L'Île-Rousse–Marseille: what our readings show
On the L'Île-Rousse–Marseille route, our readings from 14 September 2026 cover departures from September to December 2026, then the start of January 2027. For a foot passenger in a reclining seat, the crossing starts from €56.01 and works out at €64.11 on average across all the dates observed. With a car and a cabin for one adult, the recorded floor is €135.60 for an average of €191.20. Two adults with a car and a cabin start from €178.61 for €239.55 on average, and a family of two adults and two children, in the same configuration, from €242.63 for €307.53.
A single company on the route
Every crossing observed between L'Île-Rousse and Marseille is sold by Corsica Linea, on the four profiles tracked as on the whole set of dates recorded. There is therefore no comparison between companies and no codeshare gap to read here: the price turns on the departure date and on the formula chosen.
September 2026 at the peak, December 2026 at the floor
For a foot passenger in a reclining seat, September 2026 opens the window at the peak, at €81.15 on average for a minimum of €65.01. October 2026 comes back to €65.58, November 2026 to €59.46, down to the December 2026 trough, at €58.72 on average for a minimum of €56.01. January 2027, which closes the window, edges back up slightly to €60.76. The gap widens with a vehicle: for one adult with a car and a cabin, the average reaches €280.17 in September 2026 against €161.39 in December 2026; for two adults, €336.75 against €206.54; for two adults and two children, €409.06 against €272.56. On these three profiles, November 2026 holds at December's level — €161.60, €207.34 and €273.90 on average — and January 2027 climbs back to €171.35, €218.11 and €285.63.
A stable floor from September 2026 to January 2027
The foot-passenger minimum of the window, €56.01, does not sit in a single month: it is recorded as early as 17 September 2026, then again in October, November, December 2026 and once more at the start of January 2027. The same pattern holds with a vehicle: the €135.60 floor for one adult with a car and a cabin repeats from 15 October 2026 to 2 January 2027, while September 2026 never drops below €201.60 on this package. What changes from one month to the next is therefore not the entry fare, it is the average: €280.17 in September 2026 against €161.39 in December for one adult with a car and a cabin.
Thursday, cheapest all week
Only Tuesday, Thursday and Saturday carry recorded departures on this route. Thursday is the cheapest for a foot passenger in a reclining seat, at €58.66 on average; Tuesday, at €67.57, and Tuesday, at €67.57, sit within a few cents of each other. With a car and a cabin for one adult, Thursday keeps the lead at €157.54, but the other two days pull clearly apart: Saturday moves to second at €191.78, and Tuesday brings up the rear at €226.35. For two adults, the same order holds: €201.79 on Thursday, €240.90 on Saturday and €278.24 on Tuesday; for two adults and two children, €265.22 against €309.28, with €350.63 at the top. Thursday opens the ranking on all four profiles tracked; Tuesday and Saturday, almost level on foot, part ways as soon as a car and a cabin enter the basket.
The cheapest dates
The eight cheapest dates for a foot passenger in a reclining seat are all operated by Corsica Linea and all stand at €56.01: Thursday 31 December 2026, Thursday 10 December 2026, Saturday 5 December 2026, Thursday 8 October 2026, Thursday 26 November 2026, Thursday 29 October 2026, Thursday 19 November 2026 and Saturday 9 January 2027.
With a vehicle, the entry fare is just as steady: €135.60 for one adult with a car and a cabin on Saturday 14 November 2026, Tuesday 3 November 2026, Saturday 5 December 2026, Thursday 8 October 2026, Saturday 2 January 2027, Thursday 7 January 2027, Tuesday 15 December 2026 and Thursday 26 November 2026. For two adults, the eight best dates all stand at €178.61 — among them Thursday 5 November 2026, Saturday 14 November 2026 and Tuesday 3 November 2026; for two adults and two children, at €242.63, with Thursday 3 December 2026, Saturday 14 November 2026 and Tuesday 15 December 2026.
On the foot-passenger profile, the best return trip recorded pairs a departure on 6 October 2026 at €56.01 with a return on 7 October 2026 at €55.10, that is €104.11 for both legs, with Corsica Linea end to end.
Leaving from another port for Marseille
L'Île-Rousse is not the cheapest starting point for Marseille. From Porto-Vecchio, the crossing starts from €36.95 for a departure on 27 November 2026, with La Méridionale, and works out at €46.29 on average. From Ajaccio, also with La Méridionale, it starts from €37.62 for a departure on 31 December 2026 and €55.76 on average. From Bastia, the fare drops to €56.01 for €64.11 on average. From L'Île-Rousse, the floor is €56.01 for €64.11 on average with Corsica Linea. Propriano closes the list, from €57.64 for €62.60 on average. The two ports served by La Méridionale take the top two places, minimum and average alike — but swap order between themselves: Porto-Vecchio holds the lowest floor, Ajaccio the lowest average. Bastia and L'Île-Rousse, for their part, keep the same order on both readings.
