Three Island Crossing State Park, Idaho, USA

Truck with large trailer at Three Island Crossing State Park

History and a great place to camp located east of Boise.

It was late in the day…and with two or three RV parks to choose from (one right on the freeway), we went a little bit off the beaten path. And drove an extra mile or so and landed at Three Island Crossing State Park. The park features expansive views, spaces galore, and wonderful shade trees. A bonus is a museum and historic Oregon Trail wagon tracks emerging from the Snake River.

Three Island State Park a great spot to stop your RV or trailer and it’s got a great history. Located on the Snake River at Glenns Ferry, Three Island Crossing was familiar to Oregon Trail pioneers. It was one of the most famous river crossings on the historic trail. Pioneer travelers used the three-island crossing until 1869, when Gus Glenn constructed a ferry about two miles upstream. You can learn all about this important spot by visiting the Oregon Trail History and Education Center just steps from your RV. The second Saturday each August, the Glenns Ferry community sponsors a crossing commemoration that features local Native Americans, area ranchers, and other community members. Events include living history presentations and historic skills fair.

This park features more than 100 tree-lined sites. Many offer electricity. They also have showers and a dump.

An added bonus: Just a couple of miles from the park, we found an elk farm with  frozen elk steaks to stock up our freezer (you can see the “Elk for sale” sign from the freeway). The steaks were some of the best we’ve ever eaten!
