Out and back: ride north on Puetz Valley Rd. 1 mile to single track trail head. Trail climbs steadily for about 4 miles and connects with rutted fire road that drops in from Alpine. For loop: ride the paved Alpine Blvd. 5-6 miles to and through the town of Alpine to East Victoria Rd. Turn north (left) onto East Victoria (steep uphill) to Anderson Rd.
