Join Free: singlesbythebaytravel.com For our local members we do some awesome hikes throughout Northern California. This hike was in Calistoga in the heart of wine country. Located in Napa County, Calistoga is home to some awesome hiking trails just a short drive away from many vineyards. After this hike we went on a tour of an amazing replica Tuscan war castle winery called Castello di Amorosa. The wine is fantastic and the setting is like nowhere else in the world.
