Two options to continue when coming down from the CalPark tunnel bike trail or from the Larkspur ferry: Either take the wooden boardwalk to follow the north bank of the creek inland to the bridge there or to Kentfield, or cross the creek here via the narrow concrete sidewalk on the highway exit bridge east side.
