Twisp Pass Trail

Overview

Twisp Pass is a classic North Cascades walk with big variety: river-bottom forest, avalanche chutes, a pretty lake, and a broad, view-soaked pass. From the west (inside the park) it’s a long out-and-back that rewards the effort with quieter miles and standout autumn color. Expect about 16.6 miles total (out and back) via the Bridge Creek corridor with a connector stretch on the PCT and a side trip past Dagger Lake. This is a full-day hike for most, and it feels remote—in a good way.

The Route(s)

• West (in the park): Start near SR 20 and follow the PCT corridor about 3.4 miles to the Twisp Pass junction, cross Bridge Creek on a single-log bridge, pass signed camps, then climb steadily past brushy avalanche chutes. Dagger Lake sits just below the pass; continue to Twisp Pass for the wide-open payoff. This version runs roughly 7.6 miles one way to the pass, around 15–16.6 miles round trip depending on mapping and any explorations.
• East (from Twisp River Road, outside the park): A shorter, steeper climb on an old mining road-turned-trail with early forest/meadow walking, a log bridge over the North Fork of the Twisp River, and historic rock cribwork. This reaches the same pass from the national forest side. Note: pets allowed up to the park boundary only.

What You’ll See

Expect classic North Cascades textures: granite outcrops, stunted hemlocks and wildflower meadows near the crest, and a shallow, photogenic Dagger Lake tucked against rugged peaks. In fall, the color show is real—golden larches, red blueberry, orange mountain ash, and yellow maples. From the pass, broad views range to Lincoln Butte and Twisp Mountain with room to roam and linger.

Trail Feel and Difficulty

This is a long day from the west, with an early descent to the valley before the main climb—remember you’ll pay that back on the return. Tread is generally good but can be rocky and brushy. The avalanche debris field and chutes on the west side slow travel, and single-log bridges demand attention. The pass itself is gentle and inviting—bring a wind layer and plan time to enjoy it.

Water, Bugs, and Camping

Water is available near major creeks and at Dagger Lake, but plan ahead: carry capacity for the longer, drier stretches, and prioritize flowing sources when possible. Mid-summer mosquitoes can be fierce, especially near Dagger Lake—long sleeves and real repellent help. Backcountry permits are required for any overnight stay within the park. Campfires are not allowed at Stiletto Lake, and Stiletto is closed to stock.

Regulations and Access

A federal recreation pass is required to park at the primary trailheads used to access this route. Pets and hunting are not allowed within the national park; Twisp Pass effectively marks the boundary from the east. Overnight trips require a park backcountry permit; designated sites near Dagger Lake are limited.

Best Time to Hike

June through October is the typical window. Early summer brings flowers and lingering snow patches; midsummer is green and buggy; late September into early October is prime for larches and vivid shrubs. Start early for cooler temps, easier parking, and forgiving light in the avalanche chutes. Weekdays and shoulder-season days see the fewest people.

Bottom Line

If you’re up for the mileage, the west-side approach delivers a rich sampler of the North Cascades—quiet miles, a jewel of a lake, and a pass you won’t want to leave. Want shorter? Approach from Twisp River Road—but remember the no-pets rule inside the park if you plan to cross the boundary.
