Greece has two islands that dominate every summer conversation and almost every Instagram feed — Santorini and Mykonos. Together they receive millions of visitors every year and are consistently named among the most beautiful places on earth. They are also completely different from each other in ways that make choosing between them genuinely important for your holiday experience.
Go to the wrong one for your style and you will have a perfectly pleasant but not quite right holiday. Go to the right one and Greece will exceed every expectation. This guide tells you honestly which is which.
🏛️ Santorini or Mykonos First?
Santorini is the most photographed island on earth — caldera views, white domes, the Oia sunset. Mykonos is the Mediterranean's great party island — cosmopolitan, glamorous, expensive and completely unashamed about what it is. Here is how to choose.
Quick Answer — Who Should Choose Which

|---|---|---|

| 🏖️ Beaches | Mykonos | Better, more varied beaches with beach clubs |
| 🏛️ History & culture | Santorini | Ancient Akrotiri ruins, volcanic island geology |

🌋 Santorini — The World's Most Photographed Island
Santorini is the remnant of a volcanic caldera — a crescent-shaped island surrounding a flooded volcanic crater of extraordinary beauty. The villages of Oia, Fira and Imerovigli cling to the caldera rim — white cubic houses, blue-domed churches and infinity pools overlooking the collapsed volcanic crater flooded with sea. The sunset from Oia is genuinely among the world's great natural spectacles — the light goes from gold to orange to deep red as the sun drops behind the caldera rim and hundreds of people spontaneously applaud. The ancient ruins of Akrotiri — the Pompeii of the Aegean, a Minoan city buried under volcanic ash — are extraordinary and visited by a fraction of the island's tourists.
Santorini Pros and Cons
- Caldera views — simply the most spectacular island scenery in the Mediterranean
- Most romantic destination — private plunge pools, cave hotels, cliff-top dining at sunset
- Volcanic geology — unique black and red sand beaches, sailing to the active volcano
- Extremely crowded in summer — Oia's sunset attracts thousands, cruise ship passengers flood Fira daily
- Expensive — caldera-facing accommodation is among the most costly in Greece
- Not a beach destination — beaches exist (Perissa, Kamari) but are not the island's strength
🎉 Mykonos — The Mediterranean's Great Party Island
Mykonos is the most glamorous, cosmopolitan and expensive island in Greece — a place where the world's most famous DJs play beach clubs at noon, where designer boutiques line the labyrinthine streets of Mykonos Town, where the beaches at Paradise and Super Paradise throb with music from 11am and where the all-white Cycladic town hides the most famous windmills in Greece behind winding alleys. Mykonos is also the Mediterranean's most celebrated LGBT destination — openly and proudly so for decades. The island does not do quiet.
Mykonos Pros and Cons
- Best beaches in the Cyclades — organised beach clubs, water sports, lively atmosphere
- World-class nightlife — beach clubs, bars and clubs running from noon through to dawn
- More cosmopolitan — international celebrity crowd, designer shops, Michelin-starred restaurants
- Most expensive island in Greece — cocktails €20+, dinner €60+ per person, accommodation very costly
- Not as visually spectacular as Santorini — beautiful but lacks the caldera drama
- Not family-friendly — the party atmosphere is the main event. Families with children are not the target market

🚫 Mistakes When Visiting Santorini and Mykonos
Fira is the busy commercial capital of Santorini — good for transport connections and budget accommodation but lacking the drama and beauty of Oia. The difference between a caldera view from Oia at sunrise and watching the same view from Fira's busier, less refined streets is enormous. If budget allows, stay in Oia, Imerovigli or Firostefani for the authentic Santorini experience. Even one night in a caldera-view room in Oia will transform your understanding of why people become obsessed with this island.
Mykonos beach clubs charge entry fees of €30–€80 per person just to access the organised beach areas at Paradise and Super Paradise. Inside, cocktails cost €18–€25 each and a sunbed rental adds another €20–€30. A full day at a Mykonos beach club for two people costs €200–€400 before you consider food. This is not a hidden cost — it is the main event of Mykonos. Go knowing this and budgeting accordingly. Go expecting a budget beach day and you will be genuinely shocked.
Santorini's old port is at the base of 588 steps carved into the caldera wall. There is a cable car but the queues in peak season are significant. Donkeys also transport luggage but their welfare is a concern — the PETA-documented practice of overloading donkeys has been widely criticised. The practical advice: take the cable car, arrive via the island's main port (which serves larger ferries directly to the modern port), or fly in — Santorini's airport is small but receives flights from Athens and several European cities directly.
Ferry connections between Santorini and Mykonos exist but the journey takes 2–3 hours each way. Spending 2 days on each island in a 4-day trip means two of those days are spent on ferries and arriving tired. Both islands deserve minimum 3–4 days each — preferably a week on each — to experience properly. If time is limited, pick one. A week in Santorini or a week in Mykonos is a substantially better holiday than 3 days in each.
The famous sunset viewpoint in Oia fills up 2–3 hours before sunset in peak season — people arrive with picnic blankets and stake positions. If you want a sunset dinner at a caldera-facing restaurant in Oia during July or August, book the restaurant months in advance — the best tables are reserved as soon as the booking window opens. This is not an exaggeration. Alternatively, watch the sunset from a caldera-view room in your accommodation — often better than the crowded viewpoint and completely free.
Santorini produces some of the finest white wine in Greece — the Assyrtiko grape grown in the island's volcanic soil creates wines with extraordinary minerality and acidity unlike anything produced elsewhere. Santo Wines and Estate Argyros are the two most respected producers with stunning caldera-facing tasting rooms. A wine tasting at sunset with a caldera view costs €25–€35 per person including multiple pours — genuinely one of the best value experiences on the island and missed by most tourists who never go beyond the tourist strip restaurants.

✅ Final Verdict
For most first time visitors to Greece — and for honeymooners, couples and photographers anywhere — Santorini. The caldera. The Oia sunset. The cave hotel with a plunge pool overlooking the crater. These things genuinely live up to the photographs in a way almost nothing else in Mediterranean travel does. For the party, the beach clubs, the celebrity scene, the Mediterranean glamour and the world-class nightlife — Mykonos. If you have two weeks: do both. Do Santorini first, experience the quiet awe of the caldera, then travel to Mykonos and dance until dawn on Paradise Beach. This is the ideal Greece itinerary and it is magnificent.
