Embark on the Cole Loop and Gray Butte Trail for a challenging hike through the Crooked River National Grassland. This difficult route covers 11.5 miles (18.5 km), ascending 2077 feet (633 metres) over an estimated 5 hours and 40 minutes. You will experience varied terrain, from technical and rocky sections to smooth singletrack, with the High Desert landscape unfolding dramatically from the Gray Butte Summit.
When planning your visit, be aware that the trail can become very muddy and difficult to traverse during wet conditions due to the area's 'gumbo' clay. Hikers have also reported icy conditions in winter, making some sections unsafe without proper traction. It is always best to check current trail conditions before heading out, and consider turning back if you encounter significant mud or ice. Proper footwear and gear are essential for this demanding outing.
This trail offers a unique perspective on the High Desert, especially during spring when vibrant wildflowers like arrowhead balsamroot and lupine add color and fragrance to your journey. The significant elevation changes and diverse surfaces contribute to a rewarding experience for those seeking a substantial and memorable day on the trails.

You can typically find parking at the Gray Butte Trailhead. This trailhead provides direct access to both the Gray Butte Trail (#852) and the Cole Loop Trail (#854), which form the core of this route.
Yes, dogs are generally welcome on the trail. However, as it's located within the Crooked River National Grassland, it's always best to keep your dog on a leash to protect wildlife and ensure a pleasant experience for all trail users, including equestrians and mountain bikers.
The spring is often considered the best time to visit. During this season, the High Desert landscape comes alive with vibrant wildflowers like arrowhead balsamroot and lupine. However, be prepared for potential 'gumbo' (slippery, clay-like mud) if there has been recent rain. Winter can bring icy conditions, making some sections unsafe without proper traction.
Generally, there are no specific permits or entrance fees required for day hiking on trails like this within the Crooked River National Grassland. However, it's always a good idea to check the official USDA Forest Service website for any current regulations or alerts before your visit.
The terrain is quite varied and can be challenging. You'll encounter technical and rocky sections, as well as smoother, buffed-out singletrack. Be prepared for significant elevation changes, especially on the ascent to Gray Butte Summit. During wet periods, the trail can become very muddy due to a slippery, clay-like soil known as 'gumbo,' which can make hiking difficult.
Absolutely! The trail offers glorious and unique views of the High Desert. From higher points, you'll get distinctive perspectives of the surrounding landscape. The Gray Butte Summit is a key highlight, providing expansive vistas. In spring, the trail itself becomes a landmark with abundant wildflowers.
Given its 'difficult' grading, significant distance (over 18 km), and considerable elevation gain, this trail is generally not recommended for beginners or families with young children. The technical and rocky terrain, combined with potential for muddy conditions, requires a good level of fitness and experience. There are likely more family-friendly options in the wider Central Oregon area.
Yes, the route utilizes and connects several trails. The majority of the route follows the Cole Loop Trail No. 854 and the Gray Butte Trail. You'll also traverse sections of Forest Road 57, Forest Road 5720, and Forest Road 5700-100. It's even possible to connect to trails leading towards Smith Rock State Park for a longer outing.
This trail is popular with hikers, mountain bikers, and equestrians. The Cole Loop Trail No. 854, in particular, has historically seen significant equestrian use. Always be mindful of other users, especially on blind corners, and yield appropriately to horses and uphill traffic.
The best insider tip for avoiding the notoriously slippery 'gumbo' mud is to check recent trail conditions and avoid hiking after significant rainfall or during prolonged wet periods. If you encounter muddy sections, it's often advised to turn back rather than risk slipping or damaging the trail. Prioritizing dry conditions will ensure a much more enjoyable and safer experience.
The trail is located in a more remote area near the Crooked River National Grassland. For amenities like cafes, pubs, or accommodation, you would need to travel to nearby towns such as Terrebonne, Prineville, or Redmond. It's best to plan for these services before or after your hike, as they are not directly at the trailhead.
