Construction Updates

Stay informed about the latest construction updates on the Napa Valley Vine Trail!


 

Coming Soon! | Napa Valley Vine Trail | Calistoga to St Helena

From the Calistoga Depot to Pratt Avenue in St. Helena, this picturesque 8.2-mile stretch of the Napa Valley Vine Trail will guide you through Napa Valley's finest vineyards and the majestic oaks of Bothe-Napa Valley State Park, steeped in rich local history. 

During the construction phase, please demonstrate respect and mindfulness to our workers and farms. Although tempting, please DO NOT use the trail until the opening this fall.

If you're eager for more adventure, take a short ride south to Yountville. There, you'll find the 12-mile VINE TRAIL segment that connects Yountville to Napa.

Looking ahead, the Napa Valley Vine Trail will start construction on 7.5 miles in Vallejo this fall.

Lace up your shoes or hop on your bike, and let the adventure begin!
