The best Santorini day trips range from a caldera cruise to the active volcano and hot springs to the quiet island of Thirassia, and ferry day trips to nearby Ios and Naxos. There is plenty to explore beyond the main island. This guide covers the top excursions, the islands and how to plan a day trip from Santorini.
Day trips add variety to a stay, a rewarding part of the wider Santorini travel guide. The caldera and nearby Cyclades beckon. The sections below cover the options.
What are the best day trips from Santorini?
The best day trips from Santorini are the caldera boat cruise to the volcano and hot springs, the quiet island of Thirassia, a catamaran sailing cruise, and ferry day trips to Ios, Naxos or Folegandros. The volcano cruise leads the list every time.
Santorini day trips split into two clear families, and knowing the split makes planning easy. The first family stays inside the flooded caldera: the volcano and hot springs boat, the sunset catamaran, and the ferry hop to Thirassia. These trips put you on the water at the heart of the caldera, where the sheer painted cliffs, the dark volcanic islets and the deep blue water tell the island’s dramatic geological story from the best angle of all.
The second family leaves Santorini entirely, using the fast ferries that connect the island to its Cycladic neighbours. Ios sits closest, followed by Naxos, Folegandros, Milos and larger Crete to the south. Each destination has its own character, from Ios beaches to Naxos mountain villages, and each rewards a traveller who has spare days on the island and a flexible plan. The Santorini caldera shapes every water-based option here.
What is the volcano and hot springs boat trip?
The volcano and hot springs trip is a half-day caldera cruise to Nea Kameni, where you hike up to the craters, then swim in the warm springs at Palea Kameni. It is a fun, active outing and a firm favourite with families.
The volcano and hot springs boat makes the classic half-day on the water. Boats leave from the Old Port below Fira and head out to Nea Kameni, the bare, brown-black islet at the centre of the caldera, where a marked path of volcanic gravel climbs steadily to the crater area among rising sulphur fumes. The lava fields underfoot are among the youngest ground in Greece, and the guide points out the vents that still steam today.
The cruise then anchors off Palea Kameni so you can swim in to the warm, rust-coloured volcanic springs, where iron-rich water stains the shallows a deep ochre. The basic group tour runs a couple of hours, while catamaran versions add extra swimming stops and more comfort on board. It is a memorable, active trip and a hit with children, set out alongside the guide to the Santorini volcano and the Santorini hot springs.
Bring water shoes for the sharp lava path and a swimsuit worn under your clothes for the springs stop. The ochre water lightly stains fabric, so an old swimsuit works best. The trip pairs naturally with the wider range of Santorini cruise port departures.
Can you day trip to Thirassia?
You can day trip to Thirassia, Santorini’s quiet sister island across the caldera, by small ferry from Ammoudi Bay below Oia or the Old Port. It is the finest way to leave the crowds behind for clifftop villages, old churches and seaside tavernas.
Thirassia is the perfect antidote to Santorini’s crowds. The small island just across the flooded caldera, once part of the same landmass before the great eruption split it away, is home to only a few hundred people and has stayed almost untouched by tourism. There are no cruise-ship queues, no cable car and no coach parties, just a slow rhythm of fishing boats, goats and church bells.
A day trip runs by the small public ferry from Ammoudi Bay below Oia or from the Old Port, and the crossing is short. Boats land at the little port of Riva, from where steps climb to the peaceful clifftop village of Manolas with its traditional houses, sweeping views back to Oia and a handful of family tavernas serving grilled fish and local wine. Caldera cruises also stop at Thirassia for lunch, so you can taste the island even on a boat tour.
Once ashore, the island rewards slow wandering. Footpaths link Manolas to the old harbour at Korfos, to quiet chapels perched on the cliff edge, and to a scattering of cave houses carved into the rock. There are no crowds to hurry you along and no tour coaches to dodge, just goat tracks, wildflowers in spring and the sea far below. Bring water and sun cover, since shade and shops are scarce, and time your walk around the ferry back so you never risk the last boat. Thirassia is the day trip for anyone who found the main island too busy and wants Santorini as it once was.
Check the limited ferry times carefully before you commit to a self-guided crossing, since sailings are few and the last boat back leaves early. The full picture sits in the guide to Thirassia, reached most easily from Ammoudi Bay. Other Cyclades islands lie within ferry reach too.
What is a caldera catamaran cruise?
A caldera catamaran cruise is a relaxed half-day or sunset sail around the flooded crater, with swim stops at the Red Beach, a soak in the hot springs, and an onboard meal. It is the most comfortable way to see the caldera.
The catamaran cruise upgrades the volcano boat into a full day on the water. A sailing catamaran carries a smaller group than the big group boats, and the pace is unhurried. The route curves along the base of the multicoloured cliffs, passing the crimson cliffs above the Red Beach, the pale pumice of the White Beach, and the lighthouse at Akrotiri on the island’s south-western tip.
