Visit Hertfordshire for rambling country estates, orderly garden towns and cathedral cities. Picnic outside revival mansions with forest backdrops, redbrick Jacobean manors with mazes and gothic courts encrusted with gargoyles. Span centuries in St Albans' Roman amphitheatres and Norman cathedrals. You can come face to face with dragons and ghouls straight from the Harry Potter films and get close to endangered snow leopards at exciting wildlife parks. This home county hasn't forgotten its shopaholics either, with outlet malls and new towns aplenty. Top places to visit in Hertfordshire include St Albans Cathedral, the Warner Bros. Studio Tour London, Cassiobury Park and the De Havilland Aircraft Museum.
