The Crystal Springs Sno-Park is a hub for winter recreation. The trails here are open to snowmobilers, cross-country skiers and snowshoers. Some routes are groomed, while others are unmaintained.
Most of these loop trails lie south of Stampede Pass Road in the forest that lies between I-90 and the Palouse to Cascades Trail. The loops range in difficulty, so plan accordingly and bring a map (or take a picture of the one at the trailhead) to orient yourself along the way.
