Winterfest is the official "kick off" to the riding season here at Brimstone.It is a group ride lead by our local trail masters. Riders from all over the country gather here looking for good trails, good times, and good fellowship with other riders. On an average, around 1,000 riders take part in it. Winterfest is our official way of saying hello to Spring and goodbye to Winter. It is a highly anticipated time!
