It’s hard to go half-a-mile in Napa Valley without passing a vineyard or winery — not that we’re complaining — but there is one beautiful and uncharted destination that’s worth a day trip during your California Wine Country vacation. Lake Berryessa is 26 miles long, but just 3 miles wide, with a myriad of quiet coves and 165 miles of shoreline to explore by car, bike, boat, or foot. In the summer, the water temps reach up to 75 degrees, making it the ideal destination for camping and boating with friends.
It even has a glory hole; a spillway at the Monticello Dam. A decade-long dry spell ended in 2017 following heavy rains and turned this little-known glory hole into a tourist destination for a few wet weeks.
