Halfway across, the boat paused at a low, treeless little island, where half the village seemed to have come down to the quay, then pushed on through currents that made the whole sea run like a river. That night, from a windy heath of short grass and small black sheep, I counted the lights turning on rocks far out at sea, lost count, and began again.
The short answer
Ouessant, called Ushant in English and Eusa in Breton, is a rocky island at the south-western end of the English Channel that marks the westernmost point of metropolitan France, Wikipedia records. It is at most about 8 kilometres long and 3 wide, covers some 15.6 square kilometres, rises to 61 metres, and had 860 people in 2023 by INSEE’s count, most of them in or near Lampaul, its one village. About 12 kilometres to the south-east, by this entry’s measurement, lies Molène: under a kilometre across, with 176 people in 2023, it is the largest island of the Molène archipelago, a group of about twenty islands and islets. Both are communes of Finistère, in Brittany, and both lie in the Iroise Sea, the stretch of Atlantic between Ouessant and the Île de Sein.
Why it's worth knowing
The last of France. For sailors Ouessant has long been the corner of Europe: the old shanty “Spanish Ladies” measures the run “from Ushant to Scilly” as thirty-five leagues, and the line between Ouessant and Lizard Point in Cornwall is the standard start and finish of round-the-world sailing records such as the Jules Verne Trophy, whose rules Wikipedia cites. On 23 July 1815 the captive Napoleon, aboard HMS Bellerophon on the way to his final exile, spent several hours on deck watching Ouessant, the last of France he saw, by the account of the historian David Cordingly.
A sea of lights. The waters here are some of the most dangerous in Europe, with violent winter storms and strong currents, Wikipedia records; an old Breton rhyme warns that “who sees Molène sees his pain, who sees Ouessant sees his blood”. The Fromveur, the strait between Ouessant and the Molène archipelago, often runs at about 8 knots, and its tidal currents are the second strongest in France after the Raz Blanchard in Normandy, by the 2003 study Wikipedia cites. So the islands are ringed with lighthouses: the Stiff, built under Vauban’s orders in 1695 and one of the oldest in France still in use (French heritage and guide sources, as indexed); the Créac’h, lit in 1863; La Jument, built on a rock about 300 metres off Ouessant between 1904 and 1911; and Kéréon, on a reef in the Fromveur, built from 1907 to 1916 and the last of France’s lighthouses in the open sea to be automated, on 29 January 2004, by the culture ministry’s heritage record that Wikipedia cites.
A protected sea. UNESCO named the islands and the Iroise Sea a biosphere reserve in 1988, and in 2007 the sea became France’s first marine natural park, the Parc naturel marin d’Iroise, covering about 3,500 square kilometres (the French Biodiversity Agency, as indexed; Wikipedia gives 3,550). Wikipedia calls it the richest seaweed environment in Europe, with some 300 species, and the Molène archipelago holds what Sciences Ouest, the Espace des sciences magazine in Rennes, has called the southernmost grey-seal colony in the Atlantic. The park counts the colony’s pups every fortnight from mid-October to mid-December, by its monitoring reports as indexed.
The field notes
The Créac’h and its mercury bath
The Créac’h, near Ouessant’s western tip, is a tower painted in black and white bands, lit in 1863 and listed as a historic monument in 2011, Wikipedia records; since 1988 the site has also housed the Musée des Phares et Balises, a museum of lighthouses and beacons (guide sources, as indexed). Its great lens turns on a bath of mercury, now judged obsolete and toxic. In 2025 a plan to replace the old optics with LED lamps, which would have cut its range from about 30 nautical miles to 19 by Figaro Nautisme’s account, met a petition that the same report put at more than 27,000 signatures, from an island of about 850 people. In November 2025 the minister for the sea, Catherine Chabaud, suspended the work and promised not to touch the light without keeping its historic optics. A call for proposals ran from 22 December 2025 to 22 March 2026; in July 2026 three solutions were kept for a second phase, with a final choice expected at the end of 2026, by the French ecology ministry’s release as indexed.
