About This Trail

From the Bubbles Divide Trailhead, chase North Bubble on a 1.5-mile out-and-back that climbs about 400 feet. Expect rocky, exposed sections; a loop combining both peaks can push the outing to 2-3 hours. This hike is moderate—steady footing, water, and caution on ledges. High reward for the effort.
