The Peterson Ridge Trails were initially constructed in 1989 as a mountain bike trail network of interconnected trails and forest roads. An expansion in 2008 increased the single track to over 20 miles and included signage and trail markers. Depending on your desired distance and difficulty, you can create your loop or choose a shorter out-and-back route.

The trails are generally considered easy to moderate. They’re mostly flat, with rolling hills and occasional rocks and roots. This makes them perfect for runners of all abilities, from beginners to those looking for a relaxed run with scenic views.

 

The single-track trails are friendly to all types of runners.

 

There are plenty of options within the Peterson Ridge network. You can easily create a loop of 2-3 miles using the connector trails or create longer loops of 10 miles or more by utilizing the entire trail network.
The Peterson Ridge Trails offer stunning views of the Cascade Mountains, including the Three Sisters peaks. Depending on the season, you’ll also likely encounter wildflowers and diverse wildlife.

Be aware that Peterson Ridge is a multi-use trail system. You will encounter mountain bikers, hikers, and dog walkers. Several horse trails interconnect into this system. Be courteous and practice trail etiquette to ensure a safe and enjoyable experience.

Sisters Trails Alliance maintains the Peterson Ridge Trails. Before heading out for the run, it is best to take a picture of the trail map showing all the numbered junctions and trail names to guide the run.

An 18-mile loop with just over 1000′ of ascent that combines the West and East trails starts at the Peterson Ridge Trailhead on Three Creeks Road just south of Village Green Park. This clockwise route uses trails from Peterson Ridge Rumble, Sisters Country, Oregon Cascades 100, and Three Sisters Skyline trail races.

Start on the East trail and continue past the marked trail junctions. After 1.75 miles, there is a junction that can be used to return to the West trail for a short run. Stay left for another half mile to the Eagle Rock Pass junction. This is another way to loop back to the West trail using the challenging but beautiful Eagle Rock Pass.

Stay left to continue on the loop. In about another half-mile, the trail crosses the FR-4616. Continue staying left at the trail junctions until Three Creeks Lake Road. This is the highest point in the loop. Restrooms are at this spot, and it is an excellent point to get extra nutrition to complete the second half of the run.

Continue on the right (east) side of Three Creeks Road for just under a mile and turn right away from the road. Continue staying left for about six more miles to cross over Forest Road 1605 again. Stay left for the last one and a half miles to the trailhead to complete the loop.
