Letná is a hill overlooking Prague historic centre and Vltava River just besides Prague Castle. It neighbors the Stromovka (the largest park in Prague) and Letná parks. The hill belongs to Holešovice and Bubeneč quarters of Prague 7. The main part of Letná is Letná Plain (Letenská pláň), a large empty plain and Letná Park (Letenské sady) popular for summer strolls and informal sports (inline skating and jogging being the most popular here).
