In Poros, both children and older children can experience a unique experience: the ride on a submarine. In fact, it is a semi-submersible since it does not completely submerge, but only the lower part, which through the large windows gives the feeling of a real dive while watching the sea bottom. The semi-submarine Nemo starts from the port of Poros going along the coast and ends there again, in a journey of about half an hour. Routes run daily (except Wednesday) from 10:00 to 22:00.
