Three Island Crossing

Three Island Crossing State Park sits along the Snake River with natural islands that helped pioneers cross the waterway during westward migration. The park includes camping areas, a visitor center, and trails that follow the historical route.

The river crossing served as a vital passage on the Oregon Trail until 1869 when a ferry service opened two miles upstream. This development eliminated the need for the hazardous water crossing.

The Oregon Trail History and Education Center displays how pioneers and Native Americans lived while showing the hardships they faced during westward expansion. The exhibits help visitors understand the daily struggles both groups experienced.

Visitors can reserve camping sites in two areas: the Trailside Lower Campground and Wagon Wheel Upper Campground, both with water and electrical hookups. It's helpful to check available amenities in advance and plan according to the season.

The park holds an annual commemoration every second Saturday in August with living history demonstrations and traditional skills presentations. Visitors can observe authentic techniques and daily life from the pioneer era during these events.
