Overview
The Mallard-Larkins Pioneer Area contains some of the most remote and pristine terrain in the southern St. Joe unit of Idaho Panhandle National Forests. This 10-mile out-and-back accesses the heart of the roadless zone, passing through old-growth cedar and spruce forest before climbing to mountain lakes at the edge of the high country. Wildlife is abundant: elk, black bear, and bull trout in the streams. Trail traffic is sparse even in peak season.
No permit is required. Dispersed camping is available throughout the area.
The Route
Miles 0 to 3.0: Canyon approach. The trail follows a creek drainage upstream from the trailhead, passing through stands of old-growth western red cedar and Engelmann spruce. The creek runs clear and cold. This section is heavily used by elk, and tracks in the muddy streambanks are common.
Miles 3.0 to 6.0: Climbing to the lakes. The trail steepens as the creek narrows and the drainage wall rises on both sides. Transition to subalpine fir and lodgepole pine above 5,000 feet. The first lake comes into view around mile 5.5. The main Mallard Lake is at mile 6.0 and is surrounded by rocky outcrops and subalpine meadow.
The lakes. Mallard Lake sits in a glacially scoured basin with excellent views of the surrounding Pioneer Area ridges. Brook trout and westslope cutthroat are present. The lake's outlet stream provides water for camping and day hiking (treat before drinking).
When to Hike
July and August are the prime months once the approach road opens and snow clears from the upper trail. Wildflowers bloom in the subalpine meadows in late July.
September offers elk bugling season (typically mid-September) and one of the best wildlife viewing windows of the year. The Pioneer Area is a quality backcountry hunting zone from September through October.
What to Bring
Many hikers carry 2 liters of water for the climb, supplementing from filtered creek water. Bear spray is recommended. Fishing gear is worth packing for the lake section. Layers for the summit area even in summer.
Trailhead Access
From St. Maries, head south on State Highway 3, then follow Forest Road 201 to the trailhead. The gravel road is rough in sections; high-clearance is recommended. Cell service ends at the St. Maries junction. Allow 45 minutes from St. Maries to the trailhead.
Nearby
