Memorial Day weekend marks the beginning of the timed entry pilot program for Mount Rainier National Park. The program is being tested after the park saw an approximate 40% increase in visitation over the past decade, which has led to overcrowding during the summer and damage to ecosystems. Timed entry reservations are only required to enter the Paradise Corridor May 24 through Sept. 2 and the Sunrise Corridor July 4 through Sept. 2 for the hours of 7 a.m. to 3 p.m. Paradise is accessed through the Nisqually Entrance or Stevens Canyon Entrance. Sunrise is entered through the White River Entrance.
