Anjneri Hill
Anjaneri is an attraction of Nasik city, which is also an important fort in the Trimbakeshwar region. Situated at 4,264 feet (1,300 m) above sea level, it lies between Nasik and Trimbakeshwar.
Anjaneri is the birthplace of Hanuman, and is named after Hanuman's mother, Anjani. It is said that God Hanuman spent his childhood in these mountains. Being the birthplace of Lord Hanuman, Anjaneri has major significance for the devout and hikers alike. 108 Jain caves are found here dating back to the 12th century. The area around Anjaneri was once ruled for a brief period by Veersen Ahir (also spelled Abhir), who made it his capital.
Along with the cave, believed to be the place where Lord Hanuman was born, there is a Anajani Mata temple. A lot of other places associated with the life of Lord Hanuman are also there, which can be seen while trekking on the hill. One such place is a cave, which is believed to be the spot where Lord Pawan Dev took Bal Hanuman when he was hit by the 'vajra' of Lord Indra. Also, there is a Mata Anjana temple; the place where Goddess Anjani meditated for a child, and Shiva ultimately appeared in front of her to bless a boon. There are two pindies inside the temple; the big one is of Mata Anjana and the small one is of Bal Hanuman. A cave decorated with inscriptions that are as old as 1000 years also appears while trekking on the hill.
