Santorini and Mykonos in One Week

Most visitors treat Santorini and Mykonos as two separate trips. A week is enough to link them properly, add the one excursion that neither island can offer on its own — Delos, reachable only from Mykonos — and still leave slow mornings for the caldera and the whitewashed lanes both islands are known for.

Why pair these two islands

Santorini and Mykonos sit less than three hours apart by fast ferry, and both are served by direct flights from several European cities, which makes a two-island week logistically easy rather than ambitious. They are also different enough to justify the switch: Santorini is built around the caldera — a crescent of cliffside villages looking down into the crater left by the Bronze Age eruption — while Mykonos is flatter, beach-oriented, and built around its harbor town and its nightlife. Splitting a week between them gives you the caldera view, the Oia sunset, a Cycladic beach town, and a half-day at one of the most complete archaeological sites in Greece, without spending the whole trip on transfers.

This itinerary does not go deep into Akrotiri, Santorini’s south-coast beaches, or its wineries — those are covered in Three Days in Santorini: The Classic First Itinerary and One Week in Santorini Without Leaving the Archipelago for travelers staying on a single island. Here, Santorini gets the caldera, Oia, and one cruise; the rest of the week goes to Mykonos and Delos.

Day 1: Arrive in Santorini

Most flights and ferries land in the afternoon, so treat day one as a settling-in day rather than a sightseeing one. If you’re staying in or near Fira, walk the town’s caldera-edge promenade before dinner — it’s less crowded than Oia and gives you the same crater view without the crowds that build up for sunset further north. Book a table with a caldera view for the evening rather than fighting for one in Oia on your first night.

If your flight lands early enough, a short walk toward Firostefani is worth it: the path connecting the two villages is flat, shaded in parts, and quieter than the main square in Fira.

Day 2: The caldera villages and Oia

Spend the day working north along the caldera rim. Start early in Imerovigli, the highest of the cliffside villages, then continue toward Oia by bus or taxi for the afternoon. Oia’s blue-domed churches and narrow lanes are the single most photographed scene in the Cyclades, and they earn it — but the Kastro viewpoint fills up ninety minutes to two hours before sunset in high season. If you want the view without the crush, walk down to Ammoudi Bay instead, or watch from a quieter terrace back in Imerovigli.

For a guided route through Oia’s lanes and viewpoints without planning it yourself, a walking tour timed to the light works well:

For more ways to see the sunset without competing for a spot on the Kastro wall, see Oia Sunset Without the Crowds.

Day 3: Caldera cruise

Give one full day to the water. A caldera cruise is the best way to see Santorini’s cliffs from the angle they were formed to be seen from, and it typically includes a swim stop and time near the volcanic islets in the middle of the caldera. Half-day and sunset versions both exist; a sunset sailing timed around Oia’s cliffs solves the crowded-viewpoint problem entirely, since you watch the light change on the rock face instead of standing on top of it.

A day cruise around the caldera covers the swim stops and volcanic scenery in daylight, while a private sunset option works well for couples or small groups who’d rather not share the boat:

Full detail on what these cruises include and how they differ is in Santorini Caldera Cruise: Nea Kameni, Hot Springs and What to Expect.

Day 4: Ferry to Mykonos

Move to Mykonos today. High-speed ferries connect the two islands directly, with journey times that vary by boat and route rather than a fixed number of minutes — check current schedules rather than assuming a set duration, and book ahead in July and August, when sailings fill. Background on routes and operators is in Santorini to Mykonos: Ferry Times, Prices and the Delos Side Trip; if you’re building a longer Cyclades route around this trip, Cyclades Island-Hopping Routes from Santorini and Island Hopping from Santorini: Which Cyclades Island to Choose cover how the other islands connect.

Once you land, spend the afternoon in Mykonos town — Chora — getting oriented in Little Venice and the winding lanes around the old harbor, rather than planning anything more ambitious for a travel day.

