I'll be travelling with my girlfriend to Europe for two weeks in the beginning of August, we are starting out in Barcelona, then move to Lyon, next Bern and last Stuttgart, we'll stay about 3 days at each location and aside from seeing the regular stuff, we'd like to do other things that not too many tourists see, like something locals do, I love learning about each location's culture and customs.
Also if you have suggestions about main attractions, please feel free to write them down. Thanks