Swimming and snorkelling stops punctuate the sail, and most catamarans include a soak at the warm hot springs and a cooked meal served on deck as the boat drifts. The sunset version times the return so you watch the sky burn over the caldera from the water, away from the packed terraces of Oia. It is a strong pick for couples and anyone who wants comfort over budget, and it links naturally to Santorini watersports and a swim at the Red Beach.
The catamaran also solves a problem the group boats leave open, which is where to watch the sunset without a fight for space. The clifftop paths of Oia jam with visitors every evening, and a good spot demands an early arrival and sharp elbows. From the deck of a catamaran you drift into the same view with a drink in hand and open water around you. That single advantage wins travellers over, and it explains why the sailing trips carry a higher price than the plain volcano boats. Book the sunset departure rather than the daytime one to make the most of it.
Which islands can you reach by ferry day trip?
By ferry day trip you can reach Ios, the closest and easiest island, then Naxos, Folegandros, Milos and larger Crete to the south. Ios and Naxos suit a comfortable day out; Folegandros, Milos and Crete need an early start and a tight schedule.
Santorini’s position in the Cyclades opens up island day trips by fast ferry. Ios sits closest, a short high-speed hop away, known for its golden beaches and its hilltop Chora of white lanes, bougainvillea and old churches, lively in peak season but relaxed in the shoulder months. It is the simplest island to visit and return from within a single day, covered in the guide to the Santorini to Ios ferry.
Naxos, the largest Cyclades island, lies a little further and rewards the extra travel with superb sandy beaches, an atmospheric old town and castle, and green mountain villages that feel a world away from volcanic Santorini. Folegandros, small and cliff-bound, offers one of the most beautiful Choras in Greece and a slower pace still. Plan these with the Santorini to Naxos ferry and Santorini to Folegandros ferry guides.
Milos, famous for its lunar Sarakiniko beach and colourful fishing villages, and Crete, with the palace of Knossos and the harbour of Heraklion, both sit within ferry reach but demand a long day and a firm eye on the return sailing. Study the Santorini to Milos ferry and Santorini to Crete ferry timetables before you book, and treat these as trips for travellers with a spare, flexible day.
Each ferry island rewards a different appetite. Ios draws beach-lovers and night owls, Naxos draws walkers and food lovers, and Folegandros draws those chasing quiet. The choice comes down to how far you are willing to travel and how long you want on land. A closer island means more hours ashore; a distant one means a longer, more adventurous crossing. Weigh the ferry hours against the reward before you commit your day.
Which day trip is best for families and couples?
The volcano and hot springs boat suits families best, thanks to the hike, the swim and the active pace children love. A sunset catamaran cruise suits couples best, with its relaxed sailing, onboard meal and caldera sunset over the water.
Families gravitate to the volcano trip. The short crater hike gives children a real adventure on strange black ground, the warm-springs swim turns them ochre-tinged and delighted, and the boat itself keeps young travellers occupied throughout. The group boats are inexpensive and forgiving of short attention spans, and the whole outing fits into a half day, leaving time for a beach afternoon. Pair it with a stop at Akrotiri for a dose of buried-city history.
Older children and teenagers enjoy the catamaran too, thanks to the snorkelling stops and the swim platform. Younger families favour the shorter group boat, which spends less time under sail and more time at the two volcanic islets. Either way, the caldera trips beat the crowded clifftop paths for a day with children, and they give parents a rest from the steep steps of Fira and Oia.
Couples lean towards the catamaran. The smaller group, the sailing pace, the swimming stops in quiet coves and the meal served on deck make it romantic in a way the crowded terraces of Oia rarely match. Timing the sail so the sun sets over the caldera from the water is the highlight of countless honeymoons. The trip dovetails with a wider Santorini honeymoon and an evening tasting at the island’s wineries.
How long does each day trip take?
The volcano boat runs a couple of hours, the catamaran cruise fills most of a day, and Thirassia works as a half day. Ferry trips to Ios or Naxos take a full day door to door once you count both crossings and time ashore.
Trip length shapes the rest of your day, so match it to your plans. The basic volcano and hot springs boat is a compact half-day outing, leaving the morning or afternoon free. The catamaran cruise stretches longer, filling most of the daylight hours with sailing, swimming and a meal, and the sunset version runs into the evening. Thirassia sits comfortably as a half day if the ferry times align, or as a lunch stop on a longer cruise.
Ferry island trips consume the whole day. Between the outbound crossing, the hours ashore and the return sailing, a day trip to Ios or Naxos is a full commitment, and the more distant islands of Folegandros, Milos and Crete leave only a short window on land. The table below lays out the character of each option so you can see at a glance which trip fits your day and your travelling group.
Which Santorini day trip suits you?
The volcano boat suits active families, the catamaran suits couples wanting comfort, Thirassia suits those craving quiet, and the ferry islands suit travellers with spare days. Match the trip type to your group and your schedule for the best day out.
