Crete is about 2 hours south of Santorini by fast ferry, and it's an entirely different world -- ancient palaces, proper cities, mountain gorges, and beaches that stretch for kilometres. A day trip is tight but doable if you focus on Heraklion and Knossos.
In this guide
Here's the honest version: Crete is the largest island in Greece and the fifth largest in the Mediterranean. You could spend two weeks there and not see it all. A day trip from Santorini gives you Heraklion and its immediate surroundings -- the archaeological museum, the Palace of Knossos, the Venetian harbour, and a good lunch. That's it. You won't see Chania, Rethymno, the Samaria Gorge, or the south coast beaches. But what you can see in a day is genuinely impressive.
How Do You Get There?
Ferries run from Santorini's Athinios port to Heraklion's port on the north coast of Crete.

Key planning point: Take the earliest fast ferry. A 07:30 or 08:00 departure gets you to Heraklion by around 10:00, giving you a full day. Book the return ferry before you go -- the last fast ferry back to Santorini is typically late afternoon or early evening.
You can also fly. Olympic Air and Sky Express operate short flights between Santorini and Heraklion (about 30 minutes), but by the time you factor in airport transfers and check-in, the ferry is usually more practical for a day trip.
What Can You Do in a Day?
The Palace of Knossos
This is the main reason to day-trip to Crete. Knossos is the largest Bronze Age archaeological site on Crete and the ceremonial centre of Minoan civilisation -- Europe's oldest advanced civilisation, dating back to around 2000 BC. The palace complex covers about 20,000 square metres and was home to an estimated 1,000 people at its peak.
The site is about 5 km south of Heraklion city centre (15 minutes by bus or taxi). Allow 1.5-2 hours for the visit. The partially reconstructed sections -- columns painted red and black, frescoes of bull-leapers, the throne room -- give you a sense of scale that Akrotiri on Santorini hints at but can't match.
If you've already visited Akrotiri, Knossos puts it in context. Akrotiri was a prosperous Minoan outpost; Knossos was the capital. The connection between the two sites, separated by 110 km of sea, is part of what makes both so remarkable.
Entry is around 20 EUR. A guided tour is worth it here -- the site is large and the significance of what you're looking at isn't always obvious without context.
Heraklion Archaeological Museum
Located in the city centre, this is one of the most important museums in Greece. It houses the finds from Knossos and other Minoan sites -- the original frescoes, the famous snake goddess figurines, the Phaistos Disc, and gold jewellery that's 3,500 years old. If you've been to Knossos, the museum brings the ruins to life.
Allow 1-2 hours. Entry is around 12 EUR, or buy a combined ticket with Knossos for a discount.
Heraklion Old Town
The city itself is worth a walk. Highlights within easy reach of the port:
- Koules Fortress -- The Venetian fortress at the entrance to the old harbour. Built in the 16th century, well-preserved, views over the port.
- Venetian Harbour -- Fishing boats, waterfront cafes, and the old arsenals (shipyards) lining the harbour wall.
- Lion Fountain (Morosini Fountain) -- In the central Lions Square, surrounded by cafes. The social heart of the old town.
- 25th of August Street -- The main pedestrian artery connecting the port to Lions Square. Venetian and Ottoman architecture, shops, and restaurants.
Lunch
Heraklion has excellent food and it's significantly cheaper than Santorini. The streets around Lions Square and the market area (1866 Street) have dozens of tavernas. Cretan cuisine is its own thing -- look for dakos (barley rusk topped with tomato and mizithra cheese), kalitsounia (small cheese pies), and lamb dishes with local herbs. Budget 15-25 EUR per person for a proper sit-down meal.
A Realistic Day-Trip Itinerary
- 07:30 -- Fast ferry from Santorini (Athinios)
- 09:30 -- Arrive Heraklion port
- 10:00 -- Taxi or bus to Knossos (15 minutes)
- 10:15-12:00 -- Explore the Palace of Knossos
- 12:15 -- Return to Heraklion city centre
- 12:30-13:30 -- Lunch near Lions Square
- 13:30-15:00 -- Heraklion Archaeological Museum
- 15:00-16:00 -- Walk the Venetian harbour, Koules Fortress, old town
- 16:30 -- Head to the port
- 17:00-18:00 -- Return ferry to Santorini (check your specific time)
This gives you a full and satisfying day without feeling impossibly rushed. You'll see the two headline sights (Knossos and the museum) and get a real feel for Heraklion as a city.
What Should You Know Before Going?
- Crete feels different from the Cyclades. It's bigger, more urban, and culturally distinct. Heraklion is a working city of 175,000 people, not a tourist village. That's part of what makes it interesting.
- Book fast ferry tickets in advance. The popular morning departures sell out in summer, especially with SeaJets.
- Knossos gets crowded by midday. Arriving at 10:00 from the morning ferry is actually good timing -- you'll be there before the tour bus crush.
- Combined tickets save money. The Knossos + Archaeological Museum combo ticket is cheaper than buying separately.
- The bus from Heraklion to Knossos runs every 20 minutes from Bus Station A (near the port). It's cheap and straightforward. A taxi is about 10-15 EUR each way.
- Don't try to visit anywhere beyond Heraklion. Rethymno is 1.5 hours west by car. Chania is 2.5 hours. The Samaria Gorge is a full-day hike on its own. None of these are realistic on a day trip from Santorini.
- Organised day tours exist and handle all the logistics -- ferry tickets, transfers, guided tours of Knossos. They're convenient but lock you into a fixed schedule. Independent travel gives you more flexibility.
When Is the Best Time to Go?
May-June and September-October -- Good weather, reliable ferry schedules, Knossos is busy but manageable.
July-August -- Hot (Heraklion can hit 35C+) and the most crowded at Knossos. Ferries run frequently but book well ahead.
April and November -- Fewer ferries. Weather is cooler, which is actually pleasant for sightseeing. Some tourist facilities may have reduced hours.
Crete is about 110 km south of Santorini. Fast ferry takes 2 hours. Tickets from around 50 EUR one way. Focus on Heraklion and Knossos for a day trip -- Crete is too big for anything more in a single day.
