Physiographically, this area forms the Kalimpong Range, with the average elevation varying from 300 to 3,000 metres (980 to 9,840 ft).

While Kalimpong is the only municipality, Dungra is the sole census town in the entire area.

[4][5] While the first degree college in the subdivision was established at Kalimpong in 1962[6] the entire subdivision (and now the entire district), other than the head-quarters, had to wait till as late as 2015 (more than half a century) to have their first degree colleges at Pedong and Gorubathan.

Mongpong is located on the fringe of Mahananda Wildlife Sanctuary and is home to several birds like brahminy duck, pintail duck, poachard, mallard and bar-headed goose that come here from Central Asia and Ladakh during winter.

Moreover, this is an ideal destination for adventure seekers as it offers trekking, hiking, and bird watching.
