One of Sonoma's lesser-known and oh-so-ripe attractions is its half-mile of rail-trail, part of a longer route that features vineyards and wine tasting along the way. Bring your own bike or rent from Sonoma Valley Cyclery, just off Sonoma square; they include a detailed map with directions to wineries en route. A favorite stop is Ravenswood, where the pours are plentiful and the attitude is friendly. Be sure to taste their proud new release, Icon: velvety and mmmmm-good. Pedal on to Bartholomew Park Winery, the perfect place for a summer picnic with its Frisbee-worthy lawn and big oak trees. Want to extend the pedal and go for 13 miles? No problem. Roll on to Gundlach Bundschu—at 150 years, it's the oldest family-run winery in California. And they're celebrating all summer. For an added treat, take the appointment-only Cave Tour into their immense 420-foot-long barrel cave—a refreshingly cool pause on a hot day.

TIP: Before the journey, grab a deli sandwich and other lunch treats in the enticing Cheese Factory at the northern end of Sonoma square.

Sonoma Valley Cyclery, 20093 Broadway (at Newcomb St.), Sonoma; 707-935-3377. Bike rentals start at $25 for the day. For Sonoma Valley Cyclery's handwritten map of the winery route, click here. Taste with grace. Please be responsible about wine intake while operating your two-wheeler!
