This is the oldest city in Europe and one of the most compelling places in the world to explore. Cruise to Athens and you'll discover a bustling metropolis that blends vibrant street life with iconic ancient attractions. Many of the top sights are located in the historic center of the city, which serves as a massive archaeological park.

Be sure to budget plenty of time to explore the Parthenon and the Acropolis, which lure more than 7 million travelers every year. And if you want to avoid the crowds – and the heat–arrive at these immensely popular sites as early as possible.

Tour the crumbling remains of the massive Theatre of Dionysus and then explore the Ancient Agora of Athens. And if you'd like to take a break from venturing into the past, there are also plenty of other attractions in the city.

Mingle with Athenians while shopping at the Monastiraki market, where vendors sell everything from jewelry to original artwork. If you prefer more upscale retail, head to the neighborhood of Kolonaki instead.

With its remarkable blend of ancient and modern attractions, an Athens shore excursion is unlike any other experience.
