4.3 miles. 2058 feet elevation gain. Cold Springs Trail connects the Cascade Lake Day Use Area with Mount Constitution Rd. and is the trail most often used for training by prospective mountaineers. The trail climbs up the west side of the mountain with numerous switchbacks, creeks, and vistas looking out towards East Sound. Start at the trailhead on top of the mountain beside a picnic shelter and head down for an easier route, or commence your hike from the Day Use Area for a rigorous journey that locals use to prep for hiking in the Cascade Mountain Range. This hike can take a few hours going up or down, and several flat promontories are great for snack breaks and picnics. Hikers can travel from the trailhead across Mt. Constitution Rd. to the Little Summit/Mount Constitution trail for further mountaintop adventures. Biking is permitted during the offseason.
