Because the heavy motorized traffic tends to be even heavier in the summer, we recommend that you ride this route in the spring or autumn. If riding in summer is your only option, be advised that motorized traffic often increases after 10:00 a.m. You'll encounter climbs several miles in length as the route crosses two major headlands between Crescent City and McKinleyville. This is redwood country, so take some extra time to enjoy the scenery in the state and national parks along the route. At Leggett you'll leave US 101 and return to the coast via SR 1, but not before climbing abruptly to 2,000 feet above sea level. From either direction this roads is a steep, twisting climb and descent on a narrow roadway that is hemmed in by heavy forest cover. From Westport to Bodega Bay SR 1 hugs the coastline, passing through small towns that cater to tourists. In Marin County, the traffic increases on the route from Valley Ford to Marshall, especially on weekends after 11 a.m. Between Fairfax and the Golden Gate Bridge you'll be riding in an urban environment. The route follows a signed bike route along residential streets and bike paths wherever possible.
