TREE TIME!!!  >>> Tickets MUST be reserved on our website. No walk-up sales, please. ALL PARKING (except the 4-pack ticket) is at Williams Bay School, three minutes from Yerkes. Go into the 500 W. Geneva St. lot and turn left. Shuttles will run continuous back-and-forths. The gate at Yerkes will be closed and/or staffed all December. You cannot drive through. The legendary tree construction is meant to be seen as it’s being built by the artists and community. It’s meant to be experienced spinning, lighted, and with music at this winter extravaganza featuring Magpie’s food truck, hot drink huts, beer & wine, chainsaw artists, torch & furnace classes, and HEATED tents full of regional gift & artist shops. New this year: All tickets allow entrance inside the Observatory for Yerkes gift shop and a walk up to see the world’s biggest lens telescope in the Big Dome. Yes! It’s a grand ol’ time!
