Overview
Harrison Lake Loop is a satisfying moderate circuit in Coeur d'Alene National Forest, combining lake views, forest hiking, and a high point with mountain panoramas. The 6.4-mile loop gains 1,200 feet and is well-suited to hikers looking for a full day hike that's challenging enough to feel rewarding but not overwhelming.
The lake is the centerpiece, and the loop allows hikers to view it from multiple angles as the trail circles through the surrounding forest and ascends briefly to a viewpoint on the east ridge before descending to complete the circuit.
For a shorter lake option, the Moose Lake Trail is nearby.
The Route
From the trailhead, the loop begins counterclockwise along the west shore of Harrison Lake, then climbs to the east ridge for the best panoramic views. The ridge section offers the only significant elevation gain on the route. The descent back to the trailhead follows the east and south shores of the lake through dense forest.
When to Visit
June through October. The loop is accessible before higher-elevation Coeur d'Alene forest trails clear of snow. Fall color in the surrounding forest is excellent in October.
Practical Details
No facilities at the trailhead. Dispersed camping is permitted. Water from the lake requires treatment. Review Leave No Trace principles.
Getting There
From Coeur d'Alene, drive east and north on forest roads into the Coeur d'Alene National Forest interior. Contact the Coeur d'Alene Ranger District for current trailhead directions and road conditions.
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 moderate 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 Coeur d'Alene National Forest and may be unreliable in canyon bottoms or remote terrain.
