One reason to visit the Brevard Zoo, of course, is the animals. There are particularly interesting assortments of giraffes and exotic birds that are very friendly and allowed to get very close to visitors. But it's even more fun to supplement your visit with the Treetop Trek, which as the name suggests allows you to to get a monkey's eye view of the animal habitats while traveling through the trees on zip lines, rope bridges and other challenges. Five course options are available, offering various levels of difficulty. One includes a 700 foot zip line that has you flying over wetlands and alligators.
If you go:
Closed on Thanksgiving and Christmas, but otherwise open every day. Hours are 9:30 to 5:00 except for days of special events, when closing time is at 3:00. The Treetop Trek operates from 9:00 to 5:00, but the last tour of the day must leave early enough to be finished by closing time. Note that separate admission is charged for the zoo and Treetop Trek, and you need not do both.
