Climb Summary


Cycling Sonoma County - Trinity Road - pjamm cyclist at finish - fire station

Volunteer Firehouse is the finish of the Trinity West climb.

Trinity West ranks #12 on the Tri-County Top 25 list, with Fiets Index of 3.67. This is a favorite climb for local cyclists and is one of the few connectors between Napa and Sonoma Counties.  The views are not spectacular, but the climb is challenging and generally a steady 6-10% from start to finish.   The finish of this climb is at the intersection of Cavedale and Trinity Roads at the Mayacamas Volunteer Fire Station, where there is normally water and a cycling pump -- it is "cyclist friendly" (Thank you MVFD!).
