Climbing Etna Summit northwards on is a seriously steep but rewarding ascent into the remote Klamath Mountains. Prepare for a tough climb of approximately 7-8 miles while gaining around 3,000ft to reach the ~6,070ft summit where the Pacific Crest Trail crosses. You'll face a significant challenge: the average gradient is a demanding 8.2%, with the second half being particularly relentless, featuring sustained double-digit grades, including a mile averaging 12% and ramps hitting 15% or more. You'll be climbing through quiet, beautiful forests, with views opening up near the summit.

Climbing towards Mount Shasta via the Everett Memorial Highway is a long, steady ascent offering increasingly dramatic, close-up views of this iconic volcano. Prepare for a sustained climb averaging a consistent 5.6-5.8% over approximately 11.5 miles to reach the Bunny Flat Trailhead area near 7,900ft which will see you gaining nearly 4,000ft from near town. The journey to the top of this Fourteener sees you climb through forests opening up to spectacular mountain vistas on generally good surfaces with light traffic.

Though it might pale in comparison to Mount Shasta's grandeur, Black Butte is still a prominent landmark in southern Siskiyou County and it definitely captivates drivers with its conical shape as they approach it on Interstate 5. Hiking it to the top will allow you to get acquainted with its particular surface formed from viscous lava and it will also unveil the well-kept secret of its lush northern valley.

Faint but detectable trail from the North Gate trailhead to the foot of Hotlum/Bolam ridge. The route continues up the ridge, though it's not marked and even less visible, and seasonally partly snow covered into late spring in the upper reaches. Once on it the ridge is quite straightforward to follow.

This is the complete trail from the Trailhead to the Clear Creek springs. After registering at the trailhead and paying the fee for climbing over 10'000 feet elevation the trail climbs gradually through pine forest along the canyon rim to the source of the creek. The best, and only, source of water along the entire trail. From there several more faint tracks climb steeply to the summit.

Siskiyou County is dominated by Mount Shasta, an impressive 14,179-foot stratovolcano and the second-highest peak in the Cascade Range. Other significant peaks include Mount Eddy, the highest point in the Klamath Mountains, and Black Butte Summit, a distinct volcanic landmark. The region also features peaks within the Marble Mountain and Russian Wildernesses, such as Boulder Peak and Russian Peak.
The difficulty varies significantly. Mount Shasta, for instance, is a strenuous endeavor, often requiring technical skills, especially when snow-covered. Routes like Avalanche Gulch are considered challenging. Mount Eddy offers a moderate ascent for experienced hikers, providing a great introduction to peak bagging. Other peaks within wilderness areas can range from moderate to challenging depending on the specific trail.
Late spring to early fall (roughly May to October) is generally the best time for mountain hiking in Siskiyou County. During this period, snow has typically melted from lower and mid-elevation trails, and the weather is more stable. Summiting higher peaks like Mount Shasta is often undertaken in late spring when snow cover can make traversing easier, but rockfall danger increases without snow in late summer/fall.
While many prominent peaks offer challenging climbs, there are easier options or trails around their bases. For instance, the hike to Deadfall Lakes on Mount Eddy's flanks is a highlight with moderate sections. The area around Schonchin Butte & fire lookout offers an intermediate trail with great views. For truly easy options, consider trails around Lake Siskiyou or the lower sections of trails leading to peaks, which often provide scenic views without significant elevation gain.
From Siskiyou County peaks, you can expect spectacular vistas. Mount Eddy offers panoramic views of Mount Shasta, Black Butte, the Trinity Alps, and Mount Lassen. The Whaleback provides great views of Mount Shasta, Shastina, and Mount McLoughlin. Many peaks feature diverse ecosystems, including lush alpine meadows, glacier-carved lakes, and dense coniferous forests. Volcanic origins are evident in peaks like Black Butte Summit and Schonchin Butte & fire lookout.
Yes, while some peaks are challenging, there are family-friendly options. Trails around the base of Mount Shasta, such as those leading to Castle Lake and Heart Lake, offer picturesque views and are suitable for families. The McCloud Falls area, with its three distinct waterfalls, is another popular hiking destination that can be enjoyed by families. Always check specific trail conditions and difficulty before heading out.
Dog policies vary by specific trail and wilderness area. Generally, dogs are permitted on many national forest trails, but often require leashes. However, some designated wilderness areas or specific trails might have restrictions. It's always best to check with the local land management agency (e.g., U.S. Forest Service) for the most current regulations regarding dogs on the specific trail you plan to visit.
For challenging hikes, consider the Mount Shasta via Avalanche Gulch Route or the China Gulch Trail to Grizzly Lake. For moderate options, the Cliff Lake via Shackleford Trail is a good choice. Many trails, including sections of the Pacific Crest Trail, offer access to various peaks and scenic areas. You can find more hiking options in the Hiking in Siskiyou County guide.
Mount Eddy, at 9,026 feet, offers a significantly less strenuous and technical ascent compared to Mount Shasta (14,179 feet). While Mount Shasta requires significant mountaineering experience, often involving snow travel and glacier awareness, Mount Eddy's easiest route from the north (via the Pacific Crest Trail or Deadfall Meadow) is considered moderate for experienced hikers, making it a more accessible peak for those looking for panoramic views without extreme technical challenges.
Yes, Siskiyou County offers winter activities. The Mt. Shasta Ski Park provides opportunities for skiing, snowboarding, and snow tubing. Many trails, such as Faery Falls and Heart Lake, are popular for snowshoeing in winter. Bunny Flat is the closest accessible point by car to Mount Shasta in winter, serving as a popular starting point for snowshoeing and ski touring. Always be prepared for cold weather, deep snow, and potential avalanche hazards during winter excursions.
Beyond hiking, Siskiyou County offers a variety of outdoor activities. You can find numerous running trails, including the challenging Pacific Crest Trail: Siskiyou Peak to Big Red Mountain. Road cycling is also popular, with routes like the Lake Siskiyou – Mumbo Summit loop. The region's lakes and rivers provide opportunities for water sports, and the diverse landscapes are excellent for nature photography and wildlife viewing.
