A boat ride from athens to santorini starts at Piraeus, Athens’s main passenger port, and runs on either a high-speed ferry that halves the crossing time or a conventional ferry that costs less but takes longer. Here’s what I’d actually do first: check which type of ferry each operator runs on your travel date before booking, since the price difference between the two is usually bigger than people expect.
I’ll cover the crossing times, typical prices, and when I’d steer you toward flying instead, then point you to the island’s other ferry routes if Athens isn’t your starting point.

A boat trip to santorini from Piraeus on a high-speed ferry typically runs a few hours, while a conventional ferry can take close to double that. The exact time depends on the operator and whether the sailing makes stops at other islands along the way.
My honest take: I’d check the specific sailing’s stop pattern before assuming “high-speed” means a direct route, since some high-speed boats still call at Paros or Naxos on the way.
How Much Does the Athens to Santorini Ferry Cost?
A boat trip from athens to santorini on the high-speed option generally costs noticeably more than the conventional ferry, with prices shifting by season, how far ahead you book, and which company you choose. Summer sailings run highest, since demand peaks exactly when most travelers want to go.
I’d book the conventional ferry if the extra few hours don’t bother you and you’d rather put that savings toward something else on the island, like one of the Santorini boat tours I’ve reviewed elsewhere on this site.

A private boat athens to santorini charter exists but is a different product entirely from a scheduled ferry, typically a much longer and more expensive undertaking given the open-water distance involved, and it is not something GetYourGuide or similar platforms sell for this specific crossing. For nearly everyone, a scheduled high-speed or conventional ferry is the practical choice for this leg.
I’d only look into a private option here if you’re chartering a multi-day sailing trip around the Cyclades rather than a simple point-to-point transfer, since the cost and time involved make it impractical for a one-way hop.
Should You Fly From Athens Instead?
A direct flight from Athens covers the same distance in a fraction of the ferry’s crossing time, so if minimizing travel time is your only concern, flying wins. I’d still pick the ferry if sailing into the caldera and seeing Santorini’s cliffs rise from the water as you approach is part of the experience you want from this trip.
My honest take: I’d fly if you’re short on vacation days or prone to seasickness, and ferry if the journey itself matters to you, not just the destination.

I’d book a summer sailing on this route at least a few weeks out, since the most popular high-speed departures fill up during peak season. Outside summer, a week or two of lead time is usually enough, though checking the schedule early still helps you lock in your preferred departure time.

For most travelers starting their trip in Athens, I’d book the high-speed ferry and treat the few hours on deck as a scenic start to the trip rather than dead time. If budget matters more than speed, the conventional ferry gets you there for less without much real downside beyond the extra hours.
If you’re coming from a different island instead, my ferry to Santorini pillar routes you to every other departure point, my Crete to Santorini ferry page covers that specific crossing if you’re island-hopping through there first, and my Mykonos and Rhodes ferry page covers onward routes if Athens is just your first stop.
