Napa Valley is known for its wine and vineyards. With over 300 wineries, it's responsible for over 25 percent of the wine consumed in the U.S. The vineyards have evolved into a major tourist attraction as well, and there are many ways to see the area.

One of the best ways to both see and taste the area is the Napa Valley Wine Train. It's a three-hour, 36-mile round-trip that takes visitors from the town of Napa, through the Napa Wine Valley to the village of St. Helena and back.

Passengers are served a freshly prepared lunch or dinner inside a fully restored 1915-1917 Pullman Dining Car or a 1952 Vista Dome car as they enjoy the scenery of the vineyards as the train passes them. Passengers can also purchase a winery tour for a more up-close view of the vineyards and wine making process.

The route passes through the towns of Napa, Yountville, Oakville, Rutherford and St. Helena, also passing numerous wineries.

In addition to the stops, there is also a murder mystery to be solved on board, as well as lectures about the areas various vintners. The different activities that take place on board vary throughout the year.
