Guernsey State Park is a public recreation area surrounding the Guernsey Reservoir, an impoundment of the North Platte River, near the town of Guernsey in Platte County, Wyoming. The state park features multiple campgrounds, boat ramps, and hiking trails as well as exceptional examples of structures created by the Civilian Conservation Corps in the 1930s. Facilities are managed for the Bureau of Reclamation by the Wyoming Division of State Parks and Historic Sites.
The park had its beginnings with construction of the Guernsey Dam, which was completed in 1927. Beginning in 1934, workers with the Civilian Conservation Corps created recreational facilities on the land surrounding the dam's reservoir. Their labors came to an end in 1939. Park management fell to the state of Wyoming in 1957.
Lake Guernsey State Park (also known as Guernsey State Park Historic District, Lake Guernsey Park, Guernsey Lake Park, or Guernsey State Park) was declared a National Historic Landmark in 1997 for its Civilian Conservation Corps buildings and structures. The historic district contains 60 contributing resources: 14 buildings, 3 sites, and 43 structures, as well as 46 non-contributing resources.
The Guernsey State Park Museum offer information about the CCC and the natural and cultural history of the area. The park contains a separate National Historic Landmark, the Oregon Trail Ruts. Register Cliff, another feature of the Oregon Trail listed on the National Register of Historic Places, is located two miles southeast of the park.

  • Guernsey State Park is in a very scenic area in Southeast Wyoming. We drove around to see the sights and were not disappointed. We drove to the top of a mountain (the road was a little rough) and wow....  more »
  • We drove through this state park to see the historical sites. There is a daily fee per vehicle. We visited the castle, Brimmers Point, the dam and the CCC museum. All were well worth the drive...  more »
  • Fabulous! My family and I floated from just below the dam to Register Cliff today. Friendly staff at the gate. Clean restrooms. We'll maintained parking.
  • This park is a gem. Very few people even on Memorial Day weekend. The views are amazing, as is the history. This park was mostly built by the CCC, darn near a hundred years ago. The museum details all of this as well as life in this area. I have had the pleasure of exploring every foot trail in this park and all of them are great. Make a loop out of 2 or 3 of trails for a great hike. The amount of work that went into these trails is stunning. Rock features everywhere, man made and natural. After a hike, cool off at the Castle(made of massive stones that stay cool almost all day) to enjoy more great views and one of the coolest man made structures in the west.
