Main image

Lake Ossiach (Ossiacher See) is a lake in the Austrian state of Carinthia, known locally as one of the region’s principal recreational lakes. The shoreline is punctuated by small towns and historic sites that date back to the medieval period.

The lake is a regional recreation destination with boating, swimming and shoreline trails; several villages have public beaches and boat rentals. Local festivals and concerts on the lakeside draw visitors during the summer months.

A Benedictine abbey on the lake shore dates to the medieval period and has been a notable landmark for centuries. Over time the area around the lake developed into a recreational region with tourism infrastructure concentrated in the lakeside villages.

Geographically the lake sits in southern Austria’s Carinthia region near the town of Villach and is surrounded by rolling hills and alpine peaks typical of the area.

  • Viewing and access: Best views from the north and east shores where small villages and public bathing areas provide easy access to the water.

What to See #

  • Ossiach Abbey: A Benedictine abbey founded on the lake shore in the medieval period, with surviving Romanesque and later structures that are focal points for cultural visits.

Tips for Visiting Lake Ossiach #

  • Time a visit for late afternoon or evening to enjoy the lake at sunset and to avoid the day‑time family crowds that gather at the main swimming spots in summer.
  • Use the towns of Ossiach or Steindorf as primary access points and take the Gerlitzen cable car for easy elevation and panoramic viewpoints over the lake - the cable car provides quicker, less congested access to great vistas than driving the mountain roads.
  • Set aside time to visit Ossiach Abbey and the quieter lakeside churches; these nearby historic sites are often overlooked by visitors who stick only to the shoreline beaches.
