Methoni´s Venetian Castle catches the eye. Visit this beautiful castle and take your time, for it is bigger than you might think. Closed on Mondays, but open the rest of the week for just a small fee. Look at the sea surrounding it and feel the history.
Ancient Greece is not far away. Take a daytrip to the old town of Pylos (including another Venetian Castle), Nestors Cave and Castle, Ancient Olympia and Ancient Messenia.
