The elevation for Hadley Peak is at 7415. The route to Hadley Peak is through The Skyline Divide trail which is a 6000-foot-high ridgeline extension of Mount Baker. The Skyline Divide trail is 4.5 miles long before there is a 3 mile section that is a mix of boot pack path that runs the ridgeline over some of the most beautiful and magnificent terrain. As you approach the summit, there is a lot of loose rock and scree below the peak which makes the summit approach very difficult. At the peak there are views of Mount Baker and Mount Shuksan which are incredible. Total distance from trailhead to summit is 7.4 miles.