The attributes below compare each Santorini day trip so you can pick with confidence.
| Destination | Trip type | Highlight | Who it suits |
|---|---|---|---|
| Nea Kameni volcano | Caldera boat | Crater hike and steaming vents | Active families |
| Palea Kameni | Caldera boat | Warm ochre hot springs swim | Families, first-timers |

| Naxos | Fast ferry | Sandy beaches and mountain villages | Explorers with spare time |
| Folegandros | Fast ferry | Clifftop Chora and slow pace | Quiet seekers |
| Milos or Crete | Fast ferry | Lunar beaches or Minoan history | Travellers with a full spare day |
Can you do a day trip to a nearby island and back?
You can do a day trip to a nearby island and return the same day, most reliably to Ios or Naxos, provided you check both the outbound and return ferry times. Limited sailings make the return crossing the part that decides whether the day works.
Same-day island returns work best for the closest islands. Ios is the safest choice, with a short crossing that leaves a full day ashore and an evening ferry back to Santorini. Naxos works too, though the longer crossing trims your time on the island and demands a sharper eye on the timetable. Both give a genuine taste of a second island without the cost or hassle of moving your luggage.
The distant islands are riskier as same-day returns. Folegandros, Milos and Crete each involve long crossings, and a single missed or cancelled ferry can strand you overnight. Book the ferry ahead in high season, note the exact return time, and build in a buffer so a late boat ashore does not cost you the crossing home. Plan the logistics with how to get to Santorini and the island’s cruise port guide.
Do you need to book day trips ahead?
You need to book boat cruises and catamaran sails ahead in summer, since the smaller trips sell out fast from early summer through early autumn. Ferry day trips need a reserved seat in peak season, and both benefit from booking well before you travel.
Advance booking protects the trips that matter most. The sunset catamaran and the smaller-group volcano cruises fill early in the high season, and turning up on the day rarely secures a place. Reserve these as soon as your dates are firm, ideally before you arrive on the island, to lock in the sailing you want rather than settling for whatever remains.
Ferry seats also warrant early booking in the peak months, when popular sailings to Ios and Naxos sell out and deck space fills. Reserve the return leg at the same time, because that crossing is the one that gets you home. A booked seat also spares you the scramble at the port, where standby queues form early on busy mornings. Off-season, when crowds thin, you gain more flexibility to book a day or two ahead, though the ferry timetable itself also thins, so the return sailing still needs checking against the guide to the best time to visit Santorini.
When is the best time of year for day trips?
The best time of year for Santorini day trips runs from late spring through early autumn, when seas stay calm, ferries run often and the boat cruises operate daily. High summer brings the warmest swimming but the biggest crowds and the strongest afternoon winds.
Day-trip season follows the sailing weather. Late spring and early summer bring warm, settled seas, reliable ferry schedules and boat cruises that run every day, all without the crush of peak August. This shoulder window gives the smoothest crossings and the easiest booking, and it is the sweet spot for both the caldera boats and the island ferries.
High summer delivers the warmest water for the hot-springs swim and the longest daylight, but it also brings the heaviest crowds, the priciest boats and the strong afternoon meltemi wind that can chop up the sea and occasionally cancel a sailing. Early autumn returns calmer conditions and thinner crowds, an underrated time for day trips. Weigh the trade-offs against the guide to the best time to visit Santorini before you lock in your dates.
How do you plan a Santorini day trip?
You plan a day trip by booking boat cruises ahead in summer, checking ferry times in both directions for island trips, and considering a guided private land tour to cover four or five sights in a day. The caldera cruise is the standout starting point.
A little planning makes day trips smooth and rewarding. For the boat excursions, the caldera, volcano and sunset cruises, book ahead through the summer, especially for the smaller catamaran and sunset trips that sell out. Decide early whether you want the budget group boat or the roomier catamaran, since they run on different schedules and fill at different rates.
For island day trips to Ios, Naxos or Thirassia, the crucial step is checking the ferry timetable in both directions, since limited sailings can make or break the day. On land, a guided private tour is an efficient way to combine four of the island’s own highlights, such as Akrotiri, a winery, the villages and a beach, in a single day with a driver and local insight, set out alongside the guides to Santorini private tours and a Santorini itinerary. The questions below cover the points travellers ask most.
Frequently Asked Questions
What is the best day trip from Santorini?
The best day trip is a caldera boat cruise to the active volcano of Nea Kameni and the warm hot springs, often combined with the island of Thirassia and a sunset over Oia. It is the classic Santorini excursion, available as budget group boats or relaxed catamaran cruises.
Can you take a day trip to another island from Santorini?
You can day trip by fast ferry to nearby Cyclades islands, most easily Ios, the closest island, and Naxos a little further on, as well as the quiet sister island of Thirassia just across the caldera. Check the return ferry times carefully to make the day work.
How long is the Santorini volcano day trip?
The basic Santorini volcano and hot springs boat trip runs a couple of hours, with a hike up Nea Kameni’s craters and a swim in the warm springs at Palea Kameni. Longer catamaran cruises that add Thirassia or the sunset fill most of the day instead.
Do you need to book Santorini day trips in advance?
