The preserve lies on the northern side of the Seward Peninsula, with 2,697,391 acres (1,091,595 ha).
The preserve extends along the coast from a point to the west of Deering along Goodhope Bay to Cape Espenberg, then westward along the shore of the Chukchi Sea.
The boundary moves inland to avoid the village of Shishmaref and the Shishmaref Inlet, then rejoins the coast to include Ikpek Lagoon.
A narrow corridor connects the Ikpek Lagoon section to the main preserve.
The interior portions extend to and across the Continental Divide as far as the Bendeleben Mountains.
The region around the continental divide includes volcanic areas such as Serpentine Hot Springs and lava fields between the Noxapaga River and the Kuzitrin River.
The preserve's high point is Mount Boyan on the south border.

There are no roads into the preserve.
Access to the preserve is by bush planes or boats during summer months and by ski planes, snowmobiles or dog sleds during the winter.
Bering Land Bridge National Preserve contains several sites of geological and prehistorical significance.
Serpentine Hot Springs is the preserve's most visited location.
Other notable locations in the preserve include the Trail Creek Caves, Devil Mountain Lakes, and the Lost Jim Lava Flow.
