Park in the lower parking area (follow the entrance road farther West) for easy access to this trail. Horseshoe Lake is also accessible from the Ridge Trail (see above), so you could begin your hike of the Ridge Trail from this parking lot or walk South from the other parking lot, to reach this.
Follow the well marked packed dirt path to the lake, crossing a bridge along the way. There is a loop around the lake, but the tail end of it is not as stroller or wheelchair friendly as the beginning.
