Hike Through the California Petrified Forest

California’s Petrified Forest is the Calistoga Petrified Forest, and it’s truly one of a kind. Visit this unique forest near Napa Valley to travel back in time. Here you can see petrified trees that were turned to stone millions of years ago when a volcano erupted.


Mount Saint Helena is a mountain in the Mayacamas Mountains region, and was originally a volcano. Millions of years ago, it erupted, releasing heavy ash into the air. This ash settled on the trees and in the water, causing the trees to fossilize over thousands of years.

3.4 million years later, in 1870, Charles Evans was working on his farm. He discovered what looked like a log made out of stone. This lead to the discovery of other trees, and eventually to the oldest petrified forest in California.

California’s Petrified Forest has the largest petrified trees in the world. One tree named “The Queen” measures 8 feet wide and 65 feet long. Can you imagine standing next to that?
