Calpine offers free tours to the actual sites of its "closed-to-the-public" geothermal plants and wells, but you need to sign up well in advance for a place on this popular attraction. The facilities are scattered up in the Mayacamas Mountains and are connected by a network of roads and pipes that are reached from the Visitor Center by comfortable charter... More

I enjoyed the interactive displays, and some of the earthquake simulators were great! I enjoyed some of the student displays. Good experience for the whole family!

I didn't even know the name of this company, and CalPine generates more electricity than any other independent power producer in... More

This was an alternative to (or diversion from) the wineries, and part of an enjoyable day trip from Calistoga. There is gr8 information on the deveolpement, but not a lot of bling. I had no idea of the huge amount of alternative energy that is being produced in the area at the largest geothermal complex in the world. The history... More

There were a few exhibits and the building was new.The woman in the office never acknowledged us or asked us if we needed help. No one else was there. It looks more like a place for... More
