 Sonoma County Top 5 Scenic Bike Climbs

This is the climbing backbone of what many feel is the jewel of Sonoma County cycling, King Ridge Road.  The ranking is misleading low because there are so many rollers over the 16 miles course - the primary climb is 3.8 miles at 6.1%, but the full accepted King Ridge route from Cazadero  is 16.5 miles gaining 2,614’ while descenting 1,674’.  

Climb begins in the small (pop. 420) west county town of Cazadero.

Climb start

First 16 miles of the remote roadway is predominantly bordered by trees.

PJAMM Cycling riders on King Ridge Road

The "ride" is really 16 miles of rollers from the start to the junction of King Ridge/Hauser Bridge Rd/Tin Barn Rd (16 mile route map), which consists mostly of steep pitches followed by descents.  We are exposed to the best of Sonoma County cycling along this route - challenging climbs, remote venue, grazing cattle, vineyards, minimal traffic, and distant views of mountains and ridges to the east and west.  

This is cattle country . . .

King Ridge Road - manure on roadway 

. . . we mean it!!

There very few residences . . . .

. . . but a lot of ranch structures on this ride.

Climb by bike King Ridge Road - vineyards and lake 

Some vineyards along the way - it is Sonoma County, after all.

We also ride through some redwood stands along the way.

King Ridge Road is the centerpiece of Levi's Gran Fondo (circa 2003), an extremely popular and well run wine country century held in September each year and attended by 7,500 riders, give or take.

There is a very pleasant loop that exposes us to all that Sonoma County has to offer which runs from Cazadero-King Ridge-Hauser Bridge-Seaview-Timber Cove-Hwy 1-Fort Ross Road (Map and displayed at the bottom of this page).

Supplies:  This is remote cycling - there are minimal spots for supplies along this ride and the loop noted above.  There are supplies at the Cazadero General Store near the start but nothing after that (except water at the Ratna Ling Retreat Center at mile 19.5) .  You can also begin at Raymond's Bakery one mile south of Cazadero to fuel up and grab a deli sandwich at the Caz General Store at the end of the ride - you can't go wrong with that plan as part of your itinerary!

Roadway surface/Traffic:  The roadway is in moderately poor condition, but manageable by all - just a bit bumpy along the way at spots.  Traffic is next to nothing - very remote with a true private feel to it.
