Named after the trident of Lord Shiva, Trishul is the group of three imposing peaks of western Kumaon near the Bageshwar district. The main peak, Trishul I, is notable for being the first peak over 7,122 metres to have ever been climbed way back in 1907. Trishul II and Trishul III were first climbed in 1960 by a Yugoslav team from the Bidalgwar Glacier, scaling the supreme heights of Trishul II from the southern ridge and Trishul III from the northern ridge.
Before ski tourism gained popularity as a winter sport in Auli, Trishul was amongst the few peaks that were used as training spots for ski-equipped patrolling officers of the Indo-Tibetan Border Police Force. It is reported that an expedition to scale the peak in 1958 took the mountaineers four whole days to climb and a mere 90 minutes to ski down to their base camp. The gorgeous Roopkund Lake rests at the bottom of these slopes, which is also known as the Mystery Lake since around 600-odd skeletal remains of horses and humans were once found here. The best views of Trishul are to be seen from Kausani and Bedini Bugyal.
