praia do preventório is a
small beach located in
niterói, on the
guanabara bay side of town facing the charming
são francisco
(são
francisco's harbor).
only 350 meters in length, and together with the adjacent praia da
praia da samanguaiá, this beach is often referred to as
'praia da reia grossa,' or beach of the rough sand.
this beach has calm waters, fine white sand, and
many palm and chestnut trees along the shore, however it is not a
particularly developed or attended beach in the area.
