Take Tram D to Nusstodorf. Walk up across the hill to Kahlenberg through lanes fringed by vineyards and wine gardens, where people go in the autumn to drink the new wine. Once you enter the Vienna Woods, you will see violets, aconites and celandine among the trees if you go in the spring. It was at Kahlenberg that the Polish king John Sobieski said mass before leading his army down to defeat the Turks in 1683. Sit on the terrace of the hotel for coffee and strudel and look at the fantastic view of Vienna, the River Danube and the Danube Canal.
