Zoo Lights will span through 70 acres of Denver Zoo's campus, with nightly entertainment, animal encounters, Santa meet-and-greets and, of course, illuminated animal sculptures that swing through trees, jump across lawns hide in bushes and appear in places where they’re least expected. One of Denver’s most anticipated events, which is a great opportunity for folks of all ages to enjoy the holidays or kick off the New Year with family, friends and colleagues. Daytime admission (including membership) does not include Zoo Lights. Denver Zoo will close at 5 p.m. (gates close at 4 p.m.) and reopen at 5:30 p.m. for Zoo Lights. Pre-Sale available and the event is extremely popular.
