About

Guernsey State Park is situated along the shores of Guernsey Reservoir, within the North Platte River landscape in Wyoming. The park has historical significance, having been developed by the Civilian Conservation Corps (CCC) during the Great Depression. The name "Guernsey" comes from the nearby town, which is named after the Channel Island of Guernsey. The park features stone structures built by the CCC, including a museum and a castle, showcasing the craftsmanship of that era. Visitors can participate in a range of outdoor activities, such as camping, hiking on the old CCC trails, and exploring the stone museum and castle. Fishing and boating opportunities are also available on the reservoir, making it a popular spot for water recreation. Parking facilities are provided, and the park's remote location offers a tranquil retreat into nature. It is recommended that visitors confirm details regarding hours, fees, and any potential closures with the official state site before their visit.
