Trails
An extensive network of trails was originally planned and partially built during the operation of the CCC camps. Ever since that time hiking and trail use has been a major feature at Guernsey State Park. Approximately 14 miles of CCC trails have been restored on the park. Starting point for the trail system is at the Brimmer Point turnoff. The trail system consists of several loops which provide a variety of scenic views of the park, reservoir and the dam. Most of the trails are moderately physically demanding. The Oregon Trail was one of the primary routes used by the immigrants' westward migration across the plains from 1841 to 1869. Today, in many parts of Wyoming, remnants of The Oregon Trail can still be seen.

Directions from the park
We also have a trailer dump station located at the south entrance to Guernsey State Park. Some of the best examples are the "ruts"; located just 1/2 mile south of the town of Guernsey, off Highway 26. Register Cliff located two miles southeast of Guernsey provided travelers with a "chalkboard" where they placed their names for those who followed.
