The diverse Ionian Islands

Scattered off the western coastline of central Greece and to the south of Peloponnese, the Ionian archipelago comprises large and small islands. The group consists of 14 islands in total. However, only 7 of them are the largest and most popular islands of the group:

  1. Zakynthos or Zante is home to the worldwide famous Navagio (Shipwreck) beach, gorgeous cliffs, and lush landscapes.
  2. Ithaca, the home of Odysseus (Homer's Odyssey), is famous for its many waterfalls. Hop on the ferry from Patras to Ithaca in 3.5 hours or from the port of Kefalonia in 25 minutes.
  3. Corfu, with heavenly pine-framed beaches and the popular Liston Square, is the capital of the Ionian islands. The Igoumenitsa - Corfu ferry will take you to the island in less than 1.5 hours.
  4. Kefalonia is known for the amazing quality of its local wines, idyllic beaches, glittering caves, and fresh seafood. Take the ferry from the port of Patras and reach the port of Sami in less than 3.5 hours, or catch a ferry from Kyllini to Kefalonia (Poros).
  5. Lefkada is famed for its stunning, white-sand beaches and turquoise waters, popular among windsurfers.
  6. Paxi (or Paxos) is a small island with the picturesque, little capital of Gaios. Jump on the ferry from Igoumenitsa to Paxi and explore the heavenly beaches of Paxi.
  7. Kythira, with the Venetian Castle above the Chora of Kythira, the island's capital.

You will need at least 4 days to explore each of the larger islands of Corfu, Lefkada, Kefalonia, and Zante, while you can spend a day on the smaller ones. For the larger islands, it is best to rent a car or a scooter to get around in total freedom and explore Venetian castles, ancient churches and secret coves.

You can also go island hopping and spend a day exploring Antikythera, Antipaxi, Ereikousa, Mathraki, Othonoi, Meganisi, or Strofades, which are the lesser-known islands of the Ionian archipelago.

The best time to visit the Ionian Islands is from June to September when the weather is sunny and warm. Especially, during July and August, the temperatures are high and the water is just perfect for summer dives and worry goodbyes. 

Tip: the average budget for two people visiting the Ionian Islands is €200 per day. This budget includes accommodation costs for 2 adults in a hotel, lunch, drinks, and entertainment.

The majestic Cyclades

The Cyclades are undoubtedly the most famous island group in the Aegean Sea. The archipelago includes many islands, so we better focus on the major ones. Among the most popular islands of the Cyclades are:

  • Mykonos is best known for its photogenic town and its vivid nightlife. You can take the Athens (Piraeus) - Mykonos ferry that runs twice daily, and reach the popular island in just 2,5 hours from Athens with a high-speed ferry.
  • Santorini, the windswept, volcanic island with its blue domes and the scenic white-washed houses. What are you waiting for? Catch the ferry from Athens (Piraeus) to Santorini to enjoy its unique sunsets over the caldera.
  • Milos, with its endless pirate tales, impressive catacombs, picturesque fishing villages, and lunar landscapes. Take the ferry from Athens (Piraeus) to Milos and dive into the mesmerizing waters of the instagrammable Sarakiniko beach. 
  • Syros, with the picturesque capital of the Cyclades, Ermoupolis and idyllic beaches, is just 3 hours from Athens. Jump on the Athens (Piraeus) - Syros ferry and take a stroll through the labyrinthine streets of Ermoupolis.
  • Paros, renowned for its cosmopolitan character and exciting nightlife, is 3-4 hours if you travel by ferry from Athens (Piraeus) to Paros.
  • Naxos, popular among kitesurfers and windsurfers and its impressive Portara doorway of the ancient Temple of Apollo, is worth the 5-hour trip by ferry from Athens (Piraeus) to Naxos.

The weather in the Cyclades during summer is hot with an average maximum temperature of 32°C. However, during July and August, prepare to feel the breeze of the meltemia, strong summer winds that are not the best for sailing boats. 

Also, the best way to get around Santorini, Mykonos and Syros is on foot or by bus while Milos, Paros and Naxos are better explored with a car. You will need 4-5 days to fully explore the islands of the archipelago. The Cyclades are the most popular and the most expensive Greek island group. Santorini and Mykonos are the most expensive islands on the list, usually with €300-€350 a day per person, but you might be also able to find a bit more afforable options there.

Tip: ferries also depart from the port of Piraeus to Crete, reaching the ports of Heraklion and Chania. Athens (Piraeus) - Crete ferries usually depart late in the evening and travel during the night.
