€40.00 on Tuesday 15 September 2026: that is the cheapest crossing ahead in our readings of 14 September 2026 on Sète–L'Île-Rousse, for an adult foot passenger in a reclining seat, with Corsica Ferries — the only company observed on the route. For now our readings cover this single foot-passenger profile, and the window is limited to September 2026.
Sète–L'Île-Rousse: what our readings show
The cheapest dates read as follows: €40.00 on Tuesday 15 September 2026, then €41.00 on Tuesday 22 September 2026. The two departures recorded fall on the same weekday and in the same month, and the price ranking runs against the calendar: the latest departure is the cheapest, the nearest one the dearest.
A single departure day appears in our readings, Tuesday, whose average, €40.50, is the same figure as the month's. No other weekday carries a recorded departure on this route, which leaves nothing to compare between days: here the price turns on the exact date, not on the day chosen.
For a round trip, the best combination recorded leaves on 15 September 2026 at €40.00 and comes back on 28 September 2026 at €36.00, for €76.00 in total, both legs with Corsica Ferries. The return leg costs slightly more than the outward one, and it does not fall on the same weekday.
September 2026, the only month recorded
The lowest price of the window, €40.00, falls on 15 September 2026, and the monthly average settles at €40.50. September 2026 is the only month recorded on Sète–L'Île-Rousse: it therefore carries both the lowest and the highest average of the window, and no month-to-month comparison is possible here. The months that follow do not appear in our readings of 14 September 2026.
Across all dates, the company comes out at €40.50 on average, for a floor of €40.00. On a route with one month and one departure day recorded, the monthly average, the day average and the company average are one and the same figure — the only case where those three readings coincide, and it says nothing beyond the line's timetable.
An overnight crossing, one departure a week
Corsica Ferries describes an overnight crossing of about fourteen hours, with a late-afternoon departure and an arrival around 08:00 the next morning. The company advertises one departure a week from April to September. On foot, boarding opens half an hour before departure, against an hour with a vehicle.
That weekly cadence shows in our readings: the departures follow one another seven days apart, from 22 September 2026 to 15 September 2026. A route with one departure a week leaves few dates to choose from, and the price moves all the less from one to the next.
Again according to the company, the port of Sète is reached from Occitanie and Nouvelle-Aquitaine; it is the westernmost of the ports our readings cover towards L'Île-Rousse.
Leaving from another port for L'Île-Rousse
Other ports serve L'Île-Rousse in our readings. Savona, on the Italian side, posts the lowest entry price: from €34.80 with Corsica Ferries for a departure on 17 September 2026, at €37.60 on average. Toulon follows at €36.30 on 10 October 2026 (€41.38 on average) and Nice at €37.00 on 3 October 2026 (€40.00 on average), again with Corsica Ferries. Marseille, run by Corsica Linea, stays apart: from €54.10 on 23 September 2026, for €60.43 on average.
On the entry price, Sète ties with Toulon among the Corsica Ferries ports: €40.00, recorded on 15 September 2026, behind Savona and ahead of Nice, whose floor is the highest of the four. On the average the order changes — Nice holds the lowest average (€40.00), closely followed by Sète (€40.50), then Savona (€37.60) and Toulon (€41.38): the port with the highest floor is also the one with the lowest average, and Sète, tied for second-to-last place at the floor, climbs to second rank as soon as the everyday price is read. Only Marseille breaks clearly away, at €60.43 on average. Leaving from Sète, the crossing is never the cheapest, but it is never expensive either.
What these readings cover
The observed profile is limited to an adult foot passenger in a reclining seat; compositions with a vehicle and cabins are not recorded to date on this route. The window, for its part, narrows to September 2026. As of 14 September 2026, the finding comes down to two figures: on the departures recorded, the foot-passenger crossing Sète–L'Île-Rousse does not leave the €40.00–€41.00 band.
