What to Expect

The Heather Pass Trail wastes no time getting down to business. From the Maple Pass trailhead off Highway 20, you'll climb steadily through old-growth forest before breaking into the kind of alpine meadow that makes people move to the Pacific Northwest. The nearly 1,800 feet of elevation gain hits in waves — manageable stretches followed by steeper pitches that remind your lungs this is real mountain terrain. As you approach the pass, the trees thin out and the views crack open: Lake Ann sits below like a turquoise gem, while Black Peak and the surrounding North Cascades jagged ridgeline stretch out in every direction. In late July and August, the meadows explode with lupine, paintbrush, and heather (the trail earned its name honestly). This is a trail for hikers who want genuine alpine scenery without a multi-day commitment — all the grandeur of the high country packed into a solid half-day push.

Safety Advisory

The upper trail is fully exposed above treeline with no shelter. Weather in the North Cascades can shift from bluebird to whiteout in under an hour — carry a rain layer and extra warmth even on clear mornings.

Snow lingers on the pass well into July most years, and steep snow traverses without traction devices are a serious slip-and-fall hazard. Check recent trail reports before heading up and carry microspikes if there's any question.

There is no reliable water source on the upper half of the trail. Carry at least two liters per person — more on hot days, since the exposed alpine sections offer zero shade.

Pro Tips

Trail Tip

Start early — the Maple Pass trailhead lot fills by 8 AM on summer weekends, and there's no overflow parking. Weekdays are dramatically less crowded and the light is better for photos anyway.

Trail Tip

Bring trekking poles for the descent. The upper sections get loose and gravelly, and tired legs on steep downhill terrain is where most rolled ankles happen on this route.

Trail Tip

If you have energy to spare, extend the hike into a full Maple Pass loop (about 7.5 miles total) for a completely different perspective on the basin — the counterclockwise direction gives you the best views on the climb rather than saving them all for the end.
