Humpback Mountain

Humpback Mountain is a summit in Washington's Snoqualmie region with steep slopes leading to a rocky peak covered in boulders and talus. The terrain requires careful movement through loose rock fields that dominate the upper area.

The peak has been used by mountaineers for decades with activity records kept by the Snoqualmie Ranger District. Regional hiking interest in the area has grown gradually over time as more people discovered the mountain.

The peak draws outdoor enthusiasts who use it year-round for hiking and scrambling activities. The route appeals to people who enjoy moving through natural terrain and spending time in the mountains.

The mountain is accessed from Interstate 90 by following forest service roads to a parking area near the trailhead. Plan for changing conditions throughout the year, as snow, rain, and wet ground can affect how the route feels.

On clear days the summit offers views of several prominent peaks including Mount Rainier and Alpine Lakes. The vista across the landscape is often the highlight that makes the scramble worthwhile for many visitors.
