This area is hardly visited by tourists and has kept its original character.
Take the old road from Argos to Tripolo. A few km past Mili there is a sign indicating the road to Velanidia, Andritsa and Elaiochori. Drive on till a sign tells you to go down right to the old station of Andritsa. At the end of the road you find the railway station as well as a mushroom greenery and past the station a monument for the people that died just after the war in the Greek civil war. The railway is out of use since 2010 but will probably get a new life transporting tourists on this very beautiful trail. The cache is a plastic food container.
