Discover the dog-friendly Olmstead Loop Trail in El Dorado County, offering scenic views of rolling hills, oak trees and wildflowers in spring. At 8.6 miles and rated easy to moderate, the trail’s terrain is suited for most hikers and is open to mountain bikers and equestrians as well. Side trails on the canyon offer panoramic views of the North Fork American River and the Auburn Dam construction site.

The loop works well if you want to break up the distance — you don’t have to commit to the full 8.6 miles. Trail markers have been posted about every half-mile and at most trail intersections, which helps you navigate if you decide to bail out early or explore some of the spurs. The elevation gains are manageable, and the mixed terrain of dirt and rocky sections keeps things interesting without being punishing on your dog’s paws.

There is a strictly enforced leash law for dogs on the trail, so plan accordingly. The trail can get busy on weekends, especially when the wildflower display peaks in spring, so an early morning or weekday visit tends to be more peaceful. You’ll likely encounter other hikers, mountain bikers, and horse riders, so keeping your dog close and under control makes the experience better for everyone.

The trailhead and parking are located behind the fire station in Cool. To get there, take Highway 49 south to Cool and turn right just before the fire station and blinking red light. This is also the staging area for equestrians, so you might see riders gearing up when you arrive. The trailhead is on the south end of the parking area. There are no facilities at the trailhead itself, so bring water for both you and your dog before heading out.
