Founded in 1828 by the Zoological Society of London (ZSL), London Zoo pioneered the scientific zoo model—prioritizing research, conservation, and education over spectacle. Today, it houses ~14,000 animals across 380 species in Regent's Park.
~1.2M annual visitors (pre-COVID). 60% UK residents, 40% international. Peak: summer weekends, school holidays. Quietest: weekday mornings November-March.
Tickets: £27-33 adult (online discount). ZSL membership = unlimited entry + Whipsnade Zoo (Bedfordshire, 600 acres). Tube: Camden Town (Northern) or Regent's Park (Bakerloo). 15-min walk.
Elephant exhibit closed (2001) — welfare concerns. Polar bears phased out. Current master plan: larger habitats, fewer species, more in situ conservation storytelling. The zoo that invented the scientific zoo is reinventing it.
