What can be seen in Cassandreia? Are there any secret places?
Are you referring to Cassandra, the peninsula?
There, the beaches are mostly different.
However, I think it's worth mentioning the thermal springs in Loutra Agias Paraskevi, and there is also a beach where fish abound (near these springs), as well as fish taverns in Loutra itself, and also in the nearby fishing village of Nea Skioni.
