Ali Sher Khan probably built the fort on the east end of this rock in the 17th century, but the Dogras trashed and rebuilt it. It's a half-hour climb to the partly reconstructed fort, from where there are fine valley views. The path starts beside the Hilton International Hotel. From the polo ground, there is a track around the base of the rock. Knock and yell for assistance if the fort door is closed.
You can get to the summit (and the ruins of more fortifications, and amazing views) by a steep, dry, three-hour scramble up the west end of the rock from near the Hotel Sadpara International. Take care, as this route has some false paths taking you near unprotected and dangerous drops.
