This climb ranks #5 on the Sonoma-Napa-Lake Tri-County Top 25 list with Fiets Index of 4.65. The Ida Clayton Road climb is very scenic, with what we believe to be 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 and Traffic Report: 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.
