Big Run, Doyles River, and Frazier Trail Loop

This is a challenging and lengthy route. While komoot estimates the hiking duration at around 10 hours and 47 minutes for the full 33.5 km (20.8 mi) loop, many hikers choose to complete it as a multi-day backpacking trip due to its significant elevation changes and rugged terrain. Planning for an overnight stay is often recommended.

Expect a varied and demanding terrain. The loop features considerable elevation gains and descents, including steep downhill sections and strenuous climbs. Trails can be rocky, especially near stream systems, and you'll encounter numerous cascades and pour-overs. Some parts, like sections of the Patterson Ridge and Big Run Portal Trails, offer a true backcountry experience, meaning they are more rugged and less maintained. There are also several stream crossings, which can be challenging during high water.

The loop is rich in natural beauty and offers several notable highlights. You'll encounter beautiful waterfalls such as Jones Run Falls, Lower Doyles River Falls, and Upper Doyles River Falls, as well as the Upper Doyles Falls Overlook. The trail also passes through the Big Run Basin, the largest watershed in Shenandoah National Park, offering a remote feel. Keep an eye out for impressive vistas from overlooks like Big Run Overlook and Doyles River Overlook, especially when leaves are down.

Yes, dogs are generally allowed on trails in Shenandoah National Park, including this loop. However, they must be kept on a leash no longer than 6 feet (1.8 meters) at all times. Always pack out any waste and ensure your dog is capable of handling the strenuous and rugged terrain, including stream crossings.

Spring and fall are often considered the best times to hike this trail. In spring, you'll see wildflowers and enjoy the rushing waterfalls. Fall offers spectacular foliage. Summer can be hot and humid, with potential for thunderstorms, while winter hiking can be challenging due to ice, snow, and colder temperatures, making stream crossings more difficult. Always check current trail conditions before you go.

Check the official Shenandoah National Park website for current fee schedules and permit requirements.

A common starting point for this loop is near the Loft Mountain Wayside or the Doyles River Parking Area. Parking availability can vary, especially during peak season. Arriving early in the day is often recommended to secure a spot. Always check official park maps and resources for the most up-to-date parking information.

No, this loop is generally rated as difficult and is not recommended for beginners or families with young children. It involves significant mileage (over 33 km / 20 miles) and substantial elevation changes (over 1200m / 4000ft up), with rugged and steep sections. It's best suited for experienced hikers with good physical fitness.

While the trail follows several stream systems like Jones Run and Doyles River, and features highlights like the Doyles River Stepping Stones Crossing, it's crucial to carry sufficient water or a reliable water filter/purifier. Stream levels can fluctuate, and relying solely on untreated natural sources is not advisable. Always plan for your hydration needs, especially on a long and strenuous hike like this.

Given the trail's difficulty and length, essential gear includes sturdy hiking boots with good ankle support, plenty of water (or a filter), high-energy snacks, navigation tools (map, compass, or GPS device like komoot), rain gear, extra layers of clothing, a first-aid kit, and a headlamp or flashlight. If backpacking, you'll need full overnight gear. Trekking poles can be very helpful for the steep ascents and descents and stream crossings.