Molène, the small island
Molène’s village and harbour face east, towards the mainland, opposite a small tidal islet. The island is not connected to the mainland grid: its electricity comes from diesel generators, burning more than 100,000 litres of fuel a year, and its water from rain caught in household cisterns and, since 1989, from boreholes (an EU clean-energy islands study of 2020 and the Enez Green island project’s pages, as indexed). Its population fell from 527 in 1968 to 141 in 2017 before rising to 176 in 2023, by INSEE’s figures. Wikipedia names one local speciality, Molène sausage, smoked over seaweed.
The islets you cannot land on
Three uninhabited islets of the archipelago, Trielen, Banneg and Balaneg, became the Iroise national nature reserve in 1992 for their nesting seabirds, among them storm petrels and Manx shearwaters (the 1992 decree, as indexed). A decree of 4 September 2021 extended the reserve to nearly all the uninhabited islands and islets and their foreshores, about 1,129 hectares; it leaves out Molène itself and the land of Quéménès. Under a prefectoral order of 10 March 2022, the land of the islets is closed to the public for all or part of the year, and some high foreshores are closed from 1 April to 31 July (both as indexed). Béniguet, about 60 hectares and one of France’s most important seabird breeding sites, belongs to the French Biodiversity Agency and is now inside the reserve. Quéménès, about 30 hectares, is a farm island whose tenants are chosen by the Conservatoire du littoral, which picked a new farming couple for it in 2017 from about forty applications, Figaro Nautisme reported; their plan included guest rooms. The rest are seen from the ferry or a boat trip, not walked.
The Drummond Castle, 1896
On the foggy night of 16 June 1896 the British liner Drummond Castle, bound from Cape Town for London, took the passage between Ouessant and Molène instead of the safer route north of Ouessant, struck rocks at the southern entrance of the Fromveur and sank within four minutes, by the contemporary reports in The Times that Wikipedia cites. Three people survived; 242 passengers and crew drowned. Islanders of Molène and Ouessant recovered and buried the dead, and silver medals were struck with Queen Victoria’s approval for those who helped (a medal dealer’s catalogue, as indexed). Plans for the La Jument lighthouse began soon after the wreck, Wikipedia records. On Ouessant the church’s bell tower is remembered as a gift of thanks from Victoria, the island association said in 2026 (Aleteia, as indexed).
Power from the Fromveur
Ouessant, like Molène, has no cable to the mainland grid. In 2015 a tidal turbine, Sabella’s D10, was installed in the Fromveur to supply the island; in September 2023 it provided 25 per cent of the electricity used on Ouessant, the trade site Offshore Energy reported, and since October 2024 it has been run by Inyanga Marine Energy Group under a licence to August 2028, Business Cornwall reported.
Île de Sein, to the south
The Iroise Sea’s third inhabited island, the Île de Sein, lies about 8 kilometres off the Pointe du Raz and about 40 kilometres south of Molène, by this entry’s measurement. It is flat and treeless, inside the same biosphere reserve and marine park, and reached by its own ferry from Audierne (Penn Ar Bed, as indexed). In June 1940 its men sailed for Britain to join de Gaulle’s Free French, and on 1 January 1946 the island was made a Companion of the Liberation, Wikipedia records. It is a separate trip, and this entry does not cover it.

- Board early and claim a spot by the railing before the crossing turns lively.
- On the small island, use water the way a guest would in somebody’s kitchen.
- Leave the bird islets to the birds and the seals. From the boat is quite close enough.
- Count the lighthouses at dusk and write down the total. (Three totals so far, all different. Each one retained.)
- Walk out to the westernmost rocks with your hat in your pocket, where the wind cannot borrow it.
The Créac’h lighthouse. A tower painted in black and white bands near Ouessant’s western tip, first lit in 1863 and listed as a historic monument in 2011, whose great lens still turns on a bath of mercury; a plan to replace that optic with LEDs was suspended in November 2025, and a way to keep it is being chosen in 2026. It is seen from the coast path and from the lighthouse museum at its foot, and its beam crosses the sea every night.
Tally, in the marginAll afternoon I took the striped tower for the island’s best-dressed resident. After dark its beam swept out over my head towards boats well beyond my sight, and only then, far too late for good manners, did I see it had never been dressed for my benefit.
