The beach promenade of Nafplion is a paved path connecting the town's small port with the beach of Arvanitia. It is a lovely coastal alley carved in rocks offering amazing sea views as well as different views to all the fortresses of the town: Acronafplia, Bourtzi and Palamidi.
On your way, you will encounter massive fields of prickly pears, small swimming spots as well as huge, orange-hued rocks that are very popular among climbers.
Also, you will find a small chapel dedicated to Holy Mary that many locals assume served as a "kryfo sxoleio" which means a "forbidden school" teaching Greek during the Ottoman occupation.
Note that although this promenade is one of the most beautiful parts of Nafplion, some landslides occur now and then. You will see warnings and fences preventing visitors from entering.
If you want to walk more, the same path continues further from Arvanitia to Karathona beach. It is long and unpaved but easygoing while the sea views and the pine trees will keep you good company throughout your way. You will find small and remote beaches such as "Neraki" and climbing spots on your way.
Last but not least, at the entrance of this path, you will notice ruins of an old restaurant that was built in the '60s by a famous modernist architect. Unfortunately, it remains abandoned.
