Trail guide
Copper Lake Trail is a short out-and-back from the shared Twin Lakes Trailhead to a small forested lake. Count about 0.9 mile (1.4 km) round trip and allow about 30 minutes of walking, plus time at the shore. The route is gentle and mostly level; go for an easy lake visit, not a summit hike or a big overlook.
Cross the long wooden bridge over the creek. At the T-junction, turn left for Copper Lake; the right branch is the separate Smith Lake route. The Copper path is a single track through evergreen forest, with moss underfoot and few rocks or roots. It slopes gently toward the lake. Look through the trees for Eisenhower Peak; highway traffic can carry through the more open stretches.
The trail ends at clear, shallow water, where submerged boulders and fallen trunks show through near shore. Forested slopes and a mountain backdrop make a pleasant short stop, though this is a modest lakeside finish rather than a sweeping viewpoint.
The shared lot has no toilets or drinking water, so fill up before you arrive. Dogs are allowed on leash. Parks Canada does not list this spur separately in its hiking information, so check current trail restrictions before setting out.
