I have already booked tours around the Danube Delta in Poland. I decided to go on all-day motorboat trips along two branches - Sulina and Sfantu Gheorghe. It was a fantastic adventure. Although the captain liked speed and didn't swim too close to wild birds, I still managed to take some nice photos. An unexpected attraction was the wreck of the Georgian-flagged ship Turgut S, which in 2009 ran aground at the mouth of the Danube into the Black Sea.
