Napa Valley's next door neighbour offers the same breathtaking vistas of the rolling countryside and delicious California wines, but with a slower-paced, more relaxed vibe (and more affordable price point). Skip the big name hotels and opt for a romantic boutique lodge or bed-and-breakfast (like the Tuscan-inspired Kenwood Inn & Spa) to relax between visiting the vineyards. And if you're not too afraid of heights, the best views of the valley are by air — hot air balloon, that is!
