During the tour of Mount Abu, near each tourist location, I read display boards narrating the History of the Lake and Temples in Mount Abu. Thanks to Rajasthan Tourism. Though it was written in Hindi, I am trying my best to translate it into English as a summary:
It is believed this lake was dug by God with nails, thus the reason it is named Nakki Lake. Besides the Himalayas, it is the only natural lake situated at a height of 1200 meters above sea level in India. Each year, Vaisakh Purnima (Buddha Purnima), nearby Tribesmen visit Nakki Lake for the holy bath. Nearby is the Raghunath Ji temple.
- Gaumukh Vashistha-Ashram
As per scriptures, it is known that Lord Shree Ram and his brothers had Yog education at this Ashram of Arbudaanchal by Guru Vashistha. At Vashishtha ashram Saraswati river is flowing via Gaumukh.
- Arbuda Devi (Adhar Devi) Temple
Arbuda Devi temple is mentioned within the Skanda Mahapurana, written by Ved Vyaas. Goddess Arbuda is here as Katyayani, the sixth form of Navadurga. The temple is approx. 5,500 years old. The temple is one of the Shakti Peeths out of 52. Arbuda Devi is also known as Adhar Devi.
- Achalgarh
Achalaleshwar Mahadev temple, Jain temple, and Gopichand ki Gufa (cave) one should visit at Achalgarh. Achalaleshwar Mahadev temple is one of the oldest temples of Mount Abu. Lord Shiva‘s great toe is worshiped at this temple.
