The Navpaktos port (Port Code:GRNAV) is a small and picturesque port and has the shape of a horseshoe with an opening of 35 meters. Left and right to the entrance are two towers. After the city’s liberation in 1829 the port still remained an important transportation and commercial centre that gave live to the city. Transportation to the shore of Achaia, Psathopyrgos and Patras were made by small boat. Also for many years the transportation with the prefecture capital Mesologgi, was made with small boats from Nafpaktos to Patra and from there to Kryoneri – Galata and then through local roads one could reach Mesologgi.
At the outer harbour of Nafpaktos large ships with goods arrived which were transported to the villages of mountainous Nafpaktia and Dorida. These activities gave life to the port and the surrounding area, Stenopazaro.  This situation lasted until the middle of the 20th century, and more specifically 1947, when the ferry Rio – Antirrio was created.  Today the small picturesque port accepts daily dozens of small cruise and sailing ships with European travellers especially during the summer months.
