Why Visit Guernsey State Park
Guernsey State Park, Wyoming, is a gem in the heart of the Cowboy State, offering a unique blend of natural beauty, outdoor recreation, and fascinating history. What truly sets this 6,000-acre park apart are its remarkable Civilian Conservation Corps (CCC)-built structures, which earned it a designation as a National Historic Landmark in 1997.
As you explore the park, you’ll encounter magnificent examples of rustic architecture, crafted from local sandstone with hand-forged iron and hand-hewn logs by young men during the Great Depression. These structures, including the iconic Castle, the Guernsey Museum, and numerous picnic shelters, seamlessly blend into the rugged landscape, offering both functionality and breathtaking views.
Beyond its historical significance, Guernsey State Park provides a haven for outdoor enthusiasts. The Guernsey Reservoir, encompassing 2,400 surface acres, is a focal point for water-based activities like boating, fishing, and swimming. The park's rugged and scenic terrain also features an extensive network of hiking and biking trails, offering panoramic vistas of the reservoir, the North Platte River Canyon, and the surrounding Laramie Range.

Top Things to Do
Guernsey State Park offers a wealth of activities, ensuring there are plenty of things to do at Guernsey State Park for every visitor. Our team highlights these essential experiences:
Explore the CCC Structures
The park is renowned for its exceptional Civilian Conservation Corps (CCC) architecture, which dates back to the 1930s. These historic sandstone and timber buildings are not just relics; they are integral parts of the park experience. Don't miss:
- The Castle: This multi-level stone structure offers incredible views of the reservoir and surrounding landscape from its observation area. It features a giant fireplace and winding steps, inviting exploration.
- Guernsey Museum: Perched on a high cliff overlooking the water, the museum itself is a masterpiece of CCC craftsmanship, with hand-hewn timbers and flagstone floors. It houses exhibits on the area's natural and local history. The museum is open seasonally from May 1 through September 30.
- Brimmer Point: Offering panoramic views, Brimmer Point is another CCC-built overlook that provides excellent photo opportunities and a chance to appreciate the scale of the reservoir.
- Historic Picnic Shelters: Throughout the park, especially on the east side along Lake Side Drive, you'll find unique CCC-built picnic shelters, such as those at Sitting Bull, Red Cloud, and Spotted Tail campgrounds, perfect for a scenic meal.
Boating and Water Recreation
Guernsey Reservoir is a hub for water activities, offering 2,400 acres for enjoyment. Boating is permitted across the entire reservoir as water levels allow.
- Boat Launches: Access points are available at Sandy Beach, the main boat launch on the southeast end, and Long Canyon ramp on the north end.
- Water Sports: Beyond leisurely cruises, the reservoir is popular for water skiing and swimming.
- **Important Silt Run Information (2026):** Visitors should be aware of the annual silt run, typically occurring after July 4th. In 2026, reservoir levels are expected to drop significantly from July 5th to July 10th, making boat ramps unusable by July 8th. The silt run is scheduled from July 11th to July 24th, with refilling beginning July 24th and boating expected to resume around July 27th. Normal levels are anticipated by July 29th. Low water levels are also generally expected at several Wyoming reservoir state parks, including Guernsey, during the 2026 summer season due to drought conditions.
- **Harmful Cyanobacteria Bloom (HCB) Advisory (2026):** As of June 19, 2026, a recreational use BLOOM ADVISORY has been issued for Guernsey Reservoir. Visitors should avoid contact with water in the vicinity of the bloom, not ingest water, rinse fish with clean water (eating only the fillet), and prevent pets/livestock from drinking or contacting the water.
Before heading out on the water, ensure your boat has been inspected for Aquatic Invasive Species (AIS) at one of the designated locations near Cheyenne, Glendo Reservoir, Manville Check Station, or Torrington Port of Entry, as there are no AIS inspection locations in Guernsey.
Fishing
Anglers will find walleye, yellow perch, and channel catfish in Guernsey Reservoir. Fishing is permitted subject to Wyoming Game and Fish Commission regulations. No fishing is allowed within 20 yards of any boat ramp, dock, or designated beach area. The reservoir is drawn down twice a year, which can affect fish populations. For 2026, updates to Wyoming Game and Fish's Chapter 46 fishing regulations took effect on January 1st, so we advise checking the official Wyoming Game and Fish Department website for the most current rules.
Camping
With 19 campgrounds and 250 campsites, Guernsey State Park is a fantastic place to pitch a tent or park an RV. All campgrounds offer comfort stations, picnic tables, and fire grills. Reservations for regular campsites are accepted for arrival dates between May 1st and September 30th, four months in advance. Yurts are also available for reservation from April 16th to October 14th. Quiet hours are from 10 p.m. to 6 a.m.

