Overview
Box Lake sits in a remote basin on the eastern fringe of the Payette National Forest, adjacent to the Frank Church-River of No Return Wilderness at the forest's eastern boundary. The 10-mile round trip through dense old-growth conifer forest is one of the least-traveled maintained hikes in the Payette, rewarding those willing to make the effort with genuine wilderness solitude in Idaho's Valley County.
The forest character of this trail is dense and deep: old-growth Engelmann spruce with massive trunks, subalpine fir with dense canopies, and a forest floor of fallen logs, ferns, and moss that absorbs sound and creates a genuinely quiet environment. Wildlife encounters are more common here than on the more popular McCall-area trails.
The Route
Trailhead Through Lower Forest (0 to 3.0 miles)
The trail enters old-growth forest immediately and maintains the enclosed atmosphere throughout the lower section. The grade is moderate and the trail follows a creek drainage with multiple water access points. The forest is dark even on sunny days due to the dense canopy.
Upper Forest Climb (3.0 to 4.5 miles)
The trail steepens in the upper section as it approaches the basin rim. The old-growth continues through this section, with some of the largest spruce visible at the upper forest edge. Trail marking becomes less frequent. Watch for cairns and tree blazes.
Box Lake Basin (5.0 miles)
The basin opens to reveal Box Lake in a rocky alpine setting. The surrounding terrain is more open than the approach forest, with views of the adjacent Frank Church Wilderness peaks. Cutthroat trout are visible in the clear shallow sections of the lake. Camping at dispersed sites away from the lake shore is available for overnight visitors.
When to Hike
July through September is the reliable window. The forest road to the trailhead is typically accessible from late June. Snow in the upper basin can persist into July.
Early season visits require careful assessment of the forest road conditions, which can be muddy and soft well into June.
What to Bring
Many hikers carry 3 liters of water for this longer route with creek filtration as backup. A paper map and compass are recommended given the less-maintained trail condition. Bear spray is standard for any remote Payette drainage. Review bear canister requirements for overnight stays.
Trailhead Access
Box Lake Trailhead is on a forest road east of McCall, requiring high-clearance vehicle for the final miles. No fee or permit required (as of 2026). No restroom. Space for 8 to 10 vehicles.
Dogs are welcome.
Nearby
Box Lake is the Payette's remote Frank Church-adjacent option. Loon Lake Trail is closer to McCall with similar lake destination character. Lake Fork Meadows Trail provides a contrasting open meadow experience. Check road conditions using the USFS guide. Practice Leave No Trace principles carefully in this fragile high-use-resistant but ecologically sensitive basin.
