Fortica (Old Town)
Omiš used to be surrounded by walls, which were mostly destroyed in the 19th century, but the remains can still be seen at the top of the Omiš Dinara. Above the walls are two fortresses, Fortica and Mirabela, which can be reached on foot from Omiš. It will take you about an hour to get to Fortica, and ten minutes to Mirabela.
