"A New Way to Explore Napa When completed, the Napa Valley Vine Trail will be a 47-mile-long walking and cycling paththat will run the length of the valleyfrom Vallejo's Ferry Terminal to Calistoga at the foot of Mount St. Helena. For now, however, the completed sectionruns 12.5 miles mostly along Highway 29, between Kennedy Park in downtown Napa and Yountville. The bulk of this first stretch opened in 2016, and the nonprofit charged with raising money for the trail’s development had enough scratch left over to plant 300 trees that will eventually shade the walkers and cyclists, and to build rest-stop shelters and bike-repair stations along the way. Thisportionof trailrolls past a half-dozen wineries, if you’re looking to drink and ride, whiletheother nine sections are expected to open in phases through 2020."
