The ideal time to hike this trail is typically during the late spring, summer, and early fall months. During these periods, the weather is generally more favorable, offering clearer views from the summit and less challenging trail conditions. Be prepared for significant annual precipitation, which can exceed 150 inches, especially outside of peak season.
Trailhead parking is available for the Colonel Bob Trail. The primary access points are via the Colonel Bob Trail #851 and the Pete's Creek Trail #858. Always check the latest information from the U.S. Forest Service for specific directions and any current parking regulations.
The Colonel Bob Trail is located within the Colonel Bob Wilderness in the Olympic National Forest. Generally, wilderness areas managed by the U.S. Forest Service do not require specific permits for day hiking, nor are there entrance fees. However, it's always advisable to check the official Olympic National Forest website for any updated regulations or specific permit requirements for overnight stays or group sizes.
Yes, dogs are generally permitted on trails within the Colonel Bob Wilderness. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all hikers. Please remember to pack out all pet waste.
The terrain is varied and rugged, starting in a dense old-growth rainforest with roots, rocks, and debris. As you ascend, you'll encounter switchbacks, washes, and rocky sections. Overgrown vegetation is common, and some parts are deeply eroded. The last mile to the summit is particularly steep and may involve scrambling. Hikers should be prepared for muddy conditions and watch their footing due to the rocky nature.
From the summit of Colonel Bob Peak, you can expect breathtaking 360-degree panoramic views. These include Lake Quinault, the surrounding rainforest, Mount Olympus, the broader Olympic Mountains, Mount Rainier, and even the Pacific Ocean on clear days. It's often described as a truly rewarding vista after a challenging climb.
Yes, there are a couple of primary routes. The Colonel Bob Trail #851 is a direct route to the summit, while the Pete's Creek Trail #858 offers an alternative. The Pete's Creek Trail is known for a slightly less steep initial section, though it still involves significant elevation gain overall.
Yes, the route primarily follows the Colonel Bob Trail #851. Sections of the Pete's Creek Trail #858 also intersect or provide alternative access to the main trail. Additionally, the Colonel Bob Summit Trail #851.1 branches off to reach the very top of the peak.
Yes, approximately 4 miles into the trail, you'll find the Mulkey Trail Shelter. This shelter offers limited space for camping, providing a potential overnight stop for those planning a multi-day trip or seeking a break during a long day hike.
The trail passes through diverse ecosystems. In the lower elevations, you'll experience a humid rainforest with old-growth conifers like Douglas-Fir, Sitka Spruce, Western Hemlock, and Western Red Cedar, along with ferns, moss, and wildflowers. As you gain elevation, the vegetation transitions to subalpine and alpine varieties. Wildlife such as elk, grouse, and various songbirds can also be observed.
No, the Colonel Bob Trail is generally considered difficult and arduous, featuring a substantial elevation gain of over 4,200 feet to the summit. The rugged and varied terrain, including steep sections and potential scrambling, makes it unsuitable for beginners or those not accustomed to strenuous hiking.
