Some sights are:
The ancient citadel of Asini is located on the top of the hill next to sea, about a km before Tolo. With a intense life from the early years of the Bronze Age, as it was shown by the findings of excavations, reached the top during Mycenaean Before Geometric and Geometric years. The ancient city was mentioned by Homer in the Iliad, and was the inspiration of Nobel laureate poet George Seferis for one of his most emotional poems. Today are distinguished traces of prehistoric settlement, parts of the imposing enclosure of Polygon structure of the acropolis, as well as Hellenistic towers that retain their medieval repairs. On hill opposite the Acropolis have been excavated Mycenaean, Hellenistic and Roman tombs.
The chapels of "Metamorphosis tou Sotira", 16th century, northwesterly of Asini, and the Prophet Elias, at the top of the hill nearby.
The noble stone house, the tower of Agas or Pyrgospito of Candia dominates and is one of the most impressive buildings that remain untouched by time in the region.
The hill "Eleousa" where the traces of earlier years are still there as there are ruins of the Candia Acropolis from the Mycenaean era.
The Signal Tower (Fryktoria) of the 7th century BC, that someone can see as approaching Iria on the left. The tower is maintained in good condition until today. It was used to communicate with other similar towers to alert, with smoke signals during the day and with fire signals during the night, the Ancient Asini and Mycenae in case of enemies raids.
It is worth to make tour with a boat in two small islands located within the bay of Tolo. In island Romvi there are pieces from the medieval castle walls, while in the island Daskalio years ago operated an orthodox seminary.
Tolo, due to its geographical position can be a base for your acquaintance with the most important archaeological sites and historical monuments of Argolis (Argos, Mycenae, Epidaurus, Ancient Asini, Náfplion).
Also, during the summer tours, with small boats, to the islands of the Saronic Gulf (Hydra, Spetses and Poros), are organised regularly.
