Mount Spokane State Park's Trail 131 is accessible year-round, but receives its highest use in the winter as a main snowshoe access trail. Beginning at the junction of Mount Spokane State Park Drive and the Summit Road (gated in winter; typically open early June through late September or early October), the main parking area is on the east side of Mount Spokane State Park Drive. This area is a winter SnoPark lot, and in the summer a Discover Pass is required.
Begin the hike up trail 131 by crossing Mount Spokane State Park Drive and hiking up past the green trail kiosk which marks the beginning of the trail. The trail initially skirts the Park maintenance and groomer shop, then climbs through a thick forest. At approximately 0.25 miles the trail intersects an old roadbed and turns right. It continues a few hundred feet to where trail 131 makes a sharp left turn toward Bald Knob Picnic Area. The old road continues straight/right and becomes trail 132, a summer-only trail as it intersects the alpine ski area where hiking is not permitted during the winter.
From the junction of trail 131 and 132, the trail continues climbing through a forest of subalpine fir, hemlock, western larch, lodgepole pine, and an occasional western white pine as it climbs toward Bald Knob Picnic Area and campground. Summer users can continue trail 130 as it exits Bald Knob (to the CCC cabin and beyond, as trail 130 encircles the entire summit of Mount Spokane, eventually connecting back to trail 132). Snowshoe users can also choose to follow trail 130 as far as where it intersects with the alpine ski area concession, or may choose to follow the winter-only snowshoe summit route to the top of Mount Spokane.
