The only walk thru section is in the middle where the gift shop and cafe are. Basically just a petting zoo. There is an overlook into the top of the hillside maned wolf enclosures, but I have not actually seen a maned wolf there. Some of the breeding areas (eg prairie chicken) are off exhibit. The only time I have personally seen an attwaters prairie chicken was on a recent visit to the excellent Caldwell Zoo in Tyler.
