Perokopió or Marmaro is a large and pleasant cove located 2.1 nM SE of Kampí. It provides reasonable shelter (but not as good as Kampí). On the shore there is an ancient marble quarry. Anchor in 3-6 m. Good holding. Warning: Be careful of the submerged foundations of the ancient harbor on NW side of the cove. It is easy to visit the ancient quarry where there are a number of unfinished column drums. There is no GSM/GPRS signal here. To make a call you must climb up the hill.
The harbor of Fourni gets a fair amount of swell with the `meltemi (the Etesians)` and to compound the problem its rocky bottom with a thin layer of mud provides poor holding.
The best place for a yacht is alongside the southern side of the ferry jetty at the SE side of the harbor, where there is space for two yachts to raft up, or (if a ferry is not parked there) alongside the northern side of the same jetty.
