Eleouthkia is a private-enterprise botanic garden which, in my opinion, surpasses many municipal gardens throughout the world in the wide range of plants on view, its striking vistas, and its person-friendly layout. Amazingly, the entrance lies just off the A6 motorway exit to Mandria (watch out for the Eleouthkia sign on the roundabout itself) and the whole garden lies next to the motorway (but is “in a different world”)! If you want to buy plants to take home, there’s a big plant nursery adjacent to the garden park
