About Denman Falls
Denman Falls is a quietly scenic cascade tucked inside Mount Rainier National Park and managed by the National Park Service. The falls tumble over rocky ledges into a fern-lined hollow, framed by dense forest that feels both lush and secluded. It’s the sort of place that rewards a camera and a slow, lingering pause — especially during spring and early summer runoff. Access is a moderate 2.5-mile out-and-back hike with about 400 feet of elevation gain, making Denman Falls an appealing half-day trip for families and day hikers seeking a peaceful waterfall within the park. The trail threads through old-growth forest and the final approach opens to a lovely viewpoint of the cascading water; come prepared for damp conditions after rain, and enjoy an inviting slice of Mount Rainier’s quieter backcountry.
The Setting
Denman Falls sits at 3,543 feet within Mount Rainier National Park, fed by the Puyallup River, in the mountains of Washington.
