Left Hand is fun in both directions and can be used to connect an unlimited number of rides in Boulder Valley Ranch, Boulder Reservoir, and even Heil Valley Ranch.
From the north, turn off of Neva Road through the gate just east of the parking lot. Cruise about three-quarters of a mile southwest past a shelter. Left Hand turns east after the shelter and picks up speed through a smooth section near Lefthand Reservoir. There are a couple of fun, rolling ups and downs until you reach the third bridge in a little over a mile. After the bridge grunt up a steep, but very short, climb to a gate. After the gate, Left Hand cruises due south through several more gates and a few fun features until ending at Boulder Valley Ranch parking lot.
