Big South Fork Bike Trails
The Big South Fork has over 450 miles of trails and about 300 miles are open to mountain biking. The National Park Service uses trail markers to designate trail uses. With a few exceptions, the trails open to mountain bikes have difficulty ratings ranging from beginner to intermediate. Several trails are specifically signed for bikes. Many of the multiple-use trails and wagon routes also offer good mountain biking in all but very wet weather conditions. Some of the other trails open to both horses and mountain bikes can be a challenge for bikers except during very dry or very cold (i.e., when the ground is frozen) conditions.
Several of the most popular trails for mountain biking are described at the links below. See the IMBA-associated MTB Project webpage for a more complete list of Big South Fork trails open to mountain biking. The MTB Project webpage includes scalable maps and elevation profiles for the listed trails.
Popular trails accessible from the Bandy Creek Visitor Center include the Collier RIdge Loop, West Bandy Creek, Duncan Hollow, Grand Gap Loop, and John Muir Trails. Or combine them to ride the IMBA-designated Big South Fork Epic.
The Rock Creek, a more northern setment of the John Muir Trail ending at the John Muir Overlook, and the Chestnut Ridge Trails accessible from Divide Road in the northwest corner of the Big South Fork.
