Winter Wonderland featuring Light Up Williston. It's a night of fun for the entire family that will include games, snacks, drinks, crafts, children’s amusements and a foam party — all FREE! The only money you will spend will be if you choose to buy dinner from one of our food trucks. Everything else -- everything -- is FREE! And Santa and Mrs. Claus will be there to hear Christmas wish lists. Williston Wonderland is FREE because it’s paid for by the Chamber and our partners who believe in our community.
