Cycling Geysers Road - Sonoma County’s second hardest road bike climb
Ride 4.1 miles gaining 1,841’ at 8.7% average grade.
Climb summary by PJAMM’s John Johnson.
This is the fourth highest Fiets Index ranked climb in the Sonoma-Napa-Lake area and offers spectacular views of the Alexander Valley, one of the premier vineyard regions in the world. The climb, with a couple of exceptions, has a fairly even, albeit steep, 6-8% grade throughout. The descent of the Geysers is one of the most exciting in the county. During the summer, the temperatures can approach and exceed 100 degrees, so beware of the weather.
Supplies: Geyserville and/or the Jimtown Store have any supplies you would need for this climb.
If climbing Ida Clayton, Geysers or Pine Flat, be sure to stop at the Jimtown Store
6706 Hwy 128, Healdsburg
Roadway surface/Traffic: The roadway is in fairly good condition, other than 2 brief stretches of gravel just beyond the 3 mile mark. Traffic is very light and the road is wide and often has a bike lane. This is one of the safer climbs you will find.
