Shadow Lake is a beautiful alpine lake with views of the Cirque of the Towers, reached via the Fremont Trail. The hike takes you through pine forests and meadows, passing other lakes along the way, with chances to spot wildlife. It’s moderately challenging due to its length, but the trail itself is not difficult. You can complete it as a long day hike or a two-day trip combined with the Cirque of the Towers loop. Late summer and early fall are the best times to visit, as the trail can be muddy or snow-covered in spring.
