Sharing a name with the famous blowhole in Yellowstone National Park, the Old Faithful Geyser of California offers a highly predictable natural spectacle. Make your way to the lovely Napa Valley town of Calistoga, arriving at any time during the park’s operating hours to use your general admission ticket. Enjoy the serene surroundings as you wait for the exciting moment when the geyser erupts.
Roughly every 30 minutes, watch a pressurized spray of water shoot up from the middle of a pond, reaching heights of 60 to 100 feet (18 to 30 meters). The impressive display is entirely natural and comes from a river that runs through molten lava deep underground and is forced up through a hole in the earth’s surface.
Feel free to watch the spectacle as many times as you like, or wander around the grounds. Visit the on-site geology museum to learn more about geysers, and take a peaceful stroll through the native plant gardens. Enjoy a game of bocce ball, and be sure to say hello to the resident farm critters including a guard llama, four-horn sheep and a small herd of Tennessee fainting goats.
