Cross Ranch State Park

Tucked along a largely undeveloped stretch of the upper Missouri River in central North Dakota, Cross Ranch State Park protects one of the last free-flowing segments of the river alongside native mixed-grass prairie that looks much as it did centuries ago. The park sits adjacent to The Nature Conservancy’s Cross Ranch Preserve, and together the two properties form a corridor where bison roam, cottonwood forests line the riverbanks, and the pressures of modern development feel genuinely far away. For visitors who want wild prairie and river country without the crowds, this park delivers something increasingly rare in the Great Plains.

Bison Prairie and the TNC Self-Guided Trail

The defining experience at Cross Ranch is walking through active bison range on the TNC Self-Guided Prairie Trail, a partnership feature that gives visitors direct access to the Nature Conservancy’s managed herd. This is not a zoo or a fenced overlook. Bison move freely through this landscape, and encounters on the trail are real and require real attention. The prairie itself is stunning in the way flat, open land can be when it’s healthy, rolling through grasses, wildflowers, and bluff edges with long views toward the river valley below. The trail system within and around the park covers approximately 16 miles total, ranging from short interpretive walks to longer routes that connect riparian cottonwood bottoms with upland prairie terrain.

The Missouri River Corridor

The Missouri at Cross Ranch still behaves like a river rather than a reservoir. This stretch was spared the impoundment that transformed much of the river in the Dakotas, and it remains sinuous, wooded along its banks, and surprisingly quiet. Canoe and kayak access is available, making a float through this corridor a genuine wilderness-adjacent experience. Anglers fish for catfish, northern pike, and other Missouri River species from the banks or by water. The cottonwood floodplain along the river provides habitat unlike anything on the surrounding prairie, and walking the lower trails through this zone gives the park a layered quality, moving between two distinct ecosystems within a single visit.

Camping Along the River

Cross Ranch offers camping with immediate access to the river corridor and trail system. Sites are available for tents and RVs, and the setting is considerably more remote in character than many state park campgrounds in the region. Campers wake to deer moving through the tree line, turkeys picking through the grass, and mornings that feel genuinely removed from the highway. Reservations are recommended during peak summer weekends and can be made through the state park system. The campground serves as a practical base for multi-day exploration of the trail network or for paddlers doing extended Missouri River trips.

Pet Policy

Leashed pets are allowed in Cross Ranch State Park areas, but pets are not allowed on The Nature Conservancy preserve/TNC Self-Guided Prairie Trail except for service animals and limited hunting-dog exceptions. This applies to the campground and day-use areas within the state park. Do not bring pets onto the TNC Prairie Trail/Cross Ranch Preserve, except service animals and limited permitted hunting-dog exceptions. A dog reacting to bison creates a dangerous situation for the animal, the owner, and potentially other visitors.

Wildlife to Be Aware Of

Bison are present on and near the TNC Self-Guided Prairie Trail, and they are wild animals capable of moving quickly and unpredictably. Keep a safe distance from bison, do not approach them, and follow current posted park/TNC guidance. Do not approach bison to photograph them, and if a bison is blocking the trail, wait at a safe distance or turn back. Never position yourself between a cow and her calf.

White-tailed deer and wild turkey are common throughout the park and are most active at dawn and dusk. They are generally not dangerous but can startle unexpectedly near campsites and on wooded trails. Drivers should be alert on the park road during low-light hours, as deer crossing is frequent.

Rattlesnakes are possible in rocky prairie areas and along the bluff edges where warm, exposed surfaces attract them. Watch where you step and where you place your hands when scrambling or sitting on rocks. Snakes encountered on the trail should be given space and left alone. Wearing closed-toe shoes on all trails is strongly advised.

Practical Information

Cross Ranch State Park is located near the town of Washburn, North Dakota, roughly 35 miles north of Mandan via Highway 1806 or accessible from the east via Highway 200 and local county roads. The park address and turn-by-turn directions are available through the North Dakota Parks and Recreation Department. The GPS coordinates for Cross Ranch State Park are approximately 47.2135, -100.9996.

A daily vehicle permit is required for entry. An annual North Dakota state parks pass is also available and covers entry to all state parks in the system. For current pricing on both options, visit parkrec.nd.gov.

The park is open year-round, though services are reduced outside the summer season. Trails can be muddy or icy depending on conditions. Campground reservations are made through the state park reservation system. Cell service in the area is limited, so downloading maps and confirming details before arrival is a good idea.