Getting there
How to get there. By sea or by air from Brest. Penn Ar Bed passenger ferries sail to Ouessant all year from Brest, about 2 hours 30 minutes, and from Le Conquet, about 1 hour 15 minutes, with summer sailings from Camaret, about 1 hour 30 minutes; many call at Molène on the way, and a stop there costs nothing extra if you continue on a later boat (Penn Ar Bed and Finistère tourist offices, as indexed). From April to September Finist’mer also runs fast boats from Le Conquet and Lanildut to the archipelago and Ouessant, Wikipedia records. Finist’air flies a nine-seat Cessna Caravan from Brest Bretagne Airport to Ouessant in about 15 to 20 minutes, twice a day on weekdays and on Saturday mornings (the airline’s timetable page, as indexed).
When to go. May to September is the drier, calmer part of the year: Météo-France’s 1991–2020 normals for Ouessant, as Wikipedia gives them, show eight to ten rainy days a month from May to September against twelve to sixteen from November to February. Summer brings the most sailings, including Camaret’s. Seal pups are born on the archipelago’s islets from mid-October to mid-December, when the park counts them, and the islets’ nesting season runs from spring to late summer.
What to arrange ahead. A boat seat or a flight, and a bed if you are staying the night: Penn Ar Bed asks passengers to be at the quay 45 minutes before departure, an hour in school holidays. Crossings can be cancelled in bad weather, so keep a spare day at either end. The islets of the nature reserve cannot be landed on for all or part of the year; plan to see them from the water. Ouessant’s church in Lampaul, Saint-Pol-Aurélien, was closed on 30 April 2026 for roof repairs with no reopening date, Aleteia reported.
Safety. The State Department has France at Level 2, exercise increased caution, because of terrorism and unrest (advisory dated 28 May 2025 in its feed, read 5 October 2026); its text names crowded places and protests in Paris and other cities, and no area of Brittany. The hazards here are the sea’s: strong currents and fast-changing weather. Keep to the coast paths near cliff edges, and do not swim off rocks or in the channels.

Common questions
Where are Ouessant and Molène?
Ouessant and Molène are islands off the western tip of Brittany, in the Iroise Sea, in the French department of Finistère. Ouessant, about 20 kilometres offshore by this entry’s measurement, marks the westernmost point of metropolitan France; Molène lies about 12 kilometres to its south-east.
Is Ouessant the same as Ushant?
Yes. Ushant is the English name for Ouessant, and Eusa is its Breton name. Wikipedia notes it is the only place in Brittany, apart from Brittany itself, with a separate English name.
How do you get to Ouessant and Molène?
Penn Ar Bed ferries sail to Ouessant all year from Brest, about 2 hours 30 minutes, and from Le Conquet, about 1 hour 15 minutes, many stopping at Molène; summer boats also leave from Camaret. Finist’air flies from Brest Bretagne Airport to Ouessant in about 15 to 20 minutes.
Can you visit the other islands of the Molène archipelago?
Mostly from the water. The uninhabited islets are in the Iroise national nature reserve, extended in 2021, and a prefectoral order of 10 March 2022 closes their land to the public for all or part of the year. Molène is open to visitors; Quéménès is a farm island whose tenants are chosen by the Conservatoire du littoral.
Why was the Créac’h lighthouse in the news?
A plan to replace the Créac’h lighthouse’s historic optics on Ouessant with LEDs drew a petition of more than 27,000 signatures in 2025. The minister for the sea suspended it in November 2025; in July 2026 three ways of replacing its mercury bath were kept for further study.
What happened to the Drummond Castle?
The British liner Drummond Castle struck rocks between Ouessant and Molène in fog on 16 June 1896 and sank within four minutes; 242 people drowned and three survived. Islanders of Molène and Ouessant recovered and buried the dead, and Britain struck medals for those who helped.
Are there seals around Ouessant and Molène?
Yes. Grey seals live and breed among the islets of the Molène archipelago, a colony the magazine Sciences Ouest has called the southernmost in the Atlantic. The Iroise marine park counts the pups every fortnight between mid-October and mid-December.
Is it safe to visit Ouessant?
The State Department rates France Level 2, exercise increased caution, for terrorism and unrest (advisory of 28 May 2025), naming crowded places and protests in Paris and other cities, not Brittany. On Ouessant the main hazards are strong currents, cliffs and changeable weather.
