In short: Rising 14,410 feet above Washington, Mount Rainier is a glaciated icon that defines the landscape. While often viewed as a dormant giant, it remains an active volcano. Beyond its geological power, the park protects ancient forests and subalpine meadows, serving as a premier destination for climbers and nature enthusiasts alike.

Established on March 2, 1899, Mount Rainier National Park was the fifth national park in the United States. Its creation followed a five-year campaign led by figures like John Muir, who sought to protect the peak from the utilitarian 'conservation-through-use' policies of the era. To secure congressional approval, supporters had to guarantee that the land held no value for farming or mining and that the park would require no federal funding for its management.

The park spans 369 square miles, encompassing a stratovolcano that serves as the highest point in the Cascade Range. Its slopes are sculpted by more than 25 glaciers, including the Emmons Glacier, which is the largest by area in the contiguous United States. This icy environment creates a cool montane climate, with the Paradise area occasionally recording annual snowfall totals exceeding 80 feet. Below the timberline, the landscape transitions from dense forests of Douglas fir and western red cedar to vibrant subalpine and alpine meadows.

Archaeological evidence suggests the area was used by indigenous groups for hunting, gathering, and spirit quests for thousands of years, though there is no record of permanent habitation. Today, the park is a major hub for mountaineering, with approximately 10,000 summit attempts annually. It also stands as a historic site, featuring rustic-style architecture from the 1920s and 1930s, such as the renowned Paradise Inn, which earned the park a designation as a National Historic Landmark in 1997.
