Climb Summary

This climb ranks #8 on the Tri-County Top Climb list with Fiets Index of 4.0. The first couple miles of  the climb are generally shaded under a canopy of trees.  Just past 2 miles, we encounter a  very sharp left turn and the road pitches up dramatically for most of the remaining second half of the  climb -  1.9 miles, 1,100' at 11.2% average grade.  This is a beautiful climb - the first several miles are  rural and wooded, while the steeper last half treats us to classic Napa County hillside vineyards,  quite spectacular in the spring and summer - truly some of the best vineyard-climb views  in Napa County.
