About Twin Falls
Twin Falls sits within Mount Rainier National Park and is managed by the National Park Service. The falls are an attractive stop for hikers exploring the park’s lower-elevation forest corridors, dropping through a series of scenic cascades framed by old-growth trees, mosses and ferns. The setting feels intimate and verdant — a classic Pacific Northwest waterfall experience inside a nationally protected landscape. The hike to the falls is approachable for most hikers: the out-and-back route covers about 3.6 miles round-trip with roughly 500 feet of elevation gain and is typically rated moderate. Trails are generally well-maintained, and the short distance makes Twin Falls a satisfying half-day outing for visitors to Mount Rainier National Park looking for water, forest ambience, and photo opportunities without a multi-day commitment.
The Setting
Twin Falls sits at 5,246 feet within Mount Rainier National Park, fed by the Cowlitz River, in the high mountains of Washington.
