Sightseeing in Athens can be hard work, especially in the heat. View its highlights more easily with a 24- or 48-hour hop-on hop-off bus tour. Take a seat, enjoy the audio commentary, and hop off at stops to explore the Acropolis, Plaka, and more. Plus, enjoy included walking tours, and upgrade to enjoy an Athens-Piraeus circuit with cruise port stops or an Athens-Piraeus-Glyfada circuit including Athens’ Riviera beaches.
