How I like to spend my leisure time in Graz: :
1. A jog or a walk along the river Mur at the Augarten in the evening,
2. Sunset or sunrise with a nice view of the city on the top of Schlossberg,
3. Various jazz sessions/live latin music at one of the many pubs in the city,
4. Museum visits and shopping at the city center, or a visit to the garden at the Eggenberger Palace
5. Billiards, darts, chess and other games at one of the many sport-bars in the city
On the website of the City of Graz you can find information in German on sports facilities, outdoor activities, parks and gardens and local recreation areas.
