Otter Falls

About Otter Falls

Otter Falls (also called Otter Slide, Otter Slide Falls or Otter Creek Falls) tumbles down the southern wall of Mount Anderson in King County, Washington, within the Alpine Lakes Wilderness. Managed by the U.S. Forest Service as part of Snoqualmie National Forest, the falls have a cumulative drop of about 1,600 feet, though the mountainside’s moderate pitch means only roughly a third of that height is visible from the valley floor. The creek’s drainage is fairly small and runs mostly over granite that doesn’t retain water, so flow can be modest outside peak snowmelt—making for dramatic granite slides and photogenic cascades when conditions are right. The trailhead approach follows forested terrain along the Taylor River and uses sections of the USFS NORDRUM LAKE (Trail #1004). Expect a moderately challenging backcountry outing: the route to Otter Falls is typically done as a 9.0-mile out-and-back with about 700 feet of elevation gain and is rated moderate. If you’re camping, Middle Fork Campground is the closest option at roughly 7.1 km away, and the entire area is managed by the USFS, so plan for wilderness conditions and variable water flow.
