Fehmarn Travel Guide

Fehmarn has a nice aquarium which is worth a visit. They have a nice selection of tropical and fish native to the waters around Germany . Just recently they opened their new 4 million liter shark exhibit. That makes it the largest in Europe.
The other section of the aquarium feels small due to all the guests that it draws in the summer time but dont let the cramped feeling stop you from visiting.

Hours vary by time of the year. Check the website for details.
