Bike climb Cavedale Road - cyclist riding past roadway monument

Interesting monument near the start.

Private funds contributed in 1915 to build the road.

Sheesh . . . talk about inflation!

The view along much of the first half of the ride is very scenic, with  spectacular views of the Sonoma Valley and its vineyards far below.  The grade is  generally smooth (albeit moderately steep), with a few extreme pitches (a couple of short stretches in  the 16% range).  

Narrow road, but minimal traffic and some great views of the Sonoma Valley

This likely put the “Cave” in Cavedale!

Descent:  We stongly recommend against descending this road.  The pavement is extremely poor, with many potholes, gravel and  rough stretches (one of the worst in Sonoma County).  The alternate descent is Trinity Road which intersects Cavedale about 2.3 miles west along rolling generally flat terrain.
