Mahuli

Location
Its the highest point in the Thane district. The forest surrounding Mahuli has been declared as a sanctuary. Once Shahaji Raje, father of Chatrapati Shivaji Maharaj, had this fortress under his belt.
The nearest railway station to Mahuli is Asangaon. One can catch either Asangaon or Kasara Local from Mumbai CST, which could also be caught at Kalyan. Junction. 4 Km. walk from Asangaon station will take you to the base temple in 11/2 hours. 3 hours trek will take you to the summit.
Precaution
Its better to take sufficient amount of water stock from temple itself since there isn't water source in the way. Its better to have someone with you who had already been here because the area at the top is very confusing. Make an inquiry in the temple whether the informative booklet of Mahuli(with the map) published by Nisarga Giribhraman Sanstha, is available. After reaching the top search for the caves only on the right side. Avoid going in months of March, April and May (water scarcity).
Sight Seeing
Mahuli can be undertaken as an one day trek , though overnight stay in caves/dens could be quiet enjoyable. One can view Kalyan Darwaja as well as old Temple.
