Drosia is a mainly residential suburb, known for its location in the midst of evergreen pine forests. During the extreme heat of Greek summers, many people from the whole Athens urban area drive up to Drosia on the weekends, seeking cool and shade in the taverns, cafes and one outdoor cinema theater, for which the area is known.
