This 37 acre hillside park was established by naturalist Robert Jackson in 1963. Today, the Zoological Society of Wales has taken the helm and operates the zoo more like conservation lands for native wildlife within. Guests are treated to wooded acres, tree lined paths, and rolling hills teeming with grey heron, grass snakes, and badgers. The must-see exhibits are the modern Eurasian Otter showcase—outfitted with a river, and waterfall for happy otters to slide and frolic about—and that of the California Sea Lions and the Humboldt Penguin.
