Phare du Crotoy

Phare du Crotoy is a small lighthouse standing in Le Crotoy, on the northern shore of the Baie de Somme in Picardy. Unlike the towering lighthouses of France's Atlantic coast, this is a modest but essential navigation marker — one that has guided boats through the shifting, shallow waters of the bay into the port of Crotoy for well over 170 years.

Why does Crotoy have a lighthouse at all?

The Baie de Somme is famous for its vast sandbanks and mudflats, which shift constantly with the tides. Getting into the port of Crotoy safely has always demanded precise marking, since a wrong course could easily mean running aground. The first navigational light here — a fixed white beacon mounted atop a 5-meter pole — was put into service in 1851. It was a simple signpost for sailors, marking the correct route into the bay and onward to the port itself.

How has the lighthouse changed over time?

In 1931, the original wooden pole was replaced by a proper electric lighthouse — a sturdier structure, more visible from the sea. That building didn't survive the Second World War: it was destroyed during the fighting that swept across the Picardy coast, and the site stood dark until it was rebuilt in 1948. That postwar lighthouse is the one still standing today.

What does the lighthouse look like and how does it work today?

The current Phare du Crotoy stands around 11 meters tall and runs fully automated on electric power. Its signature signal is a red light with two occultations every 6 seconds, visible from up to 8 nautical miles (about 14.5 km) offshore. The lighthouse sits between rue de la Butte and rue de la Mer, facing rue Guerlain — right in the heart of Le Crotoy's old quarter, close to the waterfront and beach.

What will you see there?

The lighthouse itself is small and not open for visits inside, but the surroundings more than make up for it. From the rise nearby — which gives rue de la Butte ("hill street") its name — the view opens out over the entire Baie de Somme: sandbanks exposed by the receding tide, colorful fishing boats pulled up on the shore, and a horizon where water and sky blur together. It's one of Le Crotoy's most popular viewpoints, especially at sunset.

How do you get there?

Le Crotoy sits on the northern point of the Baie de Somme, well connected by road to Abbeville and to Saint-Valery-sur-Somme across the bay (which can also be reached by the heritage Chemin de Fer de la Baie de Somme, a vintage train that runs along the shoreline). Within the town itself, the lighthouse is a few minutes' walk from the center — just head toward the waterfront and look for the distinctive red tower rising above the rooftops.

When should you visit?

The Baie de Somme transforms with the time of day and the season. Low tide exposes kilometers of sand and glistening mud, while high tide fills the bay right up to the town's edge — checking the tide tables before a visit is essential, since they determine what you'll actually see. Spring and autumn draw birdwatchers, as the bay is an important breeding ground and stopover on migration routes, while summer brings swimming, sailing, and Le Crotoy's full seaside season.

Frequently asked questions

Can you climb to the top of the lighthouse? No, Phare du Crotoy is a small, fully automated lighthouse with no publicly accessible tower — it's a sight to view from the outside.

Why does the lighthouse flash red? The red light with two occultations every 6 seconds is its unique identifying signature, distinguishing it from the bay's other navigation markers.

Is this the same lighthouse built in 1851? Not directly — the original 1851 pole beacon was replaced in 1931 by a built electric lighthouse, which was destroyed in the Second World War and rebuilt in 1948. That postwar structure is the one standing today.

How long does a visit take? The lighthouse itself is a quick stop of a few minutes, but combined with a walk along the waterfront, the beach, and the bay's viewpoints, it's worth setting aside at least half a day for Le Crotoy.
