On the south end of Sonoma is one of the most unique appellations, Los Carneros, that bridges both Napa and Sonoma counties. Carneros has long been known for its cool, coastal climate, natural beauty and unparalleled Pinot Noirs, Chardonnays, Syrahs and sparkling wines. Just a short distance away is the quaint, historic riverfront town of Petaluma with its antique shops, boutiques, restaurants and historic architecture.
