On President’s Day (Feb. 18, 2013) admission will be FREE for everyone. (Please note that there will be a parking charge per car)    Worried about the cold? Don’t be. There are a variety of indoor attractions where guests can take a tropical vacation at Discovery Reef and Manatee Coast, say G’Day to some animals from down under at Bob & Evelyn’s Roadhouse, meet the gorillas in the African Forest, slither on over to the reptile building, and explore Asia Quest including a visit with the elephants. Many animals thrive in the cold weather including polar bears Aurora and Anana who can be seen swimming year round in pool water maintained with geothermal energy at a comfortable 40-65 degrees.   Keep in mind that the Columbus Zoo and Aquarium is open every day through February from 10 a.m. to 4 p.m. The winter months are always a great time to visit the Columbus Zoo and Aquarium, especially with 50% off regular admission this January and February.
