Come to the Petrified Forest to step back in time, over 3 million years, and follow the trail of majestic petrified redwood giants arrayed before you in a fascinating grove in beautiful California wine country.
Take a walk with family and friends and be a witness to redwood trees that once grew in abundance here and were turned to stone 3.4 million years ago by a local volcano. What has been described as one of the finest examples in the world of an ancient forest is preserved here at the Petrified Forest, in Calistoga, California. This unique site at the gateway to the Napa Valley was created following a violent volcanic explosion 3.4 million years ago. Seven miles northeast of this property lies the remains of an extinct volcano that today we call Mt. St. Helena.
