An unusual salt lake formed from an old branch of the Danube, Lake Szelid can be found 4 km southeast from Dunapataj. The lake, with a maximum width of 200 m and length of 4 km is only three meters deep on average. Thus warms quickly in the summer, sometimes reaching 28 degrees Celsius. Apart from the therapeutic effects of the medicinal salts, the lake is also used for relaxation and fishing. There is a campsite nearby and a sandy beach on the southern side.
