During my recent trip to Gdansk I managed to convince my father to visit Gdynia. Initially, my father was more inclined to visit Sopot and stroll on its wooden pier (apparently the lonest one in Europe) as he thought that Gdynia being an industrial city had nothing to offer. Luckily, Gdynia proved him to be wrong and we had a great time there. Especially, we enjoyed visit to the harbor and watching a few of Polish most famous historic ships/sailboats.
