He began climbing and trekking in the range around
Mumbai, the
Western Ghats. His first visit to the Himalayas was almost 40 years ago. His main contribution to Himalayan climbing has been to explore unknown areas and, in number of cases, to open up climbing possibilities. Among his major ascents are
Devtoli (),
Bandarpunch West (), () in 1995, and
Lungser Kangri (), the highest peak of
Rupshu in
Ladakh. He led eight international joint expeditions, Chong Kumdan Kangri I (), Sudarshan Parvat, Padmanabh (), and the
Panch Chuli and
Rangrik Rang groups. In 1974, he fell into a crevasse at , deep inside the formidable
Nanda Devi Sanctuary. He was carried by his companions for 13 days to the base camp where a
helicopter rescued him. He was operated on for a dislocated hip-joint and had to spend two years walking on crutches, but that did not keep him out for too long and he has climbed for three
decades after the injury. ==Publications==
