Seasonal Park Access

Operating Hours & Seasons in Rocky Mountain National Park

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.

Winter Closures

During the winter season, Trail Ridge Road which connects the parks east and west sides, is closed due to snow. Bear Lake Road, the park’s other major road on the east side, remains open year-round.
