Most of the major attraction animals (cougars, tigers, wolves) are accessible via paved paths, and staff was friendly and helpful. They opened gates that had been closed for Covid to give me an easier path. I wasn’t the only person there in a wheelchair that day either! On the other hand, getting down to the birds in particular involved some steep hills and gravel paths that were pretty hard to navigate. Unless you can walk short distances or wheel rougher terrain, you’re going to have to miss out on the birds.
