The Athens Big Bus Hop-On Hop-Off Sightseeing Tour lets you explore Athens, Piraeus, and the Athenian Riviera at your own pace aboard a bright, open-top double-decker bus. With over 40 stops across three routes — Athens (city sights), Piraeus (port and waterfront), and the Riviera (coastal views, beaches) — you can hop on and off wherever you like to dive deeper into the places that interest you most. You’ll visit iconic landmarks such as the Acropolis, the Parthenon, Temple of Zeus, Plaka, Monastiraki, and others. Commentary is provided via multilingual audio guides so you’ll hear stories and history as you go. Tickets are flexible and often valid for 48 to 72 hours, with some options including night tours to see Athens beautifully lit after dark. It’s a comfortable, informative way to get an overview of Athens and its neighbouring coastal charms, especially good if you want structure without being tied down to one itinerary.
