Guernsey State Park - General Information

 

Guernsey State Park provides 19 campgrounds and 250 campsites. All campgrounds include comfort stations, picnic tables, and fire grills. 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 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. 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.

Wyoming Arts Council Invites Public to Plein Air in the Parks at Guernsey State Park

GUERNSEY, Wyo. – June 24, 2026 – The Wyoming Arts Council and Wyoming State Parks invite artists and community members to participate in and attend Plein Air in the Parks at Guernsey State Park, June 24–28, 2026. The public is encouraged to attend the event's concluding show and sale on Sunday, June 28.

Plein Air in the Parks brings together artists from Wyoming and the surrounding region to paint outdoors on location while celebrating the state's diverse landscapes and natural beauty. Since its launch in 2018, the program has grown into a popular annual event that encourages artistic exploration and connection with Wyoming's public lands.

Artists of all ages and skill levels are welcome to participate and may attend for one day or all five days of the event. Registration remains open through Eventbrite, and artists can continue to sign up to participate through Saturday. Throughout the week, participants will create original works inspired by the scenery, history, and character of Guernsey State Park.

The event concludes with a public show and sale at the Guernsey State Park Museum on Sunday, June 28, from 3 to 5 p.m. The reception offers visitors an opportunity to meet participating artists, view artwork created during the event, and purchase original pieces. Juried awards and the People's Choice Award will be announced at 4 p.m. State park day use fees will still apply Wednesday-Saturday for non-event participants, but will be waived for the Show and Sale. 

Plein Air in the Parks rotates among Wyoming State Parks each year, offering artists and visitors new opportunities to experience Wyoming's landscapes through art.

Registration is available at https://plein-air-in-the-parks-guernsey.eventbrite.com.
