What to Expect

Starting from the Fireweed trailhead on the east side of the North Cascades, this route climbs steadily through subalpine meadows and larch-dotted slopes toward Twisp Pass at just over 6,000 feet. The trail follows a classic Cascades pattern — dense forest gives way to wildflower parkland as you gain elevation, with increasingly dramatic views of craggy peaks and hanging glaciers. Dagger Lake sits in a rocky cirque below the pass, cold and clear, ringed by stunted conifers and talus. The pass itself delivers a sweeping panorama into the heart of the national park complex. This is a trail that rewards patience — the scenery builds gradually rather than hitting you all at once. Strong day hikers and backpackers looking for a less-trafficked entry into the North Cascades backcountry will find exactly what they came for.

Safety Advisory

Snow lingers on the pass well into July most years, and the final approach can be icy and exposed — traction devices and an ice axe are worth carrying before August.

The east side of the Cascades can be deceptively hot and dry in midsummer, with little shade on the upper stretches — carry more water than you think you need, as reliable sources thin out above treeline.

Pro Tips

Trail Tip

Approach from the Twisp River Road (east side) for the most gradual ascent — the west side drops steeply from the pass and adds significant elevation on the return.

Trail Tip

Late September through mid-October transforms the upper basin into a golden cathedral of larch trees — time your visit for peak larch season if you can tolerate cooler nights.

Trail Tip

Dagger Lake makes an excellent basecamp for exploring the surrounding ridgelines; arrive early enough to set up camp and scramble the slopes above the lake for sunset views back toward the pass.
