The Lake Marian track is a moderate 6.1 kilometer or 3.8 miles return hike, leading to a breathtaking alpine lake nestled in a hanging valley and reflecting the surrounding peaks. The trail is a steady climb to the lake with 400 meters or 1312 feet of elevation gain. The footing is rough, with lots of tree roots, which can become very slippery when wet. On a warm summer day, the lake itself is a popular place to swim and hang out, so make sure to bring your swimsuit!
