Autumn's crisp air and bright colors inspire travelers to embrace the outdoors. Cooler weather makes it an ideal time to take a hike or road trip to admire the fall foliage. Fall is also harvest season, so the best places to vacation include wine-country regions from California to Virginia. In many places, it's easy to combine leaf-peeping with stops at farmers' markets and apple orchards, plus seasonal treats like cider donuts or pumpkin pie. For families, autumn's corn mazes, hayrides, and roster of kid-friendly festivals are added incentives to keep traveling after school in back in session.
