On 08.08.1809 the Tyrolean and Sextner Landsturm were able to stop twenty-fold superior French and Italian forces. Today's ruins testify to these events and is considered particularly worth seeing. The most important sacral building is the medieval parish church in the main village. A popular hiking destination and yet an insider's tip is the beautiful Reiterkirchl on the Reiteralm, built in 1849. It provides a wonderful view onto the varied mountains of the Lienz Dolomites on the other side, which regularly "glow" in Leisach’s sunset.
Warm summer days can be spent in a quiet and idyllic atmosphere in the Leisach’s Waldschwimmbad (public swimming pool in the woods). Moreover, several popular excursion destinations, such as the challenging Goggsteig and the family-friendly climbing paradise Galitzenklamm, are in direct proximity to Leisach. Especially the Galitzenklamm is a real insider tip in Osttirol! A via ferrata specially arranged for families, a versatile climbing world, a waterfall observation circuit with water playground and a snack station promise a varied daytrip or holiday. In Leisach you can also join the popular Drau Cycle Path, which leads further downstream towards Lienz and Upper Carinthia. In neighbouring Lienz, skiers can carve down the slopes on two boards in the ski areas of the Lienz Bergbahnen (mountain railways).
