The southern portion of Berryessa-Knoxville Road is well paved with lots of corners but with a fair amount of traffic. Once past Pope Valley Road the northern portion soon narrows to a one lane "goat path" with poor road conditions. This portion is not for everyone. It is extremely isolated with nothing but a few rural residences scattered in the hills. It is definitely a road to "get away from it all". It will remind you of a time wrap of Northern California of the early 20th century. At the very north end the road turns into Morgan Valley Road with sweeping turns and good pavement all the way to the town of Lower Lake.
