It’s not too early to start planning autumn travel and Peter Sommer Travels should be on your radar. The cruise and tour operator takes guests on journeys through Croatia, Greece, Italy and Turkey, focusing on archaeology, nature and food. Cruise the Cyclades or Dalmatian Coast, walk to ancient sites in Turkey or enjoy delicious dishes in Sicily.

“Autumn is a truly wonderful time to get away to our Mediterranean destinations,” said Peter Sommer, founder, Peter Sommer Travels. “The heat of summer has abated, but the sea is beautifully warm for swimming. The school holidays are over, so archaeological sites and museums are less crowded. And the seasonal harvest is underway, providing a cornucopia of culinary delights.”
