Napa Valley - Tourist Attractions / Parks

Tidy vineyards range in rows across the rolling hills of Napa Valley, a destination known for its fine wine production.  Though only roughly nine percent of the land in this valley is dedicated to grape growing, the region supports several hundred wineries making this a tourist tasting hot spot.  It's not all Pinot Noir and tasting parties in these parts though - between varietals consider a detour out to see some of the area's cultural sights and parks.
