A trip to Greece is typically split between the historical treasures of the mainland and the idyllic beauty of its islands. Athens is a must-see for the Acropolis and Parthenon. From there, travelers explore world-famous island groups like the Cyclades, home to the iconic sunsets of Santorini and the vibrant nightlife of Mykonos. Greek cuisine, based on fresh produce, olive oil, and seafood, is a highlight. The ideal time to visit is during the shoulder seasons (spring and fall) to enjoy mild temperatures and fewer crowds.
