Keyhole State Park Hiking Trails

For those who prefer to explore on foot, Keyhole State Park offers a couple of distinct hiking trails, allowing visitors to experience the diverse landscapes and wildlife of the area. We appreciate that the park caters to different fitness levels, ensuring that most visitors can enjoy a walk in nature.

The park features two primary Keyhole State Park hiking trails, both conveniently starting at the Park Headquarters.

• The Marina Trail: This is an easy, 1.5-mile concrete trail that runs from the Headquarters directly to the Keyhole Marina. It's a great option for a leisurely stroll, offering scenic views of the reservoir and easy access to the marina's amenities.
• The Cottonwood Trail: For a slightly more challenging experience, the Cottonwood Trail is 2.8 miles long. It also begins at the Headquarters and winds through the Homestead Campground to the Cottonwood Campground. This trail provides a deeper immersion into the park's natural environment.

While these Keyhole State Park hiking trails offer a good introduction to the park's terrestrial side, visitors should be aware of current conditions. As of June 2, 2026, Stage 2 Fire Restrictions are in place due to extreme fire danger, prohibiting all campfires. While hiking is still permitted, it's always wise to check for any specific trail closures or advisories at the Park Headquarters before setting out.

Best Time to Visit

The "best" time to visit Keyhole State Park truly depends on what you're hoping to experience, as each season offers its own unique charm and activities. Our team has broken down the year to help you decide:

• Summer (June-August): This is peak season for a reason. The weather is warm, perfect for all water sports like boating, swimming, and water skiing. All campgrounds are open, and the marina is fully operational, offering boat rentals. However, be prepared for crowds, especially on weekends and holidays. Reservations for camping are highly recommended during this period, as the camping season runs from May 15th to September 15th. Also, be aware that low water levels are expected during the 2026 summer season.
• Spring (April-May): Spring brings milder temperatures and blooming wildflowers, making it an excellent time for hiking and bird watching. The reservoir begins to thaw around late March to early May, allowing for boating. Crowds are thinner than in summer, offering a more peaceful experience. Camping outside the reservation season (before May 15th) is first-come, first-served.
• Fall (September-October): With cooler temperatures and vibrant fall foliage, this is an ideal time for hiking, fishing, and enjoying the serene beauty of the park. The marina typically closes at the end of September. Fishing remains excellent, and wildlife viewing opportunities increase as animals become more active. Camping outside the reservation season (after September 15th) is first-come, first-served.
• Winter (November-March): For those seeking solitude and unique outdoor experiences, winter at Keyhole State Park is magical. Ice covers the lake from October to December, making it a prime destination for ice fishing. Bird watching, particularly for bald eagles, is also popular. While many facilities may be closed, the park remains open year-round, and cabins in Tatanka are reservable.

Regardless of when you visit, always check the Wyoming State Parks website for current conditions, especially fire restrictions. As of June 2, 2026, Keyhole State Park has implemented Stage 2 Fire Restrictions, prohibiting all campfires.
