Don’t get too stressed out seeing whatever the sights are, just relax and drink beer. The freshest beer straight from the brewery is on Beer Street… also visit Zhongshan Park, the German district, the Tsingdao brewery museum (maybe), but go to Beach No. 6 (even though it will be crowded you can catch some sun).

There're loads of ways. Why not searching the already existing websites with loads of tipps for things to do in Qingdao?

i.e.: Little Qingdao (island), shopping in Taidong, hiking in the Laoshan area, go to the small park behind shi lao ren beach (old stone person beach). it's a little outside town on the east, hiking in fushan area....
