by dropping a cannon ball where the ammunition was stored. Along with this fort the English also conquered Ghangad.
