Guernsey State Park provides seven campgrounds. Five are around the lake. All campgrounds include comfort stations, picnic tables, fire grills and drinking water. We also have a trailer dump station located at the south entrance to Guernsey State Park. This park provides the finest examples of Civilian Conservation Corps (CCC) work in the Rocky Mountain area. Built by the CCC, the Guernsey Museum, the Castle and Brimmer Point are available to explore. The museum is perched on a high cliff, overlooking the water. The building itself is made of hand hewn timbers and hand forged iron. The roof is framed with the timbers and covered with split cedar shakes, and the floors were formed by pieces of smooth flagstone. The Castle, with its giant fireplace and winding steps, leads to an observation area for a spectacular view of the park.

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 ten 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. 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. The landmark still remains much the way it looked to pioneers on wagon trains journeying West.
