Kavicsos Lake, or “pebble lake” in Hungarian, is a scenic lake about 2 km across located south of Budapest, just a 30-minute ride away from the city center. The lake sits at the site of a former pebble quarry, and hence its name. Kavicsos Lake is located within Csepel Island which is the largest island on the Danube River. The lake, including most of the island, is easily accessible from Budapest by road and the suburban railway. The lake has over five hundred houses built on numerous tiny islands in the lake. Most of these are summer homes and sheds for fishermen and anglers, but about seventy families live here year round. - (via: amusingplanet.com)
