The trail climbs 5 miles northward to the summit. The mountain is suitable for hiking, snowshoeing, and even mountain biking. The summit provides a good take off for para-gliding and hang-gliding. Camping on the mountain is not highly recommended due to the winds that are nearly constant in Skagway and the large presence of brown and black bears.
