London Zoo: Entry Ticket

London Zoo, run by the Zoological Society of London since 1828, sits within Regent's Park and holds the distinction of being one of the oldest scientific zoos in the world. Its exhibits range from big cats and gorillas to a dedicated reptile house and children's zoo, earning a strong must-see score as a long-standing family favorite rather than a niche attraction. A three-hour visit covers the grounds at a comfortable pace, and its high walking intensity reflects the size of the site. It pairs naturally with a stroll through the rest of Regent's Park.
