Mahuli Fort at 2815 ft, is a popular trekking destination and a paradise for rock climbers because of many nearby pinnacles with interesting names like Vazir, Vishnu, etc., given by the local trekking and climbing fraternity. This mountain complex is actually a group of two or more hills with common cols and pinnacles.
It is the highest point in the Thane district. The forest surrounding Mahuli has been declared as a sanctuary. Shahaji, father of Shivaji, occupied this fortress. The fort has been declared as a protected monument.
Besides an open Shiva temple, there is a small perennial drinking water cistern on top. There are also three caves, of which the larger can be used as overnight shelter, like on many other such natural hill forts in the Maharashtrian Western Ghats (Sahyadri Range). There is a stone arch historically known as the ‘Kalyan Darwaja’, but the dome of the arch is now broken.
