Wild Sun Winery is located at 4830 Pioneer Rd, Hillsboro, Jefferson County, Missouri. We had been looking for some place new to try and we rather enjoyed the outdoor seating at this winery on May 21, 2016. Some time after we arrived, the place started filling up with people and I could tell that as with many wineries closer to St. Louis, it is hard to avoid the crowds. We like the more crowdless places where you can find bits of peace. It was not far from the Sandy Creek Covered Bridge which is just north of the winery.
