L'Île-Rousse–Marseille: what our readings show
On the L'Île-Rousse–Marseille route, our readings from 22 August 2026 cover departures from August 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 €70.19 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 €230.00. Two adults with a car and a cabin start from €178.61 for €282.80 on average, and a family of two adults and two children, in the same configuration, from €242.63 for €355.08.
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.
August 2026 at the peak, December 2026 at the floor
For a foot passenger in a reclining seat, August 2026 opens the window at the peak, at €126.51 on average for a minimum of €124.01. September 2026 comes back to €73.63, October 2026 to €65.44, 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 €527.93 in August 2026 against €161.39 in December 2026; for two adults, €620.44 against €206.54; for two adults and two children, €720.13 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 8 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 6 October 2026 to 9 January 2027, while August 2026 never drops below €423.60 on this package. What changes from one month to the next is therefore not the entry fare, it is the average: €267.91 in September 2026 against €161.39 in December for one adult with a car and a cabin.
Thursday rather than Sunday
Among the days present in our readings, Thursday is the cheapest for a foot passenger in a reclining seat, at €62.21 on average, ahead of Saturday at €72.82 and Tuesday at €70.23; Sunday sits markedly above, at €104.68. With a car and a cabin for one adult, Thursday keeps the lead at €177.05, but Tuesday and Saturday swap places, at €235.10 and €251.46, before Sunday at €402.27. For two adults, Sunday climbs to €479.94 against €224.31 on Thursday; for two adults and two children, to €564.63 against €292.83. Thursday opens and Sunday closes the ranking on all four profiles tracked; only the order of Tuesday and Saturday changes from one package to the next.
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 10 December 2026, Thursday 19 November 2026, Thursday 8 October 2026, Tuesday 6 October 2026, Thursday 29 October 2026, Saturday 9 January 2027, Thursday 26 November 2026 and Tuesday 3 November 2026.
With a vehicle, the entry fare is just as steady: €135.60 for one adult with a car and a cabin on Thursday 7 January 2027, Saturday 14 November 2026, Tuesday 3 November 2026, Thursday 8 October 2026, Tuesday 15 December 2026, Thursday 5 November 2026, Thursday 12 November 2026 and Thursday 3 December 2026. For two adults, the eight best dates all stand at €178.61 — among them Thursday 7 January 2027, Thursday 10 December 2026 and Thursday 15 October 2026; for two adults and two children, at €242.63, with Saturday 21 November 2026, Tuesday 6 October 2026 and Thursday 26 November 2026.
On the foot-passenger profile, the best return trip recorded pairs a departure on 8 September 2026 at €56.01 with a return on 23 September 2026 at €47.10, that is €96.11 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 €34.62 for a departure on 20 October 2026, with La Méridionale, and works out at €46.13 on average. From Ajaccio, also with La Méridionale, it starts from €36.95 for a departure on 3 January 2027 and €44.08 on average. From L'Île-Rousse, the floor is €56.01 for €70.19 on average with Corsica Linea, a level close to Bastia, which opens at €56.01 and holds €70.19 on average. Propriano closes the list, from €57.64 for €71.89 on average. The two ports served by La Méridionale take the top two places on the minimum as on the average; between L'Île-Rousse and L'Île-Rousse, by contrast, the two rankings swap.
