Mount Rainier National Park encompasses 235,625 acres or 368 square miles. Of that amount, 228,480 acres (97% of the park) has been designated by Congress as Wilderness. The park's National Historic Landmark District includes 2.7% of the park. The park has over 260 miles of maintained trails and 147 miles of roads.
Geologists consider this mountain to be an 'episodically active' volcano, meaning one that will erupt again some time in the future even though it may be quiet now. Mount Rainier is the tallest volcano and fifth highest peak in the contiguous United States.
The place is covered in trees!
Congress established Mount Rainier National Park on March 2, 1899, reaffirming the nation's intent to set aside certain areas of outstanding scenic and scientific value for the enjoyment of present and future generations. It is America's fifth oldest national park, after Yellowstone (established in 1872), and Yosemite, General Grant (now part of Kings Canyon), and Sequoia (all established in 1890).
