Old Faithful Geyser of California Tours and Activities

Old Faithful Geyser of California, in Napa Valley, is one of the most visited places in the American West. This isn’t Old Faithful, that’s in Yellowstone Park. But, this geyser erupts roughly every 10 to 45 minutes, sometimes more frequently. It has its own museum dedicated to geology, an animal farm and petting zoo, and bocce courts.
