Located along seven miles of the last free-flowing, undeveloped stretches of the Missouri River, North Dakota's Cross Ranch Centennial State Park is rich in both cultural and natural history. The park is purposely left in its pristine state to preserve the land's natural beauty. The River Peoples Visitor Center features displays and dispenses information about the once mighty Missouri, which has now been tamed through a series of major dams and reservoirs along its length. A boat ramp is available for those wishing to explore this scenic segment of the river, while anglers will find walleye, pike and bass in its waters. An extensive trail system can be explored either on foot or on cross country skies during the winter months. During the summer, the trails allow access to a 5,000-acre dedicated nature preserve where mixed grass prairie, river bottom forests and woody draws can be seen. A back country area is open for those wishing to hike to their camping spot.
