Three Island Crossing State Park

Three Island Crossing State Park is a state park of Idaho, United States, interpreting the site of a ford of the Snake River on the Oregon Trail. The park is located in Glenns Ferry in Elmore County. The site was used as a crossing until 1869 when Gus Glenn built a ferry across the river about 2 miles (3.2 km) upstream. There is a campground with serviced campsites and cabins along with a free interpretive visitor's center at the park.
