I've done Mt. Healy from Bison Gulch and even Antler Creek a few times. But I wanted to try it the longer way from the Denali National Park Visitor Center. This route follows the Mt. Healy Overlook Trail and then continues on up the ridge until the summit. The only thing to really remember is to follow the ridgeline once the trail begins to disappear. It is steep and but incredible from this route!
