Heather-Maple Pass Loop

Overview

This is the classic Highway 20 loop you’ve seen in photos: a roughly 7.2-mile total loop with about 2,000–2,162 feet of gain to a 6,650-foot high point. It’s popular for good reason—varied terrain, big alpine vistas, and a true “top of the world” ridge walk. Expect a moderately hard effort for most hikers and plan on 4–5 hours, more if you linger for photos or tack on side trips.

Route Choices: Clockwise vs. Counterclockwise

Most hikers go counterclockwise for a gradual, view-filled climb over Lake Ann to Maple Pass, then finish with a steeper forested descent (tougher on knees). Clockwise flips the script—steeper early climb through woods, then a more forgiving descent. Choose CCW for the drama and flow; go CW if you prefer to climb the steeps and descend easier.

What You’ll See

You’ll start with forested switchbacks, then break into meadows that pop with wildflowers as the snow melts (often July). Lake Ann steals the show from multiple angles, and a short, mostly flat spur leads to its shoreline for reflections and a snack-worthy pause. Higher up, the ridge delivers panoramic views of the North Cascades, including Black Peak and Corteo Peak. Come late September into early October, golden larches electrify the slopes—arguably the best larch show in the state. Keep an eye out for marmots chattering along the talus and grouse in the meadows.

Best Time to Hike

July through September is your safest window for snow-free travel (snow can linger into mid-July some years). Late September to early October is prime for larches, with cooler temps and a real chance of early snow—spectacular, but bring layers and be ready. This loop is extremely popular, especially during larch season; start at dawn or go midweek to dodge peak crowds. Highway 20 can close due to seasonal conditions; always check road status before you go.

Permits, Parking, and Facilities

Start at Rainy Pass Trailhead off Highway 20. A Northwest Forest Pass or America the Beautiful pass is required to park. Vault toilets are available. The lot is large but fills early (often by mid-morning in summer and fall), with overflow along the highway where allowed. Occasional trailhead repair work can temporarily close the lot in September—verify current conditions before your trip.

Trail Notes and Tips

Poles are worth their weight on the steep, rocky/rooty descent, especially counterclockwise. Water is scarce along the ridge: carry plenty (2–3 liters in summer) and note there’s typically more flowing water on the Heather Pass side for filtering. Weather can change quickly—wind and chill are common at the pass. If snow lingers, traction may be prudent. Consider the short Lake Ann spur for a high-reward detour; Rainy Lake is another easy add-on from the same trailhead. From Heather Pass, strong parties sometimes extend toward Wing Lake and the Black Peak scramble, but that’s best treated as a separate, longer outing.

Pets

Dogs are not allowed on the high ridgeline section that crosses into North Cascades National Park. They’re permitted on leash up to Heather Pass (outside the park), but because the full loop enters park land, plan this one as a no-dogs hike if you intend to complete the circuit.
