Poseidon Sanctuary

Located in the center of Poros island, this archaeological site is where the Temple of Poseidon Kalavreatis used to be. Nowadays there are only ruins but visitors can also admire the stunning views of the Saronic Gulf. Entrance is free.

Nemo Semi-Submarine

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.

Seashell Exhibition

The permanent exhibition "Shells & Sea", unique of its kind in Greece, is housed on the ground floor of the Hatzopouleio Municipal Library, on 28th October Street (1st parallel to the main road). The exhibits include Greek and foreign shells from the collection of Georgiou and Helgas Kanellakis, while the exhibition is enriched with photographs, fossils, minerals and also archaeological finds from the Aegean region.
