Among the smaller British collections, it's a real gem. Just enough big animals (lions, leopards, rhinos, wolves) to feel like a 'proper' zoo but a wonderful mowed-lawn-and-Cotswold-stone-walls setting and fantastic collection of smaller animals - including the lemurs (sifaka, mouse lemurs, two species of gentle lemur among them), White-lipped Peccaries (and now Warty Pigs), Ground Cuscus, Striped Possum, Purple-faced Langurs, Morelet's Crocodiles, Bredl's Python, an aviary with three cuckoo species (Guira, Greater Roadrunner and White-browed Coucal), the African Openbills, Hildebrandt's Starlings...
Yeah - worth a trip!
