This route was planned by komoot.
The full round-trip hike to Buckhorn Mountain is a demanding journey. Komoot estimates the duration to be around 7 hours and 34 minutes of moving time. However, given its 'difficult' rating and significant elevation gain, many hikers plan for a full day, often 8-10 hours, to account for breaks, enjoying the views, and the challenging terrain.
The trail offers a diverse and challenging terrain. It begins by winding through a lush old-growth forest alongside the Big Quilcene River. As you ascend, the landscape transitions to open alpine meadows with abundant wildflowers. The final push to the Buckhorn Mountain summit is particularly steep, rough, and open, often described as a tough climb on loose rock and scree, similar in difficulty to Mailbox Peak. Hiking poles are highly recommended for stability.
The trail typically starts from the Big Quilcene Trailhead, located within the Olympic National Forest. Parking is available at the trailhead. It's advisable to arrive early, especially on weekends, as this is a popular and challenging route.
Yes, a Northwest Forest Pass or an equivalent federal recreation pass is generally required to park at the Big Quilcene Trailhead, as it is located within the Olympic National Forest. You can find more information on passes and regulations on the USDA Forest Service website. There are no additional entrance fees specifically for the Buckhorn Wilderness itself, but standard wilderness regulations apply.
The best time to hike this trail is typically from late spring through early fall (June to September). During this period, the snow has usually melted from the higher elevations, and the alpine meadows are vibrant with wildflowers. Late spring and summer offer the most favorable weather conditions and the best chance to experience the trail's full beauty.
Yes, dogs are generally allowed on the Big Quilcene Trail within the Buckhorn Wilderness, which is part of the Olympic National Forest. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all hikers. Always practice Leave No Trace principles, including packing out all pet waste.
The trail is rich with natural beauty and stunning vistas. You'll pass through old-growth forests and alongside the Big Quilcene River. A major highlight is reaching Marmot Pass, which offers extensive views and is a popular destination itself. From the Buckhorn Mountain summit, you'll be rewarded with unparalleled 360-degree panoramic views of the Olympic Mountains, the Cascade Range, Puget Sound, and the San Juan Islands.
The trail is known for its abundant wildflowers, especially in the upper sections and around Marmot Pass during late spring and summer. Keep an eye out for mountain goats, which are commonly sighted in the higher elevations, though it's crucial to maintain a respectful distance. The lower sections also offer opportunities to spot various forest birds and small mammals.
Yes, there are designated camps along the way, such as Shelter Rock Camp and Camp Mystery. Marmot Pass is also a popular spot for overnight stays, offering incredible stargazing opportunities. When camping, always follow Leave No Trace principles and avoid sensitive alpine meadows to minimize your impact.
Yes, the route primarily follows the Big Quilcene Trail #833 for a significant portion. It also briefly intersects with sections of the Pacific Northwest Trail 03 Washington, the Buckhorn Mountain Summit Trail, and the Tubal Cain Trail, offering potential connections to other wilderness adventures.
No, this trail is consistently described as 'difficult' and 'very strenuous' due to its length (approximately 12.6 miles round-trip) and significant elevation gain (around 4,400 feet). The final ascent to Buckhorn Mountain is particularly challenging. It is not recommended for beginners or families with young children; it's best suited for experienced hikers with good physical conditioning.
