A single company on the route
Corsica Ferries carries every Nice–L'Île-Rousse departure in our readings of 22 August 2026. For an adult foot passenger in a reclining seat, the fare starts at €29.30 and comes out at €36.02 on average. With a car and a cabin, one adult drops to €102.00 at the lowest, for €134.22 on average. The minimum and the average are not read together: one is an observed floor, the other the average of every crossing recorded. According to Corsica Ferries, the crossing runs by day, in 4 hours 15 minutes to 6 hours 30 minutes, with boarding announced 30 minutes before departure on foot and one hour with a vehicle.
The floor in September 2026, the peak in October 2026
For the foot passenger in a reclining seat, the lowest average of the window belongs to September 2026, €34.73, along with the floor of the window, €32.60, recorded on 17 September 2026. The dearest month on average is October 2026, €36.85, never dropping below €29.30, recorded on 28 August 2026. October 2026 sits between the two at €36.85 on average, with a floor of €35.70 on 3 October 2026.
With a car and a cabin, the order flips: the cheapest month on average becomes August 2026. One adult pays €128.50 on average there (from €116.00 on 24 October 2026), against €145.67 in September 2026 (from €130.00) and €145.67 in August 2026, the dearest on average yet the month that carries the floor of the window, €102.00 on 28 August 2026. For two adults the ranking is the same: October at €156.50 (from €144.00), September at €175.00 (from €162.00) and August at €158.75, whose floor falls to €133.00. For two adults and two children, October carries both: the lowest average, €199.50, and the floor of the window, €186.00 on 24 October 2026, ahead of September at €221.67 (from €212.00) and August at €213.25 (from €176.00).
Friday on foot, Friday with a vehicle
For the foot passenger in a reclining seat, Friday is the cheapest day on average, €31.45, ahead of Thursday at €31.80 and Tuesday at €38.00. Saturday climbs back to €39.92 and Saturday closes the ranking at €39.92, the dearest of the days recorded. Neither Wednesday nor Sunday appears in our readings on this route.
With a car and a cabin, Friday takes the front of all three packages: €122.00 on average for one adult, €152.00 for two, €205.00 for two adults and two children. Tuesday follows everywhere, at €149.00, €181.00 and €227.00. Behind that the order scatters: for one and two adults, Friday (€122.00 and €152.00) comes in ahead of Thursday (€138.50 and €164.00), while the family of four swaps the two, Thursday at €205.00 and Friday at €216.00. Tuesday closes all three rankings, at €149.00, €181.00 and €227.00.
The cheapest dates
For the foot passenger in a reclining seat, the eight cheapest departures recorded spread across the three months of the window, all with Corsica Ferries. Friday 28 August 2026 opens at €29.30, ahead of Thursday 27 August 2026 at €31.00, Thursday 17 September 2026 at €32.60 and Friday 4 September 2026 at €33.60. Then come Saturday 3 October 2026 at €35.70, Tuesday 25 August 2026 at €38.00 and Saturday 5 September 2026 at €38.00; Saturday 24 October 2026 closes the list at €38.00. Four of these eight dates fall in August 2026, the month whose average is nonetheless the highest of the window.
With a car and a cabin, the floor changes date depending on the package. For one and two adults it falls on Friday 28 August 2026: €102.00 and €133.00. For two adults and two children, it is Thursday 27 August 2026 that opens the list, at €176.00. Thursday 27 August 2026 holds second place on all three — €112.00, €136.00 and €186.00 — while Saturday 5 September 2026, third for the family of four at €212.00, only reaches fourth place for one and two adults (€130.00 and €162.00). The date that carries the foot passenger's floor, 28 August 2026, closes the list of eight for two adults and two children, at €234.00.
As a foot-passenger return trip, our readings give an outward leg on 28 August 2026 at €29.30 and a return on 6 September 2026 at €33.00, Corsica Ferries in both directions, that is €62.30 for the two legs.
Leaving from another port for L'Île-Rousse
Ranked by minimum for the foot passenger in a reclining seat, Toulon opens the lowest, from €28.00 via Corsica Ferries for a departure on 21 September 2026, ahead of Savona at €31.40, Nice at €29.30 and Sète at €33.00, all with Corsica Ferries; Marseille, served by Corsica Linea, starts at €44.10. On average, the ranking does not move: Toulon (€40.25), Savona (€38.80), Nice (€36.02) and Sète (€38.50) sit within a few euros of one another, with Marseille apart at €61.75. Here the port cheapest at the minimum is also the cheapest on average, and the gap between the four Corsica Ferries ports plays out on the date chosen rather than on the quay of departure.
