Bothe-Napa State Park, Napa, CA. Babbling streams will be your soundtrack as you challenge yourself on the lush singletrack within Bothe-Napa Valley State Park. The course is a bit challenging with the hills, streams and rocks – which makes it all the more exciting and rewarding. This state park is a local treasure that is untapped by tourists and located just minutes from the area’s great restaurants and wineries.
