Nice and quiet
There are several ways to get to know Dubrovnik. You could try walking around the city, or looking from above the rooftops of the city walls, but you can also go by water, thanks to these glass boats. The boats can be taken from the old town, and go on a journey around the city walls. You'll see not only the city and its surrounding area, but also the bottom of the sea, thanks to the glass bottom: you can observe fish and starfish passing underneath you. The tour is not very long but very nice and quiet. Recommended!
