Masuria (Mazury in Polish, and Masuren in German) is a lake district in northeast Poland in the Warmian-Masurian Voivodeship. It has over three thousand lakes, the most in the Great Masurian Lakes area. Many of them are connected by channels and rivers, so it is possible to sail hundreds of kilometers from Węgorzewo to Pisz.
Regular planes from London, Krakow and Dortmund land at the Olsztyn-Mazury airport at Szymany (IATA code SZY).
Sailing and motorboating are popular sports, and a number of marinas and moorings operate in the summer.
