Twisp Pass Trail
Twisp Pass Trail is a remote hiking route in Washington’s North Cascades, using a mix of forest travel, avalanche terrain, and open rocky ground to reach Twisp Pass and connect into the broader network of informal trails around the pass. The route is generally approached as an out-and-back from the east or as a longer western approach tied to the Pacific Crest Trail.
Two common ways into the route are from the Gilbert Trailhead off Twisp River Road (eastern approach) or via the Pacific Crest Trail from Highway 20 (western approach using Bridge Creek Trail to connect over to Twisp Pass Trail). In both cases, expect a serious backcountry feel rather than a maintained footpath: heavy brush and occasional downed trees are part of the hiking reality, and route-finding matters.
From the lower valley, the trail gradually climbs through subalpine forest toward the pass. Just below the high point, avalanche effects show up as debris fields and choked-looking chutes, followed by rocky meadows and the final ascent into the forested saddle at Twisp Pass.
The length and effort depend on which side you come from and where you turn around. A typical eastern out-and-back is described around 10 miles total, with elevation gain in the 3,000–4,700 ft range based on your turnaround point; the western approach is longer and is often run as a backpacking day with a roundtrip closer to the mid-teens in miles.
Overnight use is managed through backcountry permitting in the North Cascades National Park portion of the route. Expect limited permits, and plan camping options around the Dagger Lake area (including hiker and stock camps) if your itinerary takes you that far.
Pass seasonality is tied closely to snow and avalanche cycle timing: early summer supports flower displays in the avalanche terrain; late-season conditions commonly include fall colors and larch. In bug season, the area near Dagger Lake is known for mosquitoes, so late-season and mid-summer starts should be planned with repellent and long-sleeve layering in mind.
