Trisul is a group of three Himalayan mountain peaks of western Kumaun, with the highest (Trisul I) reaching 7120m. The three peaks resemble a trident - in Hindi/ Sanskrit, Trishula, trident, is the weapon of Shiva. The Trishul group forms the southwest corner of the ring of peaks enclosing the Nanda Devi Sanctuary, about west-southwest of Nanda Devi itself. The main peak, Trisul I, was the first peak over to have ever been climbed, in 1907.

Sixty miles due north of you, as the crow flies, is Trisul, and to the east and to the west of this imposing 23,406-foot peak the snow mountains stretch in an unbroken line for many hundreds of miles.
Where the snows fade out of sight to the west of Trisul are first the Gangotri group, then the glaciers and mountains above the sacred shrines of Kedarnath and Badrinath, and then Kamet made famous by Smythe.
