Petani Beach (also spelled Petanoi) is situated in the North West of the Paliki, in Kefalonia, Greece. The nearest large town is Lixouri.
The beach is set at the base of a very steep road, surrounded by mountains, in a curved bay with a strip of pebble and sand beach which is up to 50m wide in places. The beach is about 600M long, with the central part being used by swimmers.
Petani beach is recognised for its great beauty, with many visitors comparing it with a smaller version of Myrtos Beach. It is a blue-flag beach. A favoured activity is evening swimming before watching changing colours on the sea as the sun sets in the West.
The beach slopes quickly away so that one can only go out a short distance from the shoreline before being out of depth.
