This January, get rewarded for recycling! Bring any outdated phone book to the zoo for recycling and get a great deal on zoo admission, thanks to the annual partnership between YP® and Knoxville Zoo.

Now through Jan. 31, 2014, visitors can present an outdated phone book for recycling at the zoo's ticket window and receive one free admission ticket with the purchase of a regular paid admission ticket. Since the zoo is currently celebrating Penguin Discount Days, when admission is half-price, this means visitors who bring an outdated phone book can get two admission tickets to Knoxville Zoo for $10.

A January visit to Knoxville Zoo is one of the area's best-kept secrets; many of the animals, such as the red pandas, otters and big cats, enjoy the crisp weather and are more active during the winter months. The zoo also has plenty of indoor viewing areas for animals such as chimpanzees, gorillas, elephants and penguins on days when it is too cool for them to be outdoors, as well as the perfect indoor place to play, Wee Play Zoo.

The annual recycling program is part of Knoxville Zoo's and YP® 's commitment to recycling and conservation. Special thanks to event sponsor YP® . This promotion is not valid with any other coupon, discount or offer and ends Jan. 31, 2014.
