Rocky Mountain 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 or for safety. When necessary, park rangers will issue court citations to persons violating the terms of a closure.
