You are allowed to walk around the zoo before our ceremony and after until it closes at 5pm. The Wilder Institute Calgary Zoo is a non-profit educational Zoo, they provide excellent enrichment for their animals and top-notch care. We went to Zoolights on our first date and have been back to the zoo many times since. We especially love going to see the Penguins, Otters and the Red Pandas so make sure you have a look around!
