How late into the year is the zoo open?

Cassdace the zoo open year round except for on Tuesday's. The little boo which is for kids 5 and under and pumpkin patch for 5&up. Those are the weekend of Oct 15th an 16th from 10-3. If you want the kids to trick or treat there is a charge of I believe $7 each child. The lights before Christmas is Nov 29th-Dec 31 starts at 5:30. I hope this helps you out

Once we hit LBC season, the week before Thanksgiving (LBC opens Nov. 19th) the Zoo will open at 3 pm for LBC. Right now it looks like Jan buildings will be closed and no concessions but if you want to come and walk around the zoo and see outdoor stuff you can. I'm not sure of hours at moment.

Year round

Yes I do believe that they are open year around

Past October bc they have the Halloween event there and then I believe in November is the Xmas lights event so I believe they close in Nov.
