Fort-Mahon-Plage and Quend-Plage are not strictly part of the Baie de Somme, but they complement a stay in the northern part of the Picardy coastline very well. People come here for a large beach, a long walk along the beach, the dunes, and an opening towards the Baie d’Authie.
If you are staying near Le Crotoy, Rue, Saint-Quentin-en-Tourmont, or the Marquenterre, this outing allows you to reach a large beach without going too far. Fort-Mahon is livelier, Quend often calmer, and the beach allows you to connect the two depending on the tide, the weather, and the distance you want to walk.
Information checked in June 2026: Access, parking, surveillance hours, rules for dogs, and beach conditions may change depending on the season. Also check parking in Fort-Mahon-Plage before arriving in high season. Before a long walk or an outing near Baie d’Authie, check the tides and official information.
Why go to Fort-Mahon or Quend during a stay in the Baie de Somme?
The Baie de Somme mainly offers estuary landscapes, ports, mudflats, and sandbanks. Fort-Mahon and Quend offer something different: a wider beach, a more traditional seafront, dunes, seaside resort activities, and an easy walk when you just want to get some fresh air.
It’s a good idea if you have already visited Saint-Valery-sur-Somme, Le Crotoy, or Le Hourdel, or if you are looking for a more beach-oriented outing. From the north of the bay, it is easy to include this outing in a day around Marquenterre, Rue or Quend.

Fort-Mahon-Plage: the liveliest outing
Fort-Mahon-Plage is the simplest option if you want a seaside location, beach, shops, seasonal activities, and direct access to the sand. It is also a good starting point if you want to walk to Quend-Plage along the beach, provided you plan for the return.
The resort is well suited for a half-day of relaxation between the beach, a walk, and a terrace break. You can walk on the beach, watch the sand yachts if there are any, have a break on the avenue de la Plage, then head back towards the dunes or towards Quend depending on the time available.
Quend-Plage: calmer, more stretched out
Quend-Plage-les-Pins is often quieter than Fort-Mahon. The main appeal comes from the beach, the dunes, and the sense of space. If you are looking for less activity and more tranquility, Quend is often the most pleasant choice.
The Fort-Mahon – Quend connection along the beach is easy in principle, but it depends on the tide, the wind, and your desire to make the journey in the opposite direction. On soft sand, a short distance on the map can require more effort than a walk on a path.
Walking between Fort-Mahon and Quend along the beach
Walking between Fort-Mahon and Quend is the simplest idea to enjoy the area. In clear weather, the route is easy to follow: you follow the beach, keep the dunes to your right or left depending on the direction, and you can easily adjust the distance covered depending on your desire or the time available.
The right approach is to check the tide before leaving. At low tide, the beach provides more space and walking can be more pleasant on the firm sand. At high tide, the space gradually decreases and walking can become less comfortable. For a first time, avoid leaving too late if you need to return on foot.
With children, keep a short goal: move a little along the beach, turn back before fatigue, then take a break at the station. If you want a more organized loop, the Dune du Royon trail is better suited than a makeshift out-and-back on the sand.
The Dune du Royon trail
The Dune du Royon trail is an interesting option between Fort-Mahon-Plage and Quend-Plage. The official guides present it as a short loop, around 4 to 4.5 km depending on the source, with a route through dunes, pine forest, and passing close to Quend-Plage and Belle Dune.
It’s a good option if you want something other than just walking on sand. The terrain remains accessible, but you should wear appropriate shoes, especially after rain or if the sand is dry and deep in places.
What else to do around Fort-Mahon?
If the beach is not enough to occupy the day, the Fort-Mahon area also offers several activities that are easy to include during a stay. They do not replace a walk on the sand, but they can help to compose a more complete day, especially with children or if the weather limits swimming.
Golf de Belle Dune Worth considering if you want a more relaxed activity, on a course known in the area. Check the slots, rates, and access conditions before booking.
Aquaclub de Belle Dune Useful for a pool break, especially with children. Opening hours and periods may vary according to the season.
Horse riding and sliding activities The L’Étrier riding center and Eolia offer activities depending on the season: horse riding, land sailing, sailing, coastal walking, or rentals. It is best to book before you go.
Baie d’Authie and seals: what you need to know
Baie d’Authie is well known for seal watching, but the most officially cited observation is mainly on the Berck side, near the mouth of the Authie, at low tide. The Berck tourist office indicates that grey seals and harbor seals are visible there all year round, when the sandbanks are exposed.
From Fort-Mahon, you should not try to cross the Baie d’Authie to reach Berck or approach the animals. Official guidelines remind that the sea creates dangerous currents in this area. Seals should be observed from a distance, without crossing the Authie, without approaching them, and with a dog kept on a leash.
If your main goal is to see seals in the Baie de Somme, also keep our guide on the Pointe du Hourdel.
With a dog, children, or a bicycle
With a dog, check the beach rules before leaving. Rules can change depending on the municipality, the season, and monitored areas. Near seals or in the dunes, keeping your dog on a leash is the right reflex to avoid disturbances and respect natural areas.
With children, Fort-Mahon is often simpler for a first outing: direct access, seafront, easy breaks, and the possibility to turn back quickly. Quend is suitable if you are looking for a calmer walk, but be sure to bring water, a windbreaker, and enough energy for the return.
By bike, the area can be part of a larger ride around Marquenterre, Quend, or Rue. For a first route in the Baie de Somme, our article on the Baie de Somme by bike gives the basic landmarks before extending towards the north.
How to fit it into a stay?
Fort-Mahon and Quend are especially convenient if you are staying north of the Baie de Somme. From Saint-Valery-sur-Somme or Cayeux-sur-Mer, the trip is still possible, but it adds more road. From Le Crotoy, Rue, or the Marquenterre, it combines more easily with a day in nature or at the beach.
For a simple day, plan Fort-Mahon in the morning, walk towards Quend if the tide allows, then a break or return by the same route. For a more nature-focused day, keep to the Sentier du Royon and Baie d’Authie. If you want to compare Bagatelle, Nausicaá or Samara, see the guide to family days out around Baie de Somme.
Parking in Fort-Mahon: plan a little leeway
In Fort-Mahon-Plage, parking is paid by meter in a large part of the area between the tourist office and the seafront. It is the most convenient if you want to arrive directly near the esplanade, but check the parking charge and arrive earlier during busy periods.
Free parking spaces exist in the streets around the tourist office. They often allow you to avoid paid parking on the seafront, if you are prepared to walk a few extra minutes.
