Ok thanks It looks brilliant, thinking of visiting instead of Berlin zoo? My main thing I want to see is predators so bears, cats and dog species so is this better for that?
Well, if you're a zoofan and have the time, you should try visiting both the Zoo and the Tierpark. There are many rarities both places. There is some overlap in species, but also plenty only kept in one of them. Unless willing to miss a lot, don't plan on visiting both in a single day; they're big (Berlin Zoo is more than twice as large as London Zoo, and the Tierpark is much larger than Berlin Zoo). If I absolutely had to pick one, it would be the Zoo. There are more species of bears in the Zoo than in the Tierpark, and more cats in the Tierpark than the Zoo, but it should be mentioned that the Alfred-Brehm cat house and the sun bear enclosure IMO are the two weakest points in the entire Tierpark (updates to these enclosures are on the way/planned).
