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.

This park is 30 miles around. There are many back roads and switchbacks to drive up, around and over the mountains and hills. There is a spectacular view of the lake no matter where you are.

Sandy Beach Campground at Guernsey State Park was a great retreat after a day on the road. We'd visited nearby historic Fort Laramie and cooked dinner on the grill while listening to waves lap on the shore. There were some herons in the area to amuse us.

From the yurts to the CCC structures, this park is so much more than a simple water park! Did some canoeing - it was great, but I was so impressed by the Civilian Conservation Corps structures. They are amazing - complete with their original displays! YURTS RECOMMENDED!!!

This canyon and reservoir are so beautiful. Park employees are very helpful. Love the drive around the reservoir and would love to stay in a yurt! Make sure to check out the "castle" - a cute picnic area built by the Conservation ire in the 1930's. Love the small museum about the area and the Conservation Core pictures are amazing.... More

We have visited Guernsey State Park on three consecutive weekends already this summer. The campgrounds, parking areas, restroooms, everything - - so clean and very well maintained. The lake is high this time of year and seems to go on almost forever. Definitely an oasis in the not-quite-as-pretty part of Wyoming.

I apologize, I can't reasonably blame the Wyoming state park system for the neighbors we had when we camped here, but it was a very restless night. The reservoir is nice, the nature is nice where you can find it, but the facilities are minimal. Overall, it was satisfactory for Our mini family reunion with a very good fire pit... More

After reading good reviews of the campground, I gave camping here a shot. Big mistake. If you like the constant sound of trains, the 24x7 lighting of a train switching yard, and proximity to a light infantry military training base with active helicopter flights and armament explosions, then you'll like camping here. Otherwise, stay the heck away. Trains were running... More

I was looking forward to visiting this park only to find out that the lake had been drained, for irrigation purposes down stream.
