Overview
The Queens River drains a quiet corner of the northern Boise National Forest, flowing south through mixed forest before joining larger drainages below. The loop trail that circles the upper drainage covers 10 miles with 1,500 feet of gain, a moderate circuit that delivers a genuine backcountry experience without the demanding climbs of the high-peak routes.
This is a trail for hikers who want a complete loop in genuine Idaho mountain backcountry. The Queens River drainage is less known than the Grandjean gateway routes and less photogenic than the Sawtooth lake basins, but it offers something different: a quiet, forested circuit where the pleasure is in the movement through varied terrain rather than in a single dramatic viewpoint.
The loop is well-suited for backpacking. The moderate distance, reliable water source, and available campsites make it an accessible first backpacking trip for those new to multi-day hiking in Idaho's mountains. The loop format means no shuttling and a clear sense of progress.
Understand Leave No Trace principles before camping here, particularly regarding food storage in an area with black bear activity.
The Route
Miles 0 to 3.5: River Trail
The loop begins at the Queens River Trailhead (approximately 5,700 feet) and descends gently to the river. The first 3.5 miles follow the river upstream through lodgepole pine and Douglas fir forest, staying close to the water. The gradient is minimal and the walking is easy.
The river in this section has several good fishing holes visible from the trail. Clear water runs over granite and basalt cobbles, and the surrounding forest is mature and undisturbed. Deer and elk sign are common along the river corridor.
Miles 3.5 to 6.5: Ridge Climb
At a signed junction at mile 3.5, the loop turns south and begins climbing toward the ridge that forms the loop's high point. The trail gains approximately 1,200 feet over 3 miles, a consistent but manageable climb through open forest with improving views as elevation increases.
The ridge top (approximately 7,200 feet) offers the widest views of the loop: the Queens River drainage below, the Boise Mountain terrain extending south, and glimpses of the Sawtooth peaks to the north and northeast on clear days.
Miles 6.5 to 10.0: Descent Return
The descent from the ridge follows a separate trail back toward the trailhead, moving through different terrain than the ascent. The forest character changes in this section, with more open stands and some old-growth Douglas fir on the lower slopes. The trail meets the river trail near the trailhead, completing the circuit.
When to Visit
June through October. The lower river trail is accessible from late May in most years. The ridge section clears by mid-June. Fall is excellent for the reduced crowds and fall colors in the aspen patches throughout the drainage.
What to Bring
Many hikers on this loop carry:
- 2-3 liters of water capacity; the river provides sources throughout the lower section, but the ridge has none
- A water filter
- Layers for the ridge
- Trekking poles
- A map for navigating the junction at mile 3.5
- Overnight camping gear if backpacking
Individual needs vary.
