North of the city lies the Vienna Woods (Wienerwald) - 1350 square kilometres of protected forest. It sweeps along the banks of the River Danube and heads towards the Austrian Alps and it’s a great place to walk and hike. Just choose your trail and set off for a day of spectacular views, good exercise and terrific fun. Stop and look back over the city, and keep an eye out for the birds, lizards, and deer that call the forest home.
