Rocky National Park is open 24 hours a day year round. Visitors can enter or exit at any time. If they are planning to stay overnight, park visitors must be in a designated campground site or a backcountry campsite reserved by a valid permit. From time to time, the Superintendent implements area closures to protect resources. When necessary, Park Rangers will issue court citations to persons violating the terms of a closure.
