We went to Sonoma county for a few days, and saw the tour on trip advisor. The guide Nicky was very nice and made sure everyone was comfortable at all points on the ride. Even when we encountered a rattlesnake, she was calm and collected and made sure we waited for the snake to go a safe distance away before proceeding. We kept it to a walking pace for pretty much all the ride, my horse would trot to catch up a few times. It was a nice mellow afternoon ride. I would highly suggest taking their advice to wear jeans.
