Larch Creek

Larch Creek leaves the Billy Goat trailhead at the end of Forest Service Road 5130 and threads thirty-two miles round trip into the Pasayten Wilderness. The trail follows the creek through subalpine forest, climbs to open ridges near Nanny Goat Mountain, and intersects a network of backcountry routes that hikers can weave into multi-day traverses. Total gain runs around three thousand three hundred feet, modest for the distance — the work is in the miles, not the climbing.

The wilderness shows itself slowly. Lower stretches move through Engelmann spruce and lodgepole pine; higher segments break into wildflower meadows and stands of subalpine larch, the deciduous conifer that gives the creek its name. Mountain goats range across Nanny Goat and the surrounding ridges. Creek crossings and unmaintained side junctions demand attention; route-finding is part of the trip.

Larch Creek is a backpack, not a day hike. The first water and viable camps lie miles in. Plan two to four nights, carry a self-issued wilderness permit, and time the trip for late September or early October if the larches are the goal — the gold window is short and unforgiving of late starts.
