Route Description for Harmonica Arch Trail

You will not regret hiking the Harmonica Arch Trail. This stunning path impresses 100% of its adventurers. Note that self-issued permits are required and can be found at the trailhead. This path, though trafficked, is one of a kind. Gradually climbing in the initial segments of the hike, the rearmost ascent to arch is challenging. Be prepared to scramble up the steep, technical terrain to the overlook. Pack plenty of water and wear layers as insurance against windy conditions at the exposed arch.

Begin your journey to Harmonica Arch from the Goose Creek Trailhead. From the trailhead, track along the path and veer right at the first intersection. Cross Goose Creek and trek along the path as it guides you below tree shade. Travel along the babbling creek and you will pass several dispersed campsites. Hike along the trail and you will eventually have to divert from the marked Goose Creek Trail up to Harmonica Arch. Though trail markers are sparse, you will be able to notice the frequented path in the northwest. Use the trail GPS to help you navigate the primitive path.

Continue hiking along Goose Creek until you reach the forested gulch. Climb up the steep, rocky valley, following the cairns. Mind your footing as you scramble up the rocky terrain to an unforgettable overlook of the surrounding verdant and mountainous landscape that are the backdrop to the Harmonica Arch. Revel in the anomaly that is the granite arch and explore the rock summit. When you are ready, retrace your steps back to the parking lot.
