While the image of riding bicycles through a sun-drenched vineyard is romantic, the reality of biking in wine country can be a rigorous, athletic endeavor. But very few places offer as good a reward for your efforts. The best way to see the lay of the land on two wheels is through an organized trip—either a private tour or with a group—like those offered by Napa Valley Bike Tours. Whether it’s an afternoon jaunt or a multi-day affair, their packages have broad appeal for casual tourists and serious cyclists alike. The "Classic Napa Valley" tour begins and ends in Yountville (meaning you can bookend your day with a croissant from Bouchon Bakery and then oysters and sauvignon blanc at Bistro Jeanty) and includes fuel stops at three wineries throughout the Valley.
