Stone Tree Ranch is a polo and equestrian ranch nestled in the hills of Calistoga of northern Napa Valley.

We founded this ranch out of our passion for the sport of polo and our love of horses. We offer professional polo one-on-one lessons, training, grooming and full service polo patron packages including training, horse lease and transportation so that all you need to do is show up to The Trione Field or Polo Club in “the desert” and play.
