Few places manage to capture the world's imagination quite like Greece, a land of sun-kissed coastlines, tranquil whitewashed villages, lively seaside towns, and well-preserved ancient sites. One of the world's top tourist destinations since ancient times, the country draws nearly 20 million visitors each year. Athens, the birthplace of Western civilization, continues to attract the biggest crowds and serves as a base for exploring the country and its 227 inhabited islands. Away from its cities, Greece features a picturesque countryside of olive groves, vineyards, and tiny settlements nestled against rolling hills and rugged mountain ranges. Explore the old mainland on foot and discover the islands on a guided boat or ferry tour.
