Chobhar Gorge is the place where, in prehistoric times, Manjushri cut a gash in the mountainside, creating a gorge that would drain the Kathmandu Valley of its lake. Here, one can hire a guide and visit the underground caves and tunnel system. One of the caves contains a small lake, and it was in these caves that Ra Lotsawa and Guru Goraknath once meditated. | ExPlore with Phub TsheRing.
