Yountville Pope Valley Loop
This route takes you into the Vaca Mountain Range to the east of Napa Valley. The main ascent is via Howell Mountain Road which is one of the more popular climbs for cyclists, perhaps due to the scarcity of automobile traffic. You will enjoy many panoramic views as you continue into Pope Valley. Here the route turns to the south and takes you through the valley farms before descending back into Napa Valley.
