Zoo Lights is returning to Denver Zoo for its 31st year, and this season's celebration will be extra special —  it's also the Zoo's 125th anniversary.

"Zoo Lights, presented by Your Front Range Toyota Stores, is back as the final toast in a year-long celebration of Denver Zoo's 125th anniversary," said Jake Kubié, Director of Communications at Denver Zoo, in a press release. "For the 31st year, the Zoo will transform into Colorado's wildest holiday tradition with more than 2 million LED lights sparkling over 80 acres, along with a new crop of light installations and offerings."

On top of enjoying the new light installations, guests can also see the Zoo's nocturnal animals in the Tropical Discovery and El Pomar Village Hall exhibits. Animal enthusiasts can even purchase a Giraffe Feeding.
