Hyde Park is pet-friendly. One of London’s finest historic landscapes covering 142 hectares (350 acres), the largest of four Royal parks across the city is a must-visit for pups. There is something for everyone in Hyde Park. With over 4,000 trees, a lake, a meadow, horse rides and more it is easy to forget you’re in the middle of London. Please note that dogs are not allowed in the Princess of Wales Memorial Fountain, Lido swimming area, Serpentine Lake, or Bowling Green and Tennis centre area, and that dogs must be leashed in the Rose Garden and at the edge of Serpentine Lake.
