Fragkocastelo is a small, sparsely populated settlement at the south of Chania county and home to an impressive Frankish castle. The White Mountains are behind it and the Libyan Sea lies at its feet. The beaches are vast and give the impression of being tropical. From time to time, locals report strange optical phenomena, such as seeing riders moving along the side of the castle. Some say these are reflections from the African coast and others believe they are just optical illusion caused by humidity.
