Open-to-the-public horseback riding is hard to find in Napa Valley, but this outfitter based out of Shadybrook Estate, just east of Napa, fills the need. It offers 30- or 50-minute tours of Rapp Ranch Estate, a sprawling vineyard and parcel in the hills of Coombsville. All tours from Napa Valley Trail Rides are guided, and they're geared for visitors with no riding experience at all. Depending on the tour you book, the ride might include lunch and a wine-tasting afterward. One thing is certain: You’d be hard-pressed to find a wine tour like this one.
