The best zoos, farms and other animal attractions in London
"Richmond Park, a national nature reserve, comes up trumps thanks to its population of 630 red and fallow deer roaming free. Come here anytime of the year for peaceful deer spotting, but for a more spectacular site, plan a visit during breeding season (Autumn) and watch as the red stags and fallow bucks compete for females by roaring, barking and clashing antlers. Make note, this is a park not a zoo, so take precaution and keep at least 50 metres from the herds."
