Attersee

The Attersee is about twenty kilometres long and covers some forty-six square kilometres, which makes it the largest lake entirely within Austria, lying north to south in the Salzkammergut with the Höllengebirge along its eastern side. The water is exceptionally clear - visibility of twenty metres or more is normal - which has made it the main freshwater diving lake in the country, with dive sites along the steep western shore. Gustav Klimt spent fifteen summers here from 1900 and painted most of his landscapes on and around it, a good number of them square-format views of the water and the shore; a small Klimt centre at Kammer and a marked path cover the sites. Sailing is heavy, the wind is reliable, and prehistoric pile dwellings on the lake bed are part of a UNESCO inscription.

What you actually see

• Austria's largest inland lake - twenty kilometres of very clear water.
• Freshwater diving - visibility over twenty metres along the western shore.
• Klimt's landscape ground - fifteen summers of painting, marked by a trail.
• Reliable sailing wind - the reason the lake is thick with boats.

When to go

May to September. A day.

Honest expectations

The water is clear because it is cold - swimming is bracing all summer. Shore access is broken up by private property in places. Summer weekends fill the villages and lakeside parking.
