Gunn Peak is a prominent mountain summit rising to 6,244 feet (1,903 meters) in Snohomish County, Washington, United States. As the highest point within the Wild Sky Wilderness, it stands as a significant part of the Cascade Range, offering a rugged alpine landscape of high peaks, intricate ridges, and scenic tarns near the town of Index. Named after homesteader and miner Amos Gunn, the peak saw its first recorded ascent in 1915.
What draws experienced adventurers to Gunn Peak are the remarkable panoramic views from its summit, providing a complete 360-degree perspective of the surrounding wilderness. Hikers frequently praise the sense of achievement gained from navigating its challenging terrain, which rewards with expansive vistas of neighboring peaks like Baring, Lewis, and Merchant Peak, as well as the Sky Valley below. The unique "Infinity Tarn" near the shoulder of Tailgunner Peak also offers a stunning photographic opportunity, often featuring Baring Mountain in the background.
Before embarking on an ascent of Gunn Peak, visitors should be prepared for a demanding adventure. The route involves significant Class 3 and 4 scrambling sections, boulder fields, and potentially difficult route-finding.

Checking current trail conditions, especially regarding the impact of the Bolt Creek Fire, is also advisable.
The best time to visit Gunn Peak for climbing and scrambling is typically during the warmer, drier months when snow has receded, making the challenging terrain more accessible. This period allows for the full enjoyment of the demanding ascent and the spectacular views. While the area has been impacted by the Bolt Creek Fire, this can sometimes create unique lighting effects, adding another dimension to the scenic experience.
The journey to the summit of Gunn Peak offers several standout moments. Navigating the "catwalk" and the "hidden ramp" provides a thrilling test of skill and nerve.

It is best suited for very experienced hikers.
While specific climbing permits for Gunn Peak itself are not typically required, you will need a valid recreation pass for parking at the trailhead within the Mt.

Always check current regulations before your visit.
No, Gunn Peak is not recommended for families with young children or beginner hikers. The trail involves advanced scrambling, difficult route-finding, and exposure on narrow ledges, making it suitable only for very experienced hikers who are comfortable with challenging alpine terrain.
While dogs are generally allowed in the Wild Sky Wilderness, the Gunn Peak trail's extreme difficulty, including steep scrambling, boulder fields, and the narrow "catwalk," makes it highly unsuitable and potentially dangerous for most dogs. Consider leaving your canine companion at home for this particular ascent.
The optimal time to climb Gunn Peak is typically during the warmer, drier months, generally from late summer to early fall, when snow has receded from the higher elevations. This makes the challenging terrain more accessible and reduces risks associated with ice and snow. Always check current trail and weather conditions before planning your trip.
The time required to hike Gunn Peak can vary significantly based on an individual's experience, fitness level, and route-finding skills. Given its challenging nature, including Class 3-4 scrambling and boulder fields, hikers should plan for a full day, often 8-12 hours or more, for the round trip.
Beyond the panoramic summit views, hikers will encounter several distinctive features. The infamous "catwalk" is a narrow, exposed ledge that adds to the adventure. Near the shoulder of Tailgunner Peak, you'll find the picturesque "Infinity Tarn," a shallow pool popular for photography, often reflecting Baring Mountain. The route also includes a "hidden ramp" and extensive boulder fields.
Public transportation options directly to the Gunn Peak trailhead are extremely limited or non-existent. Access typically requires a personal vehicle. The trailhead is located in a remote area within the Mt. Baker-Snoqualmie National Forest, near the towns of Index and Skykomish.
For a challenging day hike like Gunn Peak, essential gear includes sturdy hiking boots with excellent grip, plenty of water, high-energy snacks, navigation tools (map, compass, or a downloaded route on a GPS device), a headlamp, first-aid kit, and appropriate layers for changing mountain weather. Due to the scrambling, gloves can also be beneficial.
The closest towns with limited amenities are Index and Skykomish, Washington. These small communities may offer a few basic accommodation options, cafes, or pubs. For a wider selection of services, you would need to look further afield towards larger towns in the Sky Valley or along Highway 2.
