Blue water, a wooded shoreline, and a broad sweep of Wyoming sky set the tone at Keyhole State Park. The reservoir gives the park its center of gravity: a place for a paddle, a swim, a fishing line dropped over the side of a boat, or simply an unhurried walk near the water.
The mood can be notably calm in the morning and afternoon, when the lake and its surrounding campsites invite a slower pace. Later, the beach is a fine place to settle in for the changing light; sunsets over the reservoir are among the park’s especially handsome moments.
Keyhole works for an afternoon drive as easily as it does for a multi-night camping stay. A day can move naturally from a shoreline trail to the dam, then into the canyon for a higher view across the valley and the dark-blue lake.
Camping in Several Different Settings
Camping is a major reason to come, and the range of choices is useful. The park has tent-oriented sites, rustic dry-camping areas, cabins, and more developed accommodations, with sections scattered among woods, near shorelines, and in spots that look out over the lake.
That variety gives the campground a less one-note character than a single loop of identical sites. Some campers will want the simple setup of a dry site and quick water access; others may prefer a cabin or a site with a more open lake view.
Several shoreline cabins offer a particularly pleasant arrangement, with water views and easy access to walks along the shore. They provide a comfortable middle ground for people who want the rhythm of a campground stay without pitching a tent.
Not every site has the same footprint or setup. Some tent sites can be small, some pads uneven, and certain sites involve a downhill walk. At some waterfront campsites, an access road sits between the site and the lake, so “near the water” can mean different things in different campground sections.
Utilities also vary. There are sites without power or water hookups, making it important to confirm the equipment and amenities attached to the specific reservation rather than assuming one campground loop matches another.
Clean restrooms are a welcome detail when the day has been spent in a kayak or on a trail. The park includes well-kept bathroom facilities and clean vault toilets, and at least one camping area has locking trash bins.
Water All Day Long
The reservoir is built for a choose-your-own-day approach. Boating, kayaking, swimming, and fishing all fit comfortably here, and the boat launch makes it easy for boaters to get from road to water without much ceremony.
A quiet beach can make a simple swimming stop feel surprisingly private. The shoreline has enough room to spread out, take a break from the campground, or just sit with a towel and watch the lake move in the breeze.
Fishing remains one of the park’s steady attractions, and the fish-cleaning station is a practical convenience after time on the water. In the river area, very large trout have been spotted—enough to make even a casual angler look twice.
The appeal is not limited to high-energy lake days. A chair near the shore, an early coffee at camp, and a little time watching boats cross the reservoir can fill an afternoon quite nicely.
A Short Walk Along the Lake
For a low-commitment hike, the Beach Trail follows the lake and can be paired with the Little Keyhole Trail near the dam. Together, they make a relaxed afternoon outing rather than an all-day undertaking.
The routes give walkers a way to see the reservoir at ground level, where shoreline curves, beach areas, and changing water views become the focus. They also work well between camp chores and dinner, when a longer expedition would be more effort than anyone wants.
The dam area adds a different visual note to the visit. From there, the park begins to open outward from a lakeside setting into the broader river-and-canyon landscape.
The Canyon Drive and the Curious River
A drive up the canyon provides a welcome change from the shoreline. The view broadens across the valley toward the reservoir, with the lake appearing dark blue against the surrounding terrain.
Along this road, the river has an unusual visual quirk: in one area it appears to sink away, then farther along the route it reappears. It is the sort of roadside detail that can turn a scenic drive into a string of small stops and closer looks.
Canyon viewpoints are especially useful for getting a sense of the park’s scale. From above, the reservoir is no longer just a place to launch a kayak or cool off at the beach; it becomes a long, blue presence in the valley.
Small Conveniences for a Long Day Outside
Covered picnic tables offer a practical place for lunch, a card game during a passing shower, or a lakeside dinner that does not require balancing plates on camp chairs. The park also has a playground, giving younger visitors a place to burn off energy away from the water.
The ranger station is worth including in the circuit of a park visit. It makes a natural stop between campground loops, beach time, and the dam area.
Showers may be some distance from a campsite. Coin-operated showers have been available, with cash or quarters needed, so that small detail is worth sorting out before the first sandy-footed return from the beach.
Reservations for campsites are available online and by phone rather than in person. The nearest gas station is a long drive away, so fuel, ice, and other essentials are best handled before settling into a campsite or heading out for a day on the reservoir.
