Dispersed camping near Guernsey, Wyoming offers opportunities for primitive overnight stays along various water features in southeastern Wyoming at elevations between 4,400-4,800 feet. The area experiences temperature swings between seasons, with summer highs reaching 90°F and winter temperatures frequently dropping below freezing. Multiple reservoir access points provide shoreline camping without developed facilities, though bathroom access varies by location.
What to do
Fishing opportunities: Gates 1-5 at Grayrocks Reservoir Public Access Area accommodate smaller vehicles and offer shoreline fishing. "Lots of other campers in view but not bothered by anyone! we had our own private beach," notes Jason & Sara S. The reservoir supports various fish species accessible from multiple shore points.
Water recreation: Shoreline access for swimming and paddling varies seasonally. At Wheatland Reservoir #1 - Public Access Area, "There are large fish (about a foot long or more) that splash along the shoreline. A few bow fishermen were there to try their luck," shares Cat R. Water levels fluctuate throughout the year affecting launch accessibility.
Wildlife observation: Early mornings provide opportunities for spotting pronghorn antelope, mule deer, and various bird species. "Cows everywhere, water close by and beautiful hills around this area," reports Rory R. about the landscape at Grayrocks Reservoir. Dawn and dusk offer prime wildlife viewing times across all sites.
What campers like
Privacy options: Many campers appreciate the ability to find secluded spots despite popularity. "We found a spot right on the lakeside which was secluded from everyone," notes Kyle G. at Grayrocks Reservoir. Driving further from main entrances typically yields more isolated campsites.
Scenic views: The reservoirs provide panoramic landscapes particularly during sunrise and sunset. Scott B. describes Wheatland Reservoir #1 as "Absolutely beautiful...the reservoir is beautiful and the sun rises and sunsets are gorgeous." The open terrain creates unobstructed viewing opportunities.
Accessibility: Most areas feature reasonable access roads for standard vehicles. "Easy access into campgrounds, good view of the lake, nice level camping spots for tents and smaller campers," explains Justin R. about Grayrocks. However, larger rigs should note accessibility constraints with Alison C. advising, "Gates 1-5 are very tight if you've got a large rig. Gate 6 and the loops nearest are the best for large RV's."
What you should know
Seasonal conditions: Weather changes rapidly with strong winds common across all sites. "Check the weather before you go!!!" warns Jason & Sara S. about Grayrocks. Summer temperatures can exceed 90°F while spring and fall bring unpredictable conditions.
Bug presence: Insects vary by location and season. At Grayrocks Reservoir, Avery O. reports, "The mosquitos were present but didn't bite much. The flies were definitely biting but nothing pants and a sweatshirt can't fix!" Rory R. more emphatically notes the "FLIES!!!! But amazing spot!! Cows everywhere, water close by and beautiful hills around this area. Only downside is the insane amount of flies."
Water conditions: Water quality requires attention before recreational use. Some visitors have reported bacteria warnings at Grayrocks Reservoir, with Avery O. noting, "Beware of the water. There was some sort of bacteria warning when we visited."
Tips for camping with families
Site selection: For shade protection, seek tree-covered areas at select locations. Cat R. notes about Wheatland Reservoir #1: "Plenty of spots around the water. Lots of trees for shade. I spent a restful 2 nights." Most primitive camping near Guernsey features limited natural shade.
Timing considerations: Weekend crowds require Thursday or Friday arrival for prime spots. Mackenzie D. shares about Grayrocks: "We got in around 6pm and the first few sites were full, only had to drive in about 10-15 to find an open spot that worked for us!"
Pet safety: Monitor pets closely due to environmental hazards. Kyle G. notes fire restrictions requiring alternative cooking methods: "Be advised as of jun 2025 no fires are permitted. Bring propane gas cookers, or cook in your camper/RV." Additionally, watch for foxtail plants which pose risks to dogs.
Tips from RVers
Road conditions: Access routes vary in maintenance quality. Mackenzie D. describes the approach to Grayrocks Reservoir: "We took a gravel road in from Fort Laramie. The road in is about 10 miles of unpaved gravel, totally fine for my SUV. We drove by cattle crossing the road but they were kind and slowly crossed for us to get by."
Site navigation: Clear signage helps identify boundaries between public and private land. Zabion P. notes: "Everything is pretty well marked with signs to tell what's camping and what's private property." Shore access conditions can change with Sharrie T. reporting about Wheatland Reservoir #1: "The water level is low so muddy walking out to the shore. Beautiful! Windy some of the time. Only a few campers."
Shore access: Reservoir levels affect site availability and shore conditions. Sherri S. describes Grayrocks: "This place offers waterfront camping with beautiful views and plenty of privacy from other campers." Arrive prepared for varying shoreline conditions depending on season and recent precipitation patterns.
