Guru Shikhar, a peak at an altitude of 5,676 feet (1722 meters), is the highest point in Rajasthan. It is located at a distance of 15 km from Mount Abu. It has a commanding view of Abu and its surroundings. This peak is the home to the temple of Dattatreya, an incarnation of Lord Vishnu and the peak is called Guru Shikhar after him as Guru Dattatreya had dignified this place and his footprints are sanctified here in a rock in a cave. Foot prints of swami Ramanath are also here who enshrined the statue in Raghnathji temple in Abu. Close to the shrine is a temple of Guru Dattatreya's mother which is too worth- seeing.
There is also a huge and giant bell suspended from a wooden frame with an inscription dated 1411 in the Dattatrya temple, its toll is heard upto a long distances from here. The cold sweeping breeze in adjunct with the panoramic view of the natural scenery full of charm and dense distant forests fill in the visitors a throbing thrill.
