Mount Rainier National Park has officially announced that it will not implement a timed entry reservation system in 2026, ending months of speculation about whether the park would require advance reservations for visitors.
The decision makes Mount Rainier the fourth major national park to drop timed entry reservations for 2026, joining Arches National Park, Yosemite National Park, and Glacier National Park, all of which recently announced similar changes. Over the past several years, these parks experimented with reservation systems aimed at reducing crowding and traffic during peak visitation periods.
With these changes, Rocky Mountain National Park will remain the only major park continuing a broad timed entry reservation system in 2026. While some locations across the National Park System still require reservations—such as guided tours at Carlsbad Caverns National Park or permits for specific roads and trails—most of the large-scale timed entry experiments appear to be winding down.
Instead of requiring reservations, Mount Rainier National Park officials say they will rely on parking management strategies to manage visitor demand and maximize the number of people who can access the park.
Visitors planning a Mount Rainier National Park visit in 2026 should be prepared for busy conditions and have backup plans. Park officials recommend arriving before 7 a.m. or after 4 p.m., visiting on weekdays when possible, and considering lesser-known trails and areas if popular parking areas fill up.
Travelers should also identify alternative destinations within the park ahead of time in case their preferred parking area reaches capacity.
While the shift away from reservations will make spontaneous visits easier, it also means visitors should expect peak-season crowds at one of Washington’s most popular national parks.
