"A timed entry reservation system will be implemented starting May 23, 2025. Two different timed permits will be offered: one that grants access to the entire park including the Bear Lake Road Corridor, and one that grants access to the rest of the park but excludes the Bear Lake Road Corridor. Reservations for access to the Bear Lake Road Corridor will be required from 5 a.m. to 6 p.m. through Oct. 20, while reservations for the rest of the park will be required from 9 a.m. to 2 p.m. through Oct. 14. Travelers will be able to enter within two-hour periods, with no set time for departure. Reservations are free except for a $2 Recreation.gov processing fee. The National Park Service wrote: “Some national parks use a timed entry system to manage vehicle traffic. Other parks use tour reservations to manage access to a building or natural feature,” and added, “If you need a reservation, we recommend making it well in advance.”" - Alison Fox Alison Fox Alison Fox is a Travel + Leisure contributor.
