Frequently asked questions
How rough is the Bay of Biscay on Iona?
+
In the October to December window her Canaries itineraries use, Biscay is at its seasonal worst and a lively crossing day is normal. Iona's 184,089 gross tons and stabilisers take the edge off roll, but they cannot flatten Atlantic swell that has the whole bay to build.
When does Iona cross the Bay of Biscay?
+
On the way to and from Iberia and the Canary Islands: the verified 2026 departures leave Southampton on October 3, November 21 and December 5, putting the crossing on roughly days 1 to 2 and 13 to 14 of each trip.
Can you avoid the Biscay crossing on an Iona Canaries cruise?
+
Not on a Southampton round trip; the bay is the road south. What you can control is timing within the itinerary, planning quiet activities for the two crossing days, and cabin position, which matters more on this route than almost any other Iona sails.
