Perched at 1,722 meters (5,650 ft), Guru Shikhar is the literal high point of Rajasthan—and of the entire Aravalli Range—offering a horizon-to-horizon sweep over forested ridges, granite domes, and the lake-dotted hill town of Mount Abu below. It’s a rare mix of sacred pilgrimage, easy-access hiking, and serious science, thanks to the venerable cave-temple of Lord Dattatreya at the summit and the Mount Abu Observatory nearby.
