Trek to a pair of pristine alpine lakes hidden deep in the spectacular Selkirk Mountains.

From the dirt pullout off Forest Road 663, pick up Two Mouths Trail #268 as it meanders north along an old logging road. Swing to the west as the trail traces Peak Creek before bending back to the south. The trail narrows and alternates between dirt and boardwalk while swinging west toward a viewpoint of the granite-faced Selkirk Crest, which you’ll peak at mile 3.6. From the top of the Crest, notch spectacular vistas of glacier-carved peaks to the north and down-valley views toward Bonners Ferry to the east.
Drop into the boulder-blasted marshlands to the east before forking right toward Lower Two Mouth Lake. Pass by campsites along the lake’s pristine eastern shore before following a spring-fed creek south to the upper lake. The upper lake is wider and deeper, but its shoreline is shrouded by trees and sweeping slabs of granite. Several campsites dot the lake’s shoreline, but only one sits directly on the water. Return to the trailhead via the route you hiked in on.
