Phoenix Park
One of Europe's largest city parks, with deer roaming freely inside the city limits.
Phoenix Park is a vast enclosed parkland on the western edge of Dublin city, covering over 700 hectares — making it one of the largest walled city parks in Europe, significantly bigger than New York's Central Park or London's Hyde Park. It has been a public green space since 1747, though its origins go back to the 1660s when the Duke of Ormonde enclosed the land as a deer park for Charles II. Today it sits right in the middle of a living city, and yet feels genuinely wild in places — a remarkable thing for a capital.
The park is home to a herd of around 600 fallow deer that roam freely and have done for centuries. You can walk or cycle for hours and still feel like you haven't covered it — past the Papal Cross (erected for John Paul II's 1979 visit, when over a million people gathered here), the Wellington Monument (the tallest obelisk in the British Isles), the Victorian walled kitchen garden at Ashtown, and the Dublin Zoo, which sits within the park's boundaries. The American Ambassador's residence and Áras an Uachtaráin, the official home of the Irish President, are both inside the park too. The Visitor Centre at Ashtown Castle is worth a stop for context.
The park is open 24 hours and entry is free — always has been, which feels like a gift from the city. Go early on a weekday morning if you want the deer-sighting experience without crowds; they tend to congregate around the Fifteen Acres area, the large open plain in the centre-west of the park. Cyclists can pick up bikes at the park gates. If you're arriving by public transport, the 37 bus from the city centre stops near the main Parkgate Street entrance.
