The range runs from southwest to northeast, parallel to the main ranges of the Southern Alps / Kā Tiritiri o te Moana.

At the northeastern end, the range terminates at Jagged Peak (2,706 metres (8,878 ft)), whence a ridge connects to the Jollie Range.

The highest point on the range is Mount Arrowsmith (2,781 metres (9,124 ft)).

[1] It is believed that the range was named in honour of John Arrowsmith, the 19th century British cartographer.
