California 175
Routing
California 175 connects U.S. 101 in Hopland with California 29 in Lakeport, then turns southeast to Middletown via Cobb Mountain. From Lakeport through Kelseyville, the route is a multi-lane divided expressway. The route over Cobb Mountain and the Hopland Grade are both winding roads. Over Hopland, the highway hugs the landscape as it wends it way over the grade, while the route through Cobb Mountain and Whispering Pines has reduced visibility due to the forested areas it traverses.
