Besides free-roaming llamas, Llama Trek also features guinea pigs and rheas, both native to South America. Guinea pigs will be roaming in an exhibit modeled after Peru’s Machu Picchu. Rheas, which are large flightless birds, will have their own space next to Llama Trek. Llama Trek is open through Labor Day and is free with general Zoo admission. While at Llama Trek, guests can purchase a ticket to walk a llama on a special llama path!
