Cathedral Lake Trailhead | 5.6 Miles Round Trip (9.01 km) – 1,986 Feet Elevation Gain (605.33 meters)

Hikers without low clearance vehicles may need to park on Castle Creek Road, before hiking up the .5 mile dirt road to the trailhead. Most cars should make it even though there are some rough sections. Any 4wd vehicle or high clearance vehicle will have no trouble.

Hikers begin hiking along the well marked and well traveled trail through aspens. They quickly begin ascending and are rewarded with views of Castle Creek valley through aspens within the first 10 minutes of hiking. Less than 1 mile in, hikers will find a part of the trail that leads to a small viewpoint of a waterfall in the trees. Hikers continue upwards at a steady grade where gorgeous views of the creek, nearby mountains, forest, and mountains are stunning.

About 2.3 miles in, hikers will reach the junction for Electric Pass. Hikers continue straight instead of turning right towards the pass. The hike mellows out in elevation gain, crosses a creek (easy to not get wet), and meanders through bushes before reaching the lake.
