Trishul Mountains are a set of three Himalayan mountain peaks of western Kumaun that are grouped together. The Trisul Mountains form the southeast corner of the ring of peaks encircling the Nanda Devi Sanctuary. Trisul is named after the trident of the Hindu god Shiva. These lofty Trishul Mountains can be best seen from Kausani and Bedini Bugyal.

Location of Trishul Mountains
Trishul Mountains are located in western Kumaun which is in the Uttarakhand state of India near the district of Bageshwar. They are situated fifteen kilometres west-southwest of the majestic Nanda Devi.

Features of Trishul Mountains
The three peaks are called Trishul I, Trisul II and Trisul III. The main peak is Trishul I which is situated at a height of 7,120 metres (23,359 feet) above mean sea level. Trisul I is the first peak over 7,000 m to have ever been climbed, in 1907. Trisul II and Trisul III are situated at a height of 6,690 metres (21,949 feet) and 6,007 feet (19,708 feet) above mean sea level respectively. This massif is a north south ridge with the Trishul I situated at the north end and Trishul III at the south. The geographic coordinates of Trisul I are 30 Degree 18`46 north, 79 Degree 46`38 east. The mountain prominence (it is a measure of vertical separation between mountains) of Trishul is 1,616 metres (5,302 feet) above mean sea level.

Trishul I was first climbed in the year 1907. The first climbing exploration of Trisul I was made by explorer and mountaineer T. G. Longstaff in the year 1905. He emphasised on the western and southern sides for scouting. Longstaff returned in 1907 with his team and climbed through the Rishiganga valley, to the north of the mountain, onto the Trisul Glacier, which lies on the east side. From there they ascended the northeast flank to the north ridge, reaching the peak. The climb of Trishul I marks the first use of supplementary oxygen in a major climb.

Trisul II and Trisul III were first scaled in 1960 by the Yugoslavian team. The team climbed from the Bidalgwar glacier and achieved the summit of Trisul II via the southern ridge and Trisul III via the north ridge.
