The Walker Ranch Loop offers a spectacular and demanding jogging experience, winding through diverse ecosystems from open, high-altitude slopes with views of the Flatirons and Rocky Mountains to shaded evergreen forests and refreshing stretches along South Boulder Creek. You'll navigate varied terrain, including rocky sections and steep climbs, making it a true test of endurance over its 7.8 miles (12.6 km) with 1390 feet (424 metres) of elevation gain, typically taking around 1 hour and 43 minutes.
Planning your visit means preparing for a difficult route that's popular with multiple user groups, so expect to share the trail with mountain bikers and hikers. The trailhead is accessible via a scenic drive up Flagstaff Road. Given the significant elevation changes and the altitude, ensure you carry enough water and are ready for a strenuous workout, especially if you plan to tackle the challenging climbs.
This trail explores the southern half of the historic Walker Ranch, a National Historic Landmark that was once one of the region's largest cattle ranches. A notable feature is "The Wall" staircase, a section of cliff-like stone steps that adds to the trail's legendary difficulty. It's a fantastic option for experienced joggers seeking a blend of natural beauty, historical context, and a serious physical challenge.

This demanding loop takes you up two of Boulder's highest peaks, offering sweeping 360-degree views of the Colorado Front Range, the city of Boulder, and the iconic Flatirons from viewpoints like the Fern Canyon Trail ridgeline.

Planning your visit requires preparation for a strenuous workout. The route includes sections that involve scrambling over exposed ridges and very steep rock steps, particularly on the Fern Canyon Trail. While generally accessible, be ready for highly technical terrain that demands good fitness and experience. Parking is typically available at trailheads that access this popular route, but it's always wise to arrive early, especially on weekends, to secure a spot.

Tips from the Community
The trail here is nontechnical and climbs steadily along a stream up toward Bear Peak. This is a great trail to descend.

The ridgeline portion of Fern Canyon Trail offers excellent views of Boulder and the surrounding mountains, but the part of Fern Canyon Trail below treeline is not for the faint of heart. The trail is steep, rooty, rocky, and holds snow into the spring months.

The trail here gets rock and technical. The dappled from the shadows can obscure footing, so keep a sharp eye on the trail.

There is a charming stone bridge over Bear Creek that has small cascades flowing beneath it. Although power lines somewhat detract from its natural beauty, it is still a lovely spot to appreciate.

Bear Creek crosses the Mesa Trail between the Bear Canyon and Mallory Cave trails. If doing a longer hiking loop, this is a good spot to filter water so that you don't have to carry so much at the start. There are several other small streams that you will cross on the Mesa Trail, but some are seasonal and others are not strong enough to refill your bottle.

A big parking lot with restrooms and picnic tables. If this parking lot is full try the Meyers Gulch Trailhead instead – it usually has available parking.

The stream runs through a narrow, rocky valley – Rocky Mountain nature at its best. Right next to the river is a beatiful, well maintained trail.
