Just as Kalsubai boasts to be the highest peak in the Sahyadris in Maharashtra, Salher has the distinction of being the highest fort in the Sahyadris. 

Baglan is the fertile region being fed by the rivers Mokshaganga and Akshaganga. This is one of the areas rich in agricultural productivity, forests and wealth and the villagers here are quite well to do. Still, there are tribes like the Kokan and Bhils living on these hills. The perimeter of the Salher fort is around 11 Kms encompassing an area of around 600 hectares. 

The Salher fort is famous and known as the main place where Parashuram did his penance. After winning the earth and giving it as donation, he made land for himself to live in, by pushing the sea back with his arrows, right from this place. An ancient and historically significant place like this is also famous for its battles during the reign of Chhatrapati Shivaji Maharaj
The fort of Salher was captured by Chhatrapati Shivaji Maharaj in 1671, during his campaign of the Baglan region. This news reached the Mogul emperor in Delhi. He got incensed with this news and said “I have sent lakhs of cavalry but they have come back shamefully, now whom do I send?” The emperor then decided “As long as Chhatrapati Shivaji Maharaj is alive, we are not leaving Delhi”. He then called Ikhlaas Khan and Bahlol Khan and sent them with a cavalry of 20,000 horses to attack Salher. Ikhlaas Khan then laid siege of Salher Fort. When this news reached the Maharaj, he sent message to his Commander in Chief Prataprao through his secret agents “Go to Salher with your troops and drive off Bahlol Khan”. He also sent a parallel letter to Moropant Peshwa to go from Varghati Konkan along with his troops and meet Prataprao near Salher. As planned, both Prataprao and Moropant rode to Salher from both sides and a fierce battle ensued. Writings .
