Winterfest and the Tunnel of Lights is celebrating its 45th year as a family holiday tradition. Halls are decked both inside and outside with over 15,000 lights. Outside, closed trolley cars transport jolly guests down a tunnel of lights for 20-30 minutes as they sing traditional Christmas carols with their trolley car operators. For an open air view of the Tunnel of Lights, one open sleigh car is lit up entirely with holiday lights. Be sure to dress warm and bring blankets! Inside, the Visitor Center is decorated like a Winter Wonderland with multiple model train layouts and lights galore.
