The hike to the Loch, also known as the Loch Vale, is just under six miles round trip and is as beautiful in the winter as it is during the summer. The hike begins at the Glacier Gorge trailhead in Rocky Mountain National Park and takes you past Alberta Falls and a dramatic gorge before reaching the alpine lake. The Loch can get quite windy, so be sure you have enough winter gear with you (and gloves that allow you to take photos!). The trail, rated as moderate on Alltrails.com, gains 1,072 feet of elevation, but overachievers can tack on a few extra miles by visiting Mills Lake (follow signs at the junction about two miles from the trailhead).
