A high-fidelity visit to the London Zoo typically takes between 3 and 5 hours, depending on your interest in the various daily "Live" events and feedings. While the zoo is smaller than some sprawling suburban wildlife parks, its historic location in Regent’s Park is packed with intensive exhibits like the "Land of the Lions," "Tiger Territory," and "Penguin Beach." To see the major highlights and catch at least one or two keeper talks, 3 hours is the minimum recommended time. If you are traveling with children who want to spend time at the "Animal Adventure" play area or if you plan to have a sit-down lunch at the Terrace Restaurant, you should budget closer to a full half-day (5 hours). Because the zoo has multiple entry slots, arriving for a morning slot (10:00 AM) is the best way to see the animals at their most active before they retreat for afternoon naps, ensuring you get the full value of your ticket.
