Visitors can hike, camp, picnic, or fish in the park. A trailhead provides accesses to a number of hiking trails in the surrounding forest, and ride on a popular horse trail.
Collier Memorial State Park features the Collier Logging Museum, an outdoor museum with a large collection of historic logging equipment. Some items date back to the 1880s and many are quite rare. The collection includes ox drawn "high wheels" used to raise the forward end of logs off the ground so they could be skidded through the forest to a collection area.
Collier State Park is located in Southern Oregon, off US 97, 30 miles north of Klamath Falls, near the Oregon-California border.
