Enjoy one of the many nature offerings, all of which can be reached by foot from the city: Botanisk Have The Botanical Garden, Universitetsparken The University Park, Vennelystparken, Riis Skov Riis Forest or Havreballe Skov Havreballe Forest. The beautiful 8 km. stretch of forest south of the city is equally suited for a hike, especially the old forest around the Moesgård Museum and Skovmøllen Forest Mill. The Brabrand Lake is ideal for biking and rollerskating, as there are 10 km of flat paths without any car traffic.
Aarhus University
There are many colleges and schools of higher education in the city, the biggest of which is Aarhus University (http://www.au.dk/en) Da. Aarhus Universitet, with around 35.000 students, also including the Aarhus School of Business (http://www.asb.dk/). This means that the city is crowded with students.
Learn Danish in the Universitys Danish Courses (http://www.au.dk/en/is/le...) or in the LærDansk (http://www.laerdansk.dk/en/).
