The historic trail provides grand views across the Town of Mammoth Lakes into the Long Valley Caldera and can be traveled in either direction: up or down. From a staging area of Sherwin Creek Road the narrow single-track climbs gently, cutting spectacularly along the steep contour of the Sherwin Range, rising above Snowcreek Meadow, crossing beneath a prominent outcropping of limestone and marble known as Mammoth Rock and ending at its junction with upper Old Mammoth Road.
