Three Island Crossing State Park is a great place to learn about the Oregon Trail or begin exploring the Owyhee Canyonlands!

Three Island Crossing State Park is located on the Snake River at a historic crossing point for the original travelers of the Oregon Trail. Home to the Oregon Trail History and Education Center, Three Island State Park is a great place to learn about the pioneers and early settlers to the area.

The park has several campsites with amenities available, as well as cabins that you can rent. Located in the Owyhee Canyonlands, Three Island Crossing is an ideal place to stay while you explore Glenns Ferry and the surrounding countryside by foot, bike or even horse!

From I-84, take exit 121 for Glenns Ferry. Turn left onto 1st Ave, left on Commercial Ave, and then right on Madison Ave. Travel about 1 mile to the park entrance.
