California’s Napa County is well known for its wine industry and beautiful scenery. Between its lush green rolling hills and wildflower covered valleys, it easily ranks among one of the most naturally picturesque places in America.
There is so much to see and explore throughout the area and when the timing is right, one of the main attractions can be found at Lake Berryessa.
The seventh largest man-made lake in California is held back by the 304 foot tall Monticello Dam and is home to the famous “Glory Hole” spillway.

Sitting just yards away from the concrete lip of the dam, the spillway is funnel shaped just like how a morning glory flower is, hence the name.

At the opening and widest point, it measures 72 feet across before narrowing down to approximately 28 feet as it drops straight down two-hundred vertical feet! Once it reaches the bottom it bends ninety degrees and then straightens out before eventually draining out on the other side of the dam into Putah Creek.
