You can view the off-exhibit hoofstock yards immediately after getting off of the skyfari at the top of the zoo. If you want to get a decent glimpse from afar, I suggest bringing a good zoom lens.
@Zt2fan94@pachyderm pro You can also walk up there if you don't want to take the skyfari, just keep following the sidewalk that goes past the cougars and then the mara/anteater. You can get a fairly decent view with your own eyes, but binoculars are a less heavy option than a lens
