Although winter is still upon us, the park is beautiful this time of year. You can drive through, take a hike, or stop for a warm lunch at one of the shelters. The yurts are available year-round and the wood stoves are perfect for keeping you warm at night, or heating up a pot of soup. Outside grills can be fired up for larger meals.

To reserve a yurt during the off season, please call 307-836-2334. If you aren’t able to speak to someone, leave a message and your call will be returned. Remember to bring plenty of warm clothes, boots, hats and gloves as well as a camera. Camping in the winter is a unique experience that you should try.

Announcement - Guernsey Reservoir Silt Run, Updated

Important Information: Updated: 9/19/2016

Reclamation Announces Annual Drawdown of Guernsey Reservoir

News Release from U.S. Department of the Interior
Bureau of Reclamation

MILLS, Wyo. - The Bureau of Reclamation will be lowering the water level in Guernsey Reservoir-as the 2016 irrigation season draws to a close.

Guernsey Reservoir levels are expected to remain accessible for boating recreation through September 18. Reclamation will begin drawing down Guernsey Reservoir on the evening of Sunday, September 18, and the boat ramps will quickly become unusable. Reclamation advises that watercraft be removed from the reservoir by the evening of Sunday, September 18.

Guernsey Reservoir releases are expected to gradually decrease beginning on September 14 with the end of major irrigation demands. On the afternoon of September 16, releases from Guernsey Reservoir will be set to approximately 2,000 cfs until the end of September when they will be discontinued for the winter.

Glendo Reservoir levels are expected to continue gradually declining and reach a water surface elevation near 4589.5 feet (approximately 140,000 acre-feet) around September 19. Glendo releases will be discontinued for the winter by September 25 and Glendo Reservoir levels will then stabilize and slowly increase after October 1. Boaters, recreationists, and irrigators should take proper precautions regarding changing river flows between Glendo and Guernsey Reservoirs and the lowering of Guernsey Reservoir.

About Guernsey State Park

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.
