The main north-south ridge of Kusum Kanguru forms the border between the Dudh Khosi to the west and the Hinku Valley to the east.

Kusum Kanguru is one of the first high snowy mountains that become visible while trekking from Jiri to the Mount Everest base camp.

With an altitude of 6,367 metres (6,369m or 6,370m according to other map sources),[3] the mountain is classified as a trekking peak, but it is considered one of the most difficult to climb.

[3] The first successful ascent of the main summit was made by Bill Denz of New Zealand on 7 October 1981, climbing the southwest buttress (west face), and descending the northwest flank.

1988 British Expedition led by Nick Mason, John Diplock and Julian Holmes conquered the previously unclimbed East Face.
