This excursion is an ideal introduction to the city's highlights. Reach the natural fortress of the Acropolis, and with your guide you will walk up the uneven footpath heading to the summit. Sights include the Propylaea, Temple of Apteros Niki, Erectheum and the Architectural Triumph of the Parthenon. Continue with a city drive and see Constitution Square, the Tomb of the Unknown Soldier, Royal Palace, Hadrian's Gate and the Old Marble Olympic Stadium. After lunch, drive along the scenic coastal road which affords splendid views of the Saronic Gulf and takes you through some of Athens' most beautiful suburbs. Arrive at Cape Sounion to visit the Temple of Poseidon, standing some 200 feet above the sea at the edge of a cliff. It is one of the most breathtaking and deeply moving sights in all of Greece. Fifteen of the original 34 columns of the Doric order still stand in majestic splendor. Note: The Acropolis is explored on foot and requires approximately two hours of walking. There are some 75 steps at the entrance and in certain locations the marble is uneven and slippery. We advise that you bring a bottle of water and suitable sun protection. This tour may be slightly shortened during winter months due to the time in port.
