However, because weather conditions may change rapidly at higher elevations, park visitors should be prepared to adjust travel plans accordingly at any time and are encouraged to call the park’s Trail Ridge Road recorded status phone line at (970) 586-1222. Park staff will update the recorded line when/if the road status changes.

Timed Entry Permit Reservations Effective Friday, May 26

Rocky Mountain National Park is implementing a pilot timed entry permit reservation system which will begin tomorrow, May 26. Rocky Mountain National Park is one of the busiest national parks in the country, with over 4.3 million visitors in 2022. Visitor crowding and congestion have led to increased negative impacts to visitor and staff safety, resource protection, visitor experience and operational capacity. The park has piloted various visitor use management strategies since 2016, including first-come, first-served as well as different parkwide Timed Entry Permit Reservation system pilots since 2020.

In 2023, there are two types of reservations available. One permit is for the Bear Lake Road Corridor, which includes the entire corridor and access to the rest of the park. This reservation period is from 5 a.m. to 6 p.m. The second permit is for the rest of Rocky Mountain National Park, excluding the Bear Lake Road corridor, and includes Trail Ridge Road. This reservation period is from 9 a.m. to 2 p.m. Permits issued using the reservation system will allow park visitors to enter the park within two-hour windows of availability. The reservation system will apply to all areas of the park. To learn more visit
