The Nehru Mountaineering Institute is India's premier autonomous institute, established in 1965, in memory of Pt. Jawaharlal Nehru, a mountain lover. A lot of professional alpine trekkers cross you and the chance to interact with them, learning about their rigorous training schedules, and their adeptness.
If you like challenging yourself in natural terrain, you can also enroll yourself in a training courses to summit Mount Everest! The environs of the institute, while challenging, have an elitist air, accompanied naturally with the sense of conquering the seemingly impossible task of mountaineering. The experience of just visiting the institute is exhilarating, and if not compelling you to scale Everest, then atleast trek to one of the shorter routes in town!
