At a Glance

  • Remote backcountry lake with good cutthroat trout fishing
  • Solitude accessible without the extreme commitment of the Frank Church interior
  • Mixed conifer forest of Engelmann spruce and subalpine fir
  • Wildlife habitat including black bears and elk in the upper drainage
  • Views of the McCall backcountry peaks from the lake basin

Overview

Loon Lake sits in the McCall backcountry of the Payette National Forest, accessible via a 6.2-mile round trip that provides a genuine backcountry lake experience without requiring wilderness-level planning. Located east of McCall in Idaho, the trail is a favorite among McCall-area residents and resort visitors who want more than a frontcountry walk but less than a full wilderness expedition.

The lake itself is clear and cold, set in a subalpine basin surrounded by Engelmann spruce and subalpine fir. The solitude is genuine: even on peak summer weekends, Loon Lake sees a fraction of the traffic of the Payette Lake shoreline in town.

The Route

Trailhead to Lower Forest (0 to 1.5 miles)

The trail begins in mixed conifer forest and climbs moderately on a well-maintained single track. The lower forest section is pleasant and shaded, with good morning wildlife activity on weekday visits.

Mid-Climb (1.5 to 2.8 miles)

The trail steepens slightly through the mid-section as it approaches the lake basin elevation. The forest transitions from lower-elevation mixed species to the denser subalpine fir characteristic of the McCall high country. Views of the surrounding peaks begin to appear.

Loon Lake (3.1 miles)

The lake occupies a natural basin with a rocky, accessible shoreline. Multiple flat spots around the lake provide rest and fishing positions. Camping at designated spots away from the shoreline is available for overnight visitors. Return via the same route.

When to Hike

July through October is the accessible window. The trail typically clears snow by early July. The lake is at its most pleasant in August when temperatures moderate.

September and October bring fall color to the surrounding basin and significantly fewer visitors. The fishing is often excellent in September as the water cools.

What to Bring

Many hikers carry 2 liters of water for the approach, with the lake serving as a filtered source at the destination. A fishing license and light tackle are worth packing. Carry bear spray given the active black bear population in this drainage.

Trailhead Access

Loon Lake Trailhead is on Loon Lake Road east of McCall, reached via the forest road network from Highway 55. High-clearance vehicle recommended on the final miles. No fee or permit required (as of 2026). No restroom. Space for 10 to 15 vehicles.

Dogs are welcome.

Nearby
