KNOXVILLE, Tenn. — Zoo Knoxville is celebrating the season with a new after-hours holiday event.

Winter Nights takes place Thursday, Dec. 12 through Sunday, Dec. 15 from 5 to 8 p.m. each evening. The zoo will string up thousands of lights throughout the zoo's East Tennessee Plaza and Boyd Family Asian Trek. 

The event also features some Christmas cheer. Guests can write a letter to the North Pole and pose for photos with Santa Claus in the zoo's Christmas-tree-filled Santa's Village. 

Santa isn't the only special guest -- event organizers say Disney characters Elsa and Anna will greet fans.
