Antelope Island State Park
A causeway reaches the Great Salt Lake’s largest island, where bison, shorebirds, beaches, ranch history, and mountain trails share a saline landscape.
Artwork inspired by Alfred Lambourne
Antelope Island is both a mountain island and one of the most accessible ways to understand Great Salt Lake. Changing water levels expose broad playas, concentrate birds and brine life, and alter the shoreline dramatically. Bison introduced in the 1890s now occupy open slopes alongside pronghorn and mule deer.
Drive slowly and treat bison as unpredictable wildlife, never as roadside livestock. The causeway and Fielding Garr Ranch add ecological and human context, while higher trails reveal how the lake’s apparent emptiness depends on wetlands, islands, and distant ranges.
