The trail covers 0.5 miles, making it an ideal option for hikers seeking a quick outing or those with limited time. The relatively short distance and out-and-back format provide straightforward navigation, with hikers simply retracing their path on the return journey. This trail offers access to Harlequin Lake, a destination worth the brief walk. The National Park Service maintains the trail as part of its recreational offerings in the Wyoming area.
