A 5.4 mile out-and-back hike that passes numerous waterfalls and cascades. The trail begins by following North St. Vrain Creek to Copeland Falls, a series of falls dropping 12ft. Later, the trail crosses the creek and climbs to Calypso Cascades, a 90ft series of cascades streaming down the mountain fed by Cony Creek. After crossing the cascades on a series of bridges, the trail climbs another mile to Ouzel Falls, a 60ft waterfall fed by Ouzel Creek. Turn around here for the 5.4mi hike or continue on to Ouzel or Bluebird Lakes if you desire a longer trek.
