Guernsey State Park sits at 4,500 feet elevation in southeastern Wyoming, where dramatic sandstone cliffs meet the North Platte River. The park's reservoir fluctuates seasonally with water levels typically highest in early summer before irrigation releases begin. Winter temperatures can drop below freezing, but the park's four all-season yurts provide year-round accommodation options.
What to do
Water sports during silt run: Mid-July brings a unique opportunity at Guernsey State Park Campground when the silt run occurs. "The best time we had here was during the silt run, which is in mid-July each year. Water being released from Glendo Reservoir will flow through Guernsey Reservoir flushing silt into the canals of downstream irrigators," notes Sarah N. The reservoir drops about 25 feet, creating muddy conditions that transform the recreation experience.
Hiking trails: The park features multiple trail systems with varying difficulty levels. "Cool hiking trails, fun biking trails, good place to explore history," comments Amanda T. For panoramic views, Brimmer's Point is particularly recommended, offering sweeping vistas of the reservoir and surrounding landscape.
Historical exploration: The area surrounding Guernsey is rich with pioneer history. "Nice for boating and swimming activities. Stayed at Sandy point loop," shares one visitor to Sandy Beach Dune and Willow. When water levels are low, visitors can see exposed geological features and historical markers that are normally underwater.
What campers like
Privacy and site spacing: Campsites throughout Guernsey State Park offer varying levels of seclusion. "Forested; private sites available. Interesting history/museum. Some short trails. Bring bug spray," recommends Melanie Z. Site selection can significantly impact your glamping experience in Guernsey, Wyoming.
Reservoir views: Many campsites provide direct views of the water. "Easy access and views of the lake," notes a visitor. The lakeside setting creates opportunities for both recreation and relaxation, with sandy beaches that stretch for nearly two miles when water levels permit.
Multiple camping loops: Douglas KOA, located about an hour from Guernsey, offers additional lodging options including cabins and yurts. "There are ample amount of RV and tent sites. They offer cable and WiFi," writes Shannon G. The property includes amenities like putt-putt golf for $2, tennis courts, basketball facilities, and a swimming pool.
What you should know
Seasonal water fluctuations: The reservoir level varies dramatically throughout the year. "While I imagine this place is fantastic for everything from water skiing and fishing to party boating along the river (with various launch points) it is highly dependent on the water level," cautions Daniel B. Call ahead to check current water conditions, especially during late summer.
Bathroom availability: Facility maintenance varies by season. "My only complaint is that the showerhouse is closed! I wish it had stated that on the website, it said it was open as of April 15th but they haven't turned the water on yet," reports Nicole B. at Guernsey State Park Campground.
Train noise: Several campgrounds in the region experience railroad noise. "This camp site is not ideal for those who want a camp site away from it all... My camp site was near a very active railroad track," warns Jessica M. Light sleepers should consider bringing earplugs, especially when staying in sites near the tracks.
Tips for camping with families
Bug preparation: Insects can be prevalent, particularly in warmer months. "When we got to the campsite on the beach we were so excited! Walked out to put our stuff down, and looking at the ground it was OVERRUN with giant ants!" warns a camper at Sandy Beach Dune and Willow. Pack insect repellent and consider setting up tents away from tree bases.
Military training awareness: The park sits near National Guard training grounds. "You might be able to hear the artillery of the National Guard practice area when they are active - which is most of the summer," advises a yurt camper. This information is particularly important for families with young children or pets that might be sensitive to loud noises.
Activity planning: Beyond water recreation, consider alternative activities for when water levels are low. "There is a Jackalope Square that has Farmers Market on Saturday's that has a huge statute of said Jackalope," notes a visitor to City Slickers RV Park, which offers a convenient base for exploring regional attractions.
Tips from RVers
Power availability: Electric sites are limited at some campgrounds in the area. "Sandy Beach Willow campground one of the only two sites with power but no water," reports Karen L. Reserve well in advance if hookups are needed, especially during summer months.
Firewood regulations: Fire restrictions vary seasonally and by location. "As there is a fire ban right now there were no fire rings," notes a visitor to Douglas KOA. Check current fire regulations before arrival, and remember to purchase firewood locally to prevent spreading invasive species.
RV site selection: For larger rigs, certain areas work better than others. "Although it was affordable for our 25 foot 5er, we barely fit in our assigned spot length wise," comments an RVer at Douglas KOA. Call ahead to confirm site dimensions if traveling with larger recreational vehicles, as many of the older campgrounds weren't designed for today's bigger RVs.
