Oberösterreich is as famous for its string of beautiful lakes as it is for its thermal springs of drinking water. Set on the border with Bavaria (Germany), South Bohemia (Czech Republic) as well as Lower Austria, you can take your pick from bathing lakes, from glorious Lake Mondsee, which is known as the warmest reaching 26C (79F) in summer, to vast Lake Hallstatt, with one of the largest fish populations in the region. The beautiful mountain scenery here creates a wonderful setting, with the chance to combine walking and cycling routes along with a whole host of watersports beyond diving. With steep face-dives, thrilling rock formations and tangled roots sheltering a whole variety of sea life, some lakes are crystal clear, others are darkened by plankton and yet others feature car wrecks and even an old phone box. You can take your pick of a host of different dive entry points at various lakes and explore the amazing mix of sites in Oberösterreich.
