About Affi Falls
Tucked into the forested reaches of Mount Rainier National Park and managed by the National Park Service, Affi Falls is a quieter cascade that rewards visitors with a peaceful, woodsy setting. Its lesser-known status inside the park makes it a great option for hikers seeking solitude away from the busier viewpoints, where mossy trunks and shaded slopes frame the fall. Reaching the falls is a pleasant, half-day outing: the route is a moderate 2.4-mile out-and-back with about 350 feet of elevation gain, making Affi Falls accessible to most fit hikers who want a short but satisfying backcountry experience inside Mount Rainier National Park. As with any visit to a national park, plan according to NPS guidance and seasonal conditions.
The Setting
Affi Falls sits at 5,423 feet within Mount Rainier National Park, fed by the Huckleberry Creek, in the high mountains of Washington.
