Those who like to do sports will love Freiburg. In summer, the immediate and nearer surroundings of Freiburg, the local mountain "Schauinsland", the Kaiserstuhl and of course the southern Black Forest are ideal for hiking, climbing, cycling and mountain biking.
The nearby Black Forest is ideal in winter: the winter hiking trails are specially signposted so that the Black Forest can also be hiked in winter. Snowshoeing is also an experience in the Black Forest. The house of nature on the Feldberg offers guided tours and a rental of snowshoes and telescopic sticks. The southern Black Forest is ideal for skiing and snowboarding in winter: a well-developed and well-maintained infrastructure of ski lifts, slopes and cross-country trails can be reached quickly from Freiburg.
If you don't want to do without climbing in winter, there are various climbing and bouldering halls available.
