The Slide and Keekwulee Falls - 4.0 Miles Round-Trip

The Denny Creek Trail runs deep into the Alpine Lakes backcountry with access to Melakwa Lake and Snow Lake. There are two intermediate destinations along the way ideal for shorter day trips and families - The Slide (1.3 miles) and Keekwulee Falls (2.0 miles).

Trail Map | Photo Gallery

The Slide is an area where cascading water pours over smooth rock slabs and fills natural rock pools along Denny Creek. Keekwulee Falls is a 70' cascade located .7 miles ahead with great views down the valley. Both are easily reached and a perfect respite on hot summer days:

The trail follows Denny Creek north from the trailhead before veering NW across a bridge (.4 miles) and passing under the I-90 viaduct (.65 miles) to the ALW Boundary (1.0 miles : 2,575').

It runs under a tall canopy to stairs that lead down to the The Slide (1.3 miles : 2,690'), where gushing water spills over smooth rock slabs and fills natural stone pools along the creek. Exercise caution while exploring this deceptively slick area.

The trail rock-hops Denny Creek to the west side (1.5 miles), a cross that can be impassable at high water. Once over long switchbacks steer the trail south, then west, up fully exposed rockslides (1.7 miles).

It clears these uneven slide paths to great views of Keekwulee Falls, which pour 70’ over an exposed geometric chunk of granite (2.0 miles : 3,133’).
