Le Tréport / Cayeux-sur-mer

After enjoying a last look at Mers-les-Bains's cliffs and Belle Epoque villas, the Vélomaritime leads you away from the coast to Bourseville. Do stray off the cycle route if you wish to stop at Le Bois de Cise or Ault, resorts that recall the Art Deco period and its fashion for sea-bathing. Up to Cayeux-sur-Mer, you then cycle through the Hable d'Ault, a long-established lagoon protected from the sea by a pebble bank and today a haven for many species of birds.

The route

At Tréport, the port locks are crossed on foot, then you cycle along the colorful seafront of Mers-les-Bains. Be careful of the steep slope when leaving Mers-les-Bains. The route continues on cycle paths, some of which are shared with agricultural machinery. Be careful on the descent out of Ault. Finally, in the Hâble, a few hundred meters will be on a stabilized path.
