Three Island Crossing was one of the most famous spots on the Oregon Trail. This is where emigrants had to decide whether to cross the Snake River or endure the longer, drier, more difficult trail on the south bank.



The park features full-service camping, teepee rentals and a new Oregon Trail Interpretive Center with exhibits and a gift shop. Each August there is a reenactment of the river crossing. Contact the state park office for dates and times.
