A single company on the route
Corsica Ferries carries every Nice–L'Île-Rousse departure in our readings of 14 September 2026. For an adult foot passenger in a reclining seat, the fare starts at €37.00 and comes out at €40.00 on average. With a car and a cabin, one adult drops to €134.00 at the lowest, for €148.33 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 October 2026, the peak in September 2026
For the foot passenger in a reclining seat, the monthly average rises from one month to the next: €37.50 in October 2026, against €45.00 in September 2026. The minimums go the same way: €45.00 on 17 September 2026, against €37.00 on 3 October 2026. The month with the lowest average therefore also carries the best one-off price of the window, but the gap between the two floors stays far thinner than the gap between the averages.
With a car and a cabin, the reading is simpler: October 2026 wins across the board, average and floor alike. For one adult, €140.50 against €164.00 in September 2026, for a floor of €134.00 against €164.00. For two adults, the same shape: €170.50 against €202.00, a floor of €164.00 against €202.00. For two adults and two children, €215.50 against €256.00, a floor of €208.00 against €256.00. As for the foot passenger, the cheapest month on average here also carries the lowest one-off price, with a far wider gap between the two months.
Saturday on foot, Saturday with a vehicle
Only Thursday and Saturday carry recorded departures on this route. For the foot passenger in a reclining seat, Saturday comes out at €37.50 on average; Thursday closes the ranking at €45.00, the dearer of the two days recorded.
With a car and a cabin, the order flips. For one adult, Saturday holds €140.50 against €164.00 on Thursday. For two adults, the same shape: €170.50 against €202.00; for two adults and two children, €215.50 against €256.00. Saturday, the dearest on foot, becomes the cheapest with a vehicle; Thursday, the cheapest on foot, moves to the top of the prices as soon as a vehicle enters the package.
The cheapest dates
For the foot passenger in a reclining seat, the cheapest dates recorded are spread across the window's two months, all with Corsica Ferries: one in September 2026, two in October 2026. Saturday 3 October 2026 opens at €37.00, ahead of Saturday 24 October 2026 at €38.00; Thursday 17 September 2026 closes the list at €45.00.
With a car and a cabin, the two best departures are the same on all three packages, but not in the same order. For one adult as for two, Saturday 24 October 2026 carries the floor, €134.00 and €164.00, ahead of Saturday 3 October 2026 at €147.00 and €177.00. For two adults and two children, the order flips: Saturday 24 October 2026 leads at €208.00, ahead of Saturday 3 October 2026 at €223.00. The only September departure follows, last on all three packages: Thursday 17 September 2026 at €164.00, €202.00 and €256.00.
As a foot-passenger return trip, our readings give an outward leg on 17 September 2026 at €45.00 and a return on 3 October 2026 at €54.30, Corsica Ferries in both directions, that is €99.30 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 €36.30 via Corsica Ferries for a departure on 10 October 2026, ahead of Savona at €34.80, then Nice and Sète at the same entry fare, €37.00 and €40.00, all with Corsica Ferries; Marseille, served by Corsica Linea, starts at €54.10. On average, the order is reshuffled: Savona takes the lead (€37.60), ahead of Nice (€40.00) and Sète (€40.50), while Toulon, first on the floor, comes out last of the four ports served by Corsica Ferries, at €41.38 — these four averages sit within less than a euro of each other. Marseille stays apart on both readings, at €60.43 on average. The quay of departure is therefore not chosen the same way depending on whether you are after a one-off price or an everyday one.
