Though the smaller islands in the group are low-lying, the larger islands are very hilly, with many peaks of more than 150 metres (490 ft) and some more than 200 metres (660 ft).

The highest elevation in the Beaver Island Group is 234 metres (768 ft).

Beaver Settlement lies on the island, with an airstrip nearby.

Wildlife on the island includes gentoo penguins, South American gray foxes (introduced, not to be confused with the Falkland Islands wolf), peregrine falcons, crested and striated caracaras, guanacos, fur seals, and many seabirds.

The Beaver Island Group has been identified by BirdLife International as an Important Bird Area.
