This is the largest island located in the
Great Salt Lake. The park covers over 28,000 acres, and is home to coyotes, antelope and mule deer, as well as the largest publicly owned herd of bison in the nation, currently numbering about 600 head. The bison are rounded up at the end of October by horse and helicopter, and corralled for four days to receive vaccinations and general health check-ups. Visitors can participate in the bison auction following the round-up, where bison sales help control herd numbers. Other activities include swimming, guided horseback rides and horse rentals, hiking, and camping. Historical sites on the island include the Fielding Garr ranch, built in 1848 of materials native to the island, and open to the public through October. Park facilities include modern bathrooms and showers, a visitor center, waste disposal, picnic area with group-use pavilion, boat ramp and marina. Park entrance is accessed via I15 to exit 335, Antelope Drive.
