How long is the boat crossing from Rethymno?

Expect about 2–3 hours each way by catamaran depending on sea conditions and the vessel’s speed.

Meals are not typically included; you’ll have free time in Fira and Oia to buy food at cafes and tavernas.

Is the tour wheelchair accessible?

The cruise and some transfers are accessible, but Oia and Fira have many stairs and narrow alleys—mobility access on the island is limited.

Will we see the volcano or hot springs?

You’ll view the caldera and volcanic islets from the rim; direct landings on Nea Kameni (volcanic islet) usually require a different boat excursion and extra time.

Santorini Day Trip by Catamaran from Rethymno — Oia & Fira Caldera Experience

The catamaran slips out of Rethymno at first light, the Cretan coast shrinking behind you while the Aegean opens like a bright, mobile horizon. Salt and wind press at your face; after a two-hour crossing Santorini’s black cliffs appear—sheer walls scored by ancient eruptions, crowned with white cubes of houses clinging to the rim.
