"Boo at the Zoo," held each Halloween, is a highlight for this zoo. Get there early so you don't miss out--I have seen the line wrap around the whole complex. The kids (and adults) come dressed in costume and "trick or treat" their way around the zoo. They always leave with a bag full of candy. In addition, there are face painting, crafts, costume and jack-o-lantern contests, and more.
Visit Idaho Falls Zoo for all of the special days as well as other useful information.
Open daily May through September, plus weekends in October, November, and April.
