It’s Festival Time, friends! Our holiday extravaganza is in full swing with crafts & gift vendors, chainsaw artists, glassblowing classes, food trucks & specialty bars in our Makers Market heated tents. Come see the Mack Glass team build the masterpiece tree out of 6,000 recycled & melting bottles. Get the two-weekend-only schedule and purchase your $5 entry tickets (new this year) on the World’s Tallest Glass Tree website by clicking the link here. Yerkes’ Great Refractor Dome micro-tours during the festival must be reserved on our website by clicking Tickets.

Please note, all vehicles MUST park at Williams Bay School in the Geneva Street lot. Trolleys run back & forth shuttles (only a five-minute ride) during the festival. Vehicles absolutely can not drive through Yerkes’ driveway. Our gate will be staffed and closed during festival times & will be locked during non-festival times. Can’t wait to see everyone around the campfires & glass tree!
