Sightseeing at Lake Berryessa
On the lake:
- Glory Hole - Glory Hole is on the lake, however, cannot be approached by boat or swimmers due to the obvious danger. It is the largest morning glory spillway in the world, where during high waters, water spills into the funnel instead of over the dam. It is approximately 200 feet from the dam and narrows from 72 feet in diameter to 28 feet. The spillway exits on the south side of the dam and in dry months, the horizontal cement cylinder is a haven for skateboarders and bikers. Drive to it by taking Highway 128 to the top of Monticello dam and then pulling into the parking area on the right. Or you can hike to the Spillway Overlook on the Stebbins Cold Canyon trail.
