"Ascend to panoramic views of the surrounding mountains."
Bonanza Peak is the tallest non-volcanic mountain in Washington State, rising to an elevation of 9,511 feet (2,899 meters). It stands proudly in the Glacier Peak Wilderness within the North Cascades. Known for its rugged terrain, striking views, and challenging ascent, Bonanza Peak is a favorite among experienced climbers and serious adventurers. Unlike many of the well-known Cascade peaks, Bonanza remains relatively remote and untouched, making it an ideal destination for those seeking solitude and natural beauty.
Getting to Bonanza Peak is part of the adventure, as it involves multiple modes of transportation. The most popular approach starts from the town of Lucerne, which is accessible only by boat or floatplane from Chelan, Washington. You’ll need to take a ferry operated by the Lake Chelan Boat Company to reach Lucerne. From there, you’ll ride a bus up to Holden Village, a remote community that serves as the gateway to the mountain.
From Holden, it’s a long and demanding hike on established trails like the Holden Lake Trail or the Company Creek Trail. Bonanza Peak’s summit requires technical climbing skills, including glacier travel, rock scrambling, and route finding. This is not a casual hiking destination—it is best suited for mountaineers with experience in remote alpine terrain.
The weather around Bonanza Peak is typical of the North Cascades—unpredictable and subject to rapid changes. Summer months (July through early September) offer the most stable conditions, with daytime temperatures ranging between 50°F and 70°F (10°C to 21°C) and cooler nights that can dip below freezing.
Snow can linger on the mountain well into July, and sudden storms may bring rain or snow even during the warmer months. Always check the forecast and prepare for alpine weather, including strong winds and low visibility. Fall and winter conditions are extremely harsh, with deep snow and avalanche danger, making climbing very risky outside the summer window.
The best time to visit Bonanza Peak is from late July to early September. During this period, trails are more accessible, snow has melted significantly, and weather conditions are relatively more predictable. Earlier in the season, climbers may encounter snowfields, especially near the summit, requiring crampons and ice axes.
Visiting outside of this summer window is not recommended unless you are a highly experienced mountaineer equipped with winter gear and avalanche knowledge. The remoteness and difficulty of the approach mean that rescues are extremely challenging.
Bonanza Peak is best known for being the highest non-volcanic mountain in Washington State. It is also among the most challenging peaks to climb in the North Cascades due to its rugged terrain, remote location, and lack of marked trails. Its dramatic alpine setting includes glaciers, steep rock faces, and panoramic views that rival any in the Pacific Northwest.
Unlike more crowded destinations like Mount Rainier or Mount Baker, Bonanza offers an unmatched wilderness experience. It is often included in lists of Washington’s toughest and most rewarding climbs, drawing those who seek adventure and solitude.
There are no entry fees to access Bonanza Peak or the surrounding Glacier Peak Wilderness. However, if you plan to park at a nearby trailhead or forest area on your way to Lucerne or Holden Village, a Northwest Forest Pass may be required.
Visitors traveling through Holden Village may need to notify the community in advance, as it is a private Lutheran retreat center. They welcome respectful hikers but appreciate advance notice. Camping is allowed in the wilderness areas surrounding the peak, and hikers should practice Leave No Trace principles.
There are no services near Bonanza Peak. All gear, food, and emergency supplies must be carried in. Cell service is non-existent, so it's wise to carry a satellite communicator or GPS device.
Bonanza Peak was first climbed in 1937 by a team of climbers from the Cascade Alpine Club. Its name is believed to have come from nearby mining operations, particularly the Bonanza and Crown Point mines, which were active during the early 20th century.
Geologically, the peak is made up of metamorphic rock, shaped by ancient tectonic activity and glaciation. The mountain features several glaciers, including the Mary Green Glacier, which is commonly used as a route to the summit. The presence of these glaciers adds to both the beauty and challenge of the climb.
