Another season of reservations is on the horizon at Rocky Mountain National Park.

Starting May 24 through mid-October, the park is returning its time entry system. Slots are already booking at Recreation.gov for visits between May 24-June 30.

Reservations for July will open June 1, with reservations for August opening July 1 and so forth. Recreation.gov charges a $2 processing fee. Visitors will also have to show a season pass or pay the park’s entry fee ($30 per vehicle).

Visitors choose from two permits. One allows access to all parts of the park except the popular Bear Lake Road corridor; this “rest of the park” access is allowed without a reservation before 9 a.m. and after 2 p.m. To reach Bear Lake Road, reservations are required from 5 a.m.-6 p.m.

In slight changes from years past, 40% of all available permits will be released on Recreation.gov at 7 p.m. the night before a desired visit.

The timed entry system started in 2020 in a stated effort to control record crowds at one of America’s five most-visited national parks.

Since a record 4.6 million visitors in 2019, Rocky Mountain National Park has reported steady dips year to year. The 4.1 million tallied in 2023 were the lowest since 2015, though still ranking atop visitation charts with Great Smoky Mountains, Grand Canyon, Zion and Yellowstone.

During the busy season, the timed entry system is said to allocate for 90% of the park’s max capacity, spreading out up to 20,000 visitors a day, or 7,200 vehicles over a 24-hour period.

Permits for Bear Lake Road will be required through Oct. 20, with the “rest of the park” permits ending after Oct. 14.
