This climb ranks #5 on the Sonoma-Napa-Lake Tri-County Top 25 list with Fiets Index of 4.65.  The climb is very scenic, with, in our opinion, the best of Mount St Helena to be found anywhere in the North Bay.  There are also extraordinary views of hillside vineyards along the middle of the climb as well as the gorgeous Knight’s Valley to the south.

Roadway surface/Traffic:  The roadway is in poor condition which is not a problem ascending, but be cautious on the descent as there are potholes, fast approaching steep sharp turns, gravel, sun/shade spots making visibility treacherous at certain times of the day.  Traffic over the entire climb is negligible. ​

Supplies:  The nearest supplies are Jimtown Store, about 10 miles west from the beginning of the climb.
