Baie de Somme South Coast Loop

This route is classified as a moderate touring bicycle ride, requiring good fitness. While much of it is paved, be prepared for some unpaved and challenging segments where you might need to push your bike. The terrain is generally gentle, but you'll encounter steeper sections as you approach the southern cliffs of the bay. A unique part of the trail is the White Route of the Bay of Somme (Route Blanche), a former road with distinctive white sand dunes.

The loop starts and ends in Le Hourdel. You can typically find parking near Hourdel Beach and Hourdel Point, which serves as a convenient starting point for the trail.

The best times to cycle this route are generally spring and autumn when the weather is mild and the natural beauty of the Baie de Somme is at its peak. Summer can also be pleasant, but be aware of potentially larger crowds, especially in popular areas like Mers-les-Bains and Le Hourdel. Always check local weather conditions before you go.

While the Baie de Somme region is generally welcoming to dogs, specific rules can vary within the Parc Naturel Régional Baie de Somme Picardie Maritime and nature reserves. It's best to keep dogs on a leash, especially in areas with wildlife, such as near seal colonies or birdwatching spots, to protect the local fauna. Always clean up after your pet.

No, you do not need special permits or to pay entrance fees to cycle this specific route through the Parc Naturel Régional Baie de Somme Picardie Maritime. However, always respect local regulations, especially concerning wildlife and protected areas.

This route offers excellent opportunities for wildlife observation. Le Hourdel is a prime spot to see a colony of nearly 300 harbor seals and 50 gray seals, particularly at low tide. The trail also passes through ornithological reserves like Marquenterre and Hable d'Ault, making it ideal for birdwatching. The entire area is a refuge of biodiversity.

You'll encounter several notable points of interest. Highlights include the Blockhaus du Hourdel, the unique White Route of the Bay of Somme, and the Ault to Cayeux-sur-Mer coastal nature reserve trail. For stunning views, look out for the View of Onival Beach and the Ault Cliffs, the Eastern end of Falaises d'Albâtre, Ault coastal panorama, and the Ault viewpoint. In Mers-les-Bains, explore the Belle Époque houses.

Yes, this route intersects with several other paths. You'll find sections that overlap with the Sentier du Littoral, the EV4 France (both Cayeux-sur-Mer - Le Crotoy and Le Tréport - Cayeux-sur-Mer segments), and the Voie Verte de la Baie de Somme. It also incorporates parts of local routes like Le Gravelot (boucle A) and the Route Blanche.

Yes, both Le Hourdel and Mers-les-Bains offer amenities. Le Hourdel, being a small fishing village, has a few local eateries. Mers-les-Bains, a larger seaside town, provides a wider selection of cafes, restaurants, and accommodation options, particularly around its beach and Belle Époque district. It's a good spot for a break or an overnight stay.

Given the moderate difficulty and potential for unpaved sections, we recommend bringing a well-maintained touring bicycle, a helmet, appropriate cycling attire, and plenty of water. Snacks are also advisable for the nearly 4-hour ride. Don't forget sun protection, a basic repair kit, and binoculars for wildlife spotting, especially for seals and birds.

While the route is moderate and mostly paved, some unpaved and challenging segments might be difficult for younger children or those less experienced on bikes. The distance of nearly 59 km is also substantial. Families with older, fit children or those comfortable with longer rides might enjoy it, but consider the full duration and potential need to push bikes in certain areas.
