"Discover the Natural Side of Napa Situated on the east side of the Mayacamas Mountains between Calistoga and St. Helena, the 1,900-acre Bothe–Napa Valley State Park offers something that’s otherwise hard to find in the valley: open space. The park featuresmiles of hiking and walking trails to explore, but the most popular thoroughfare is the Redwood Trail, which winds 1.5miles along the ridgeline ofRitchey Canyon and brings hikers face-to-face with tiny ferns and towering Douglas firs along the way. The park also boasts a picnic ground that’s open year round; it’s a great spot to eat sandwiches and samplea bottle of cabernet or pinot noir from one of the nearby tasting rooms. In summer, Bothe–Napa Valley opens a spring-fed swimming pool shaded by mature trees. Also, don't miss the "Native American Plant Garden, Wappo People" trail, next to the Visitors Center, which displays some of the plants still used today for ceremonies, food, medicine, and basket-weaving."
