CALISTOGA, Calif. — Reminders of ancient volcanic activity are still present all over Napa Valley. It’s partly because of that old volcanic activity that the grapes in this region grow so well, but sitting in the little town of Calistoga, that volcanic activity is still active.
You can see it at the Old Faithful Geyser just off highway 128. According to property manager Koray Sanli, it’s just one of just three “Old Faithful” Geysers in the world.
