The blue Danube (which is actually not that blue) is an ideal green oasis for those who want to escape the city. Take the metro line U1 and get off either at Alte Donau metro station or at Donauinsel.
What can you do there? Invite your friends and host a barbecue (but remember to reserve a place in advance), have a dinner at the restaurants (I like this one for the atmosphere) and cafes directly on the waterfront, do some water sport or go swimming or jogging, rent a pedal or an electric boat for a super romantic ride on the water or just sit on a bench, relax and gaze at the sunset.
I shouldn’t forget to mention the Donauinselfest, which is an open-air free music festival that takes place every summer and lasts for three days.
On the photos above, I gladly share some snippets of my last visit to the blue Danube.
