Overview
The White Cloud Peaks Loop is the signature backpacking route in Challis National Forest, traversing a remote alpine landscape in the Sawtooth National Recreation Area with lakes, granite summits, and expansive views. The 22-mile circuit is considered strenuous and is typically completed over 2 to 4 days.
The White Cloud Peaks themselves top out above 11,000 feet, and the loop visits several alpine lakes in glacially carved basins. This is backcountry travel at its best: remote, dramatic, and surprisingly uncrowded compared to the nearby Sawtooth Wilderness.
For bear safety in this backcountry setting, review the bear canister requirements guide before heading out.
The Route
From the Fourth of July Creek Trailhead, the loop climbs into the White Clouds via Fourth of July Creek before traversing the high basin and descending via the Big Boulder Creek drainage. The middle section visits the heart of the alpine lakes basin. The exact loop direction is a matter of preference; counterclockwise is slightly more efficient from this trailhead.
Campsites are scattered throughout the basin near established lake shores. Practice Leave No Trace camping at least 200 feet from water sources.
When to Visit
Mid-July through September. The high passes can retain snow into early July in heavy snow years. August is peak season with warm days and the best wildflower displays. September brings solitude and fall colors at lower elevations.
Practical Details
No permits required as of 2026. Bear canisters are strongly recommended. The nearest resupply is Stanley, Idaho. Cell service is unavailable throughout. Review Leave No Trace principles for backcountry camping best practices.
Getting There
From Stanley, drive south on Highway 75 approximately 12 miles to the Fourth of July Creek Road. Turn east and follow the gravel road about 6 miles to the trailhead. A high-clearance vehicle is recommended.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
Safety Considerations
The strenuous rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Challis National Forest and may be unreliable in canyon bottoms or remote terrain.
