Operating Hours & Seasons
Rocky Mountain National Park is open 24 hours a day, 365 days a year. Visitors can enter or exit at any time. Keep in mind that during the fall, winter, and spring, conditions can change quickly in the mountains. Be sure to check the status of park roads, as some roads close seasonally. Park visitor center hours also vary with the season. Summer and fall are typically the busiest times to visit the park. If you are planning to camp overnight in the park, you must be in one of the designated campgrounds or a backcountry campsite. Camping reservations are strongly recommended during the summer and fall.
