A valid ticket or park pass is always required to enter Rocky Mountain National Park, 24 hours a day, 7 days a week. Like it or not, Rocky Mountain National Park's scheduled entry reservation policy is now in effect. Gone are the summer days, when you could visit the park at the right time, and they may be gone forever if park officials decide to make this summer's “pilot program” permanent. First of all, keep in mind that there are two types of reservations, and the times when they apply differ significantly.
Reservations are required starting at 5 a. m. If you want access to the popular Bear Lake Road corridor. Bear Lake Road offers access to many of the park's most popular destinations, including Glacier Basin, Sprague Lake, Bierstadt Lake, Glacier Gorge and Emerald Lake.
After passing through the front door, another guard station will be set up on Bear Lake Road, where park rangers will verify that you have the proper reservation to continue. A Bear Lake reservation also allows access to the rest of the park.
