The sometimes paved, sometimes moderately rocky trail starts from Elk City in Idaho, winds through a vast undeveloped area, offering ATV and UTV riders peace and pristine beauty, as well as towering pines and expansive mountain views—before it ends in Darby, Montana. The corridor was named for Lloyd Magruder, a successful merchant in the 1860s who was robbed and thrown off a cliff by four outlaws – who were later rounded up, brought back to trial and hung, in 1864.
