€33.00 on Tuesday 22 September 2026: that is the cheapest crossing ahead in our readings of 22 August 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. The window covers August and September 2026.
Sète–L'Île-Rousse: what our readings show
The cheapest dates read as follows: €33.00 on Tuesday 22 September 2026, €39.00 on Wednesday 26 August 2026, €41.00 on Tuesday 8 September 2026, then €41.00 on Tuesday 15 September 2026. From the first to the last of this ranking, the gap holds within three euros.
Two departure days appear in our readings, and they do not tell the same story. Wednesday holds the lowest average, €39.00, ahead of Tuesday at €38.33. Yet it is a Tuesday that carries the lowest price of the window, and Tuesday dominates this ranking of floors: the most frequent day is not the one with the better average.
For a round trip, the best combination recorded left on Wednesday 22 September 2026 at €33.00 and came back on Monday 28 September 2026 at €39.70, for €72.70 in total, both legs with Corsica Ferries. The return leg cost less than the outward one.
September 2026 holds both the floor and the highest average
The lowest price of the window, €33.00, falls on Tuesday 22 September 2026. September 2026 is nonetheless the dearest month on average, at €38.33, while August 2026 sits below it, at €39.00 on average, with an entry price of €39.00 recorded on Wednesday 26 August 2026. The cheaper month on average is not the one that lands the best single date.
The spread stays narrow from one month to the next: from €39.00 to €38.33 between the lowest and the highest average. That reading holds for this two-month window, not for a year: October 2026 and the months that follow do not appear in our readings of 22 August 2026.
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 September 2026 departures follow one another seven days apart, from Tuesday 8 September 2026 to Tuesday 22 September 2026. A route with one departure a week leaves few dates to choose from, and the price moves all the less for it.
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. Toulon posts the lowest entry price: from €28.00 with Corsica Ferries for a departure on Friday 21 September 2026, at €40.25 on average. Savona, on the Italian side, starts at €29.30 on Tuesday 28 August 2026 (€36.02 on average) and Nice at €31.40 on Friday 15 September 2026 (€38.80 on average), again with Corsica Ferries. Marseille, run by Corsica Linea, stays apart: from €44.10 on Sunday 24 August 2026, for €61.75 on average.
Sète comes last among the Corsica Ferries ports on both readings. Its entry price, €33.00, recorded on Tuesday 22 September 2026, is the highest of the four; its average, €38.50, is the highest too. Nice (€38.80) comes within a euro of it, while Savona (€36.02) and Toulon (€40.25) sit further below. It is on the best single date that the departure port really weighs: Toulon drops well below Sète on one precise departure, while the averages stay close. Only Marseille, with Corsica Linea, breaks away from the pack (€61.75 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, stops at September 2026. As of 22 August 2026, the finding comes down to two figures: on the August and September 2026 departures, the foot-passenger crossing Sète–L'Île-Rousse never left the €33.00–€41.00 band.
