The GR 7 long-distance trail, E 4 E-path, comes all the way from the Peloponnese (in Greece), starting at the temple of Delphi. It is just over 6,000 km long and it crosses the Mediterranean arc, passing through Bulgaria, Serbia, Croatia, Slovenia, Italy, France and Andorra. Once you make it through the Pyrenees mountain range, this trail runs through the Spanish Mediterranean regions as far as Tarifa.
