Whitewashed villages, blue-domed churches, crystal-clear water and golden sunsets make the Greek islands one of Europe's most dreamed-about destinations. Santorini and Mykonos are the most famous, but Greece has more than 200 inhabited islands, each with its own character. This guide will help you choose the right islands, plan your ferries and make the most of your time.
When to Visit the Greek Islands
The island season generally runs from late April to October. Many hotels, restaurants and ferry routes reduce service or close in winter.
- May and early June: pleasant temperatures, wildflowers and fewer crowds. The sea is still cool.
- July and August: hot, busy and the most expensive. Strong meltemi winds can affect ferries.
- September and early October: warm sea, softer prices and a relaxed atmosphere. Often the best time to go.

Santorini
Santorini is famous for its dramatic volcanic caldera, with towns perched on cliffs high above the sea.
Highlights
- Oia: the island's iconic sunset viewpoint. Arrive early to find a spot, or enjoy the sunset from a quieter location.
- Fira to Oia hike: a scenic cliff-top trail of about 6 miles (10 km) with incredible views.
- Akrotiri: a remarkably preserved Bronze Age settlement buried by a volcanic eruption.
- Red Beach and Perissa: distinctive volcanic beaches with red and black sand.
- Caldera cruise: sail to the volcano, swim in the hot springs and watch the sunset from the water.
Where to Stay
Oia and Imerovigli offer the most spectacular caldera-view hotels at premium prices. Fira is central and lively, while Kamari and Perissa offer beachside stays at lower rates.
Mykonos
Mykonos is known for its glamorous nightlife, beautiful beaches and charming main town.
Highlights
- Mykonos Town (Chora): a maze of white alleys, boutiques and small churches.
- Little Venice and the windmills: a classic spot for sunset drinks.
- Beaches: Paradise and Super Paradise for parties, Agios Sostis and Fokos for quieter swimming.
- Delos: a short boat ride to one of Greece's most important archaeological sites.
Where to Stay
Staying in or near Mykonos Town keeps you close to restaurants and nightlife. Ornos and Platys Gialos are convenient for beach lovers and families.
Other Islands Worth Considering
- Naxos: long sandy beaches, mountain villages, great food and better value.
- Paros: a relaxed alternative to Mykonos with pretty harbor towns.
- Milos: striking coastal rock formations and hidden coves.
- Crete: Greece's largest island, with ancient sites, gorges and varied beaches.
How to Get to the Greek Islands
By Air
Most travelers from the United States fly into Athens, then take a short domestic flight or ferry to the islands. Santorini and Mykonos also receive direct flights from many European cities in summer. Compare routes on SkylineSparrow flights.
By Ferry
Ferries leave Athens from the ports of Piraeus and Rafina. High-speed ferries reach Mykonos or Santorini in about three to five hours, while conventional ferries are slower but cheaper and more stable in rough seas. The ferry between Mykonos and Santorini takes around two to three hours.
In peak season, book ferry tickets in advance, especially for vehicles or specific departure times.

Money-Saving Tips
- Travel in May, June or September for lower hotel rates.
- Stay away from the caldera edge in Santorini and walk up for sunset views.
