[3] The main thoroughfare is Mesogeion Avenue, which connects Cholargos with central Athens and the A6 motorway.

Because of its location at the base of mountain Hymettus, Cholargos is strongly influenced by cold air masses that travel down the mountain, hence it is cooler that most of Athens, like downtown Athens or seaside locations.
