Housed in a big redwood barn, Mumm is a fun place to stop for a glass (or bottle) of bubbly and a stroll past its exceptional photography exhibits. Just beyond the extensive gift shop (filled with all sorts of namesake mementos) is the tasting room, where you can purchase sparkling wine by the glass ($7-$15), three-wine flights ($12-$25), or the bottle ($20-$85). You can also take a 45-minute free educational tour -- with your dog because this joint is pooch friendly! -- and stroll through the impressive fine-art photography gallery, which features a permanent Ansel Adams collection and ever-changing photography exhibits. Sorry, there's no food or picnicking here.