Day 5: Mykonos beaches by boat

Mykonos’s coastline is best seen from the water rather than by chasing beaches one by one along the south coast road. A half-day boat trip along the south coast covers several beaches and coves in a few hours, with time to swim at anchor:

For a smaller, more private version of the same idea, a chartered catamaran covers similar ground at your own pace:

Spend the evening back in Chora — the town is compact enough to explore on foot, and dinner near the old harbor is a reasonable way to close out a boat day.

Day 6: Delos day trip

This is the day to plan around, not add on last-minute. Delos is reachable only as a day excursion from Mykonos, and it closes for a large part of the year on Mondays — check your excursion’s operating days before you book anything else for this leg of the trip, since a Monday booking here is the single most common planning mistake for this itinerary. No one stays overnight on the island: it’s a fully excavated archaeological site with no accommodation, so the whole visit happens within a few hours before the boat returns to Mykonos.

Delos was one of the most important sanctuaries in the ancient Greek world, and the ruins — a theater, mosaic-floored houses, the Terrace of the Lions — cover enough ground that a guided visit is worth it over wandering alone. Full planning detail, including how excursions are timed around the site’s opening days, is in Delos Day Trip: Is It Worth It From Santorini?.

Back in Mykonos for the evening, a slower dinner in Chora or a quieter beach for the last hour of daylight is a good way to close out the archaeology-heavy day.

Day 7: Last morning and departure

Use your final morning for whatever the week didn’t fit — a return visit to Little Venice at a quieter hour, a last swim, or last-minute shopping in Chora’s lanes. If your flight or ferry departs from Mykonos in the afternoon, there’s no need to rush; if you’re routing back through Santorini first, confirm ferry timing the day before, since inter-island schedules shift by season.

If two islands whetted your appetite for more, a longer Cyclades route — Naxos, Paros, or the smaller islands — extends naturally from either end of this trip; see Cyclades Island-Hopping Routes from Santorini for how those connect.

Booking notes for this route

A three-course dinner cruise is a way to combine the boat day with an evening out rather than a separate dinner reservation in town, if you’d rather not plan a restaurant for one of the Mykonos nights:

Two practical notes apply across the whole week. First, Santorini’s cruise-ship arrivals and its own sunset crowds mean the caldera villages are busiest from mid-morning to late afternoon on peak days — the villages on both islands are more pleasant early or after most day-trippers have left. Second, Santorini experienced a seismic swarm in early 2025 that closed schools and prompted temporary departures; it ended without an eruption, and researchers have linked it to underground magma movement rather than any current volcanic threat. It’s worth knowing about, not worth planning around.

FAQ: Combining Santorini and Mykonos in a Week

Do I need to book the Santorini–Mykonos ferry in advance?

In July and August, yes. High-speed catamarans run several times a day in peak season but fill up, and a missed sailing can cost you half a day. In the shoulder months, buying a day or two ahead is usually enough.

Can I visit Delos on any day of the week?

No. Delos closes for a large part of the year on Mondays, so build your Mykonos days around that before booking a boat. Excursions also depend on the meltemi wind, which can cancel crossings with little notice.

Can I sleep on Delos to see it without crowds?

No one stays overnight on Delos. It is a fully protected archaeological site with no hotels or tavernas, visited only as a day excursion from Mykonos, so plan to see it and return by boat the same day.

How many nights should I spend on each island?

Three or four nights on Santorini and three or four on Mykonos is the common split for a week. Santorini rewards slower mornings around the caldera; Mykonos works well with two or three focused days plus the Delos excursion.

Is this itinerary better than staying only in Santorini for a week?

It depends on what you want. This route trades depth on Santorini’s south coast and wine country for the contrast of a second island and Delos. For a single-island deep dive, One Week in Santorini Without Leaving the Archipelago covers that ground instead.

Do I need a car for this itinerary?

No. Between buses, the caldera cruises, and Mykonos being compact and walkable from most bases, a rental car is not necessary for this particular route.
