Fun! The bikes were very nice, helmet fit and just the right amount of time biking for me. If you are a serious biker, this may not be for you. Got to the keep the bikes after and we went for a short ride further and stopped for lunch. The winery we visited was nice and friendly, didn't push you to purchase. Richard, out guide, was attentive to the needs of one or two individuals who were leery of biking. All in all, definitely worth it and our foursome agreed it was one of the more fun things we did on our trip to Napa.