Picnicking
Guernsey State Park has numerous picnic areas, including many historic CCC-built shelters, picnic tables, and fire rings throughout the park. These are available year-round and are perfect for a relaxing outdoor meal.
Historical Sites Nearby
Beyond the park's boundaries, the immediate area holds significant historical weight. The Oregon Trail Ruts and Register Cliff are located just a short distance from Guernsey. These sites offer a tangible connection to the pioneers who traveled west, with visible wagon ruts and names carved into the cliff face. Fort Laramie National Historic Site, a former fur trading post and military fort, is also a short drive away, providing further insight into western settlement and Native American history.
Guernsey State Park Hiking Trails
The Guernsey State Park hiking trails are a highlight for many visitors, offering a unique blend of natural beauty and historical significance. The Civilian Conservation Corps (CCC) originally designed and built an extensive network of trails in the 1930s, and approximately 14 miles of these historic trails have been restored and are available for public use today.
Most of the Guernsey State Park hiking trails are located on the west side of the reservoir. A trail kiosk with a map of the system can be found at the trailhead near the turn-off to the Brimmer Point Overlook, serving as an excellent starting point for your adventure. The trail system is comprised of several loops, providing varied scenic views of the park, the reservoir, and the Guernsey Dam.
Many of these trails are considered moderately physically demanding, with rocky terrain, so we recommend sturdy hiking shoes over sneakers. Always carry water and be prepared for sun and wind, regardless of the season. While trail signage can sometimes be challenging, the trail tread is generally visible, and cairns (rock piles) can help guide you.
Some notable trails and areas within the Guernsey State Park hiking trails system include:
- Peak View Trail: This 1.5-mile trail starts near the junction of Skyline Drive and Brimmer Point Drive, offering decent views and connecting to Newell Bay Trail and Davis Bay Trail. It's also suitable for mountain biking.
- Tunnel Mountain Trail: Known for its variety and as a good workout, this trail offers engaging terrain.
- Newell Bay Trail: This trail can be combined with Tunnel Mountain Trail for a 2.7-mile loop, cutting through interesting geological formations.
- Quarry Two Track: An old road leading to a quarry where the CCC blasted stone for their buildings, this loop offers a different perspective on the park's history and geology.
The trails are open year-round for hikers, mountain bikers, and equestrians, offering different experiences with the changing seasons. Spring and fall are particularly pleasant for hiking, with milder temperatures and beautiful scenery.
Best Time to Visit
Choosing the best time to visit Guernsey State Park depends largely on your preferred activities and tolerance for crowds and weather conditions. Our team has outlined the seasonal considerations:
Summer (June - August)
Pros: This is peak season for water recreation. Boating, swimming, and fishing are at their prime, and all park facilities, including the Guernsey Museum, are typically open. The weather is generally warm and sunny, perfect for enjoying the reservoir. Events like "Plein Air in the Parks" (June 24-28, 2026) may also take place.
Cons: Summer also brings the largest crowds, especially on weekends and holidays. More importantly, visitors planning water activities during the summer of 2026 must be aware of potential challenges. Wyoming State Parks is advising visitors to prepare for lower-than-normal water levels at Guernsey Reservoir due to ongoing drought conditions. Additionally, the annual "silt run" is scheduled from July 11-24, 2026, which will cause a rapid decline in reservoir levels (boat ramps unusable by July 8th) and restrict water recreation activities. A harmful cyanobacteria bloom (HCB) advisory was also issued for Guernsey Reservoir as of June 19, 2026, recommending avoiding water contact.
Spring (April - May) and Fall (September - October)
Pros: These shoulder seasons are often considered the best times for hiking the Guernsey State Park hiking trails, as temperatures are milder and the crowds are thinner. The scenery is beautiful, with spring wildflowers or vibrant fall foliage. The Guernsey Museum is open from May 1 through September 30. Camping reservations for regular sites also open May 1st.
Cons: Water levels in the reservoir might still be cool for swimming in spring, and boating might be less comfortable. Early spring can still bring unpredictable weather, including late snows or strong winds. Late fall can see facilities begin to close for the winter.
Winter (November - March)
Pros: For solitude and a unique perspective, winter can be beautiful. Hiking trails are open year-round. Wildlife viewing opportunities may increase as animals are more active. The park is much quieter, offering a peaceful escape.
Cons: Many park facilities, including the museum, are closed. Water recreation is not feasible, and some roads or areas might be inaccessible due to snow or ice. Winter sports are possible, but the primary draw of water activities is absent. Camping is available on a first-come, first-served basis outside the reservation season, but comfort stations may be limited.
Our team generally recommends late spring (May) or early fall (September) for the best balance of pleasant weather, open facilities, and fewer crowds, keeping in mind the 2026 silt run and low water advisories for summer. Always check the official Wyoming State Parks website for the latest conditions and advisories before your visit.
