With 3,000 years of history, you can’t turn around in Athens without encountering the past. The Acropolis, a UNESCO site, the Plaka, and the Acropolis Museum are must-sees. But leave time if you can to climb Pnyx Hill for photos of the Parthenon at sunset, to buy your own set of Greek komboloi (worry beads), and to explore the metro stations that serve as mini-museums for the relics that are constantly being unearthed. 

This Gibraltar-like town tied to the mainland by a single thread of causeway holds treasures that are old even by Mediterranean standards, with town walls and several churches dating to the 12th century. Climb to the upper town for an up-close look at the castle and Agia Sophia, a Byzantine church. Wander the lanes of the lower town lined with Venetian mansions, many of which have been lovingly restored. Savor the sun on a smooth pebble beach. 

Charming and scenic Katakolon is the gateway to Olympia, the original home of the Olympic Games and a UNESCO World Heritage Site. You can visit this memorable site only 30 minutes away and see the fertile Peloponnese valleys along the way, full of strawberries, tomatoes, corn and olive trees.

One of the most beautiful and popular islands, located on the Ionian Sea, Corfu has wonderful beaches and small villages throughout the island. Take in the Venetian influence at the two fortresses located in Old Town, a UNESCO World Heritage Site. 

While larger ships must pass by, we anchor right beyond the famous walled city so you can admire its beauty with every glance. Tender ashore and step right into Old Town, a UNESCO site where no cars are allowed, just eons of history. Capture the exhilarating views on your camera — and in your memory. End your day at the Buza Café (if you can find it) watching bold divers leap off the cliffs into the crystalline sea. 

Celebrities from Prince Harry to Beyoncé have made Hvar their go-to place. Follow the city walls to sweeping views from the fortress on the hill. Head to the town square for a look at the Venetian Cathedral or find the large bay of Stari Grad on an optional tour to this famous UNESCO site. 

Something here will capture your heart. A Roman amphitheater, 9th century churches, and museums packed with Byzantine-era artworks crowd the peninsula that tidily contains the Old Town. It’s a tempting way to spend the day for sure. While away the day listening to Zadar’s giant Sea Organ, a haunting musical improv performed by the surging Adriatic or share a bench with a sun-drunk cat as you bite into a truffle.

The lovely fishing port of Rovinj on the west coast of the Istrian peninsula bordered on three sides by the Adriatic Sea. You can tour the maze of cobblestone streets that lead to the hilltop St. Euphemia Cathedral with its towering steeple dominating the skyline. Old Town Rovinj is a delightful tangle of medieval streets and twisting stairways. Seek out the Bronze Age ruins of Monkodonja, the hidden beaches or the breathtaking natural beauty of the 6-mile-long Lim Fjord.

No other sea approach in the Adriatic raises goose bumps like Venice, a small ship exclusive where the entire city and its lagoon are a UNESCO World Heritage Site. On your luxurious home-away-from home, you arrive already equipped with a sense of what it’s like to live in the city that’s neither land nor water. Add your own sigh to the Bridge of Sighs, sip a spritz al bitter as you plot your agenda, and let the water taxis do your navigating unless you don’t mind getting lost. Not such a bad prospect, with serendipitous discoveries around every corner.
