Lake Berryessa

Visit napa county's largest lake

At over 23 miles long, Lake Berryessa is a must-see marvel. One of the largest freshwater lakes in California, this scenic natural wonder is bordered by miles of trails, roadways, and hills jutting out from the valley. Visit Monticello Dam which plunges hundreds of feet below the reservoir and catch a glimpse of the bell-shaped Glory Hole spillway that many have mistaken for a mysterious natural phenomenon.
