The medieval old town
Located in the estuary of the Somme, it offers in addition to its historical interest, the opportunity to walk through its streets, admiring its old stones and, during the right season, to take advantage of the many flowers that grow in the area: sensitives, hollyhocks, etc.

This botanical garden will be of interest for the simply curious person to the connoisseur. In this restricted space of Saint Valéry sur Somme of 1700 m², over a thousand species are present and labeled.

Visitors, you will leave undeniably serene from this truly original garden.

The district Courtgain
The area where fishermen live has changed little since its foundation in the 16th century is called the "Courtgain" because fishermen earn most often just enough to survive. Their houses are built without comfort hillside along narrow alleys. The single room on the ground floor served as a place of life, two small rooms upstairs to house children, often many. No running water, no electricity, much less sewer filtration: buckets were discharged into streams in the middle of the street. Life was spent in the street where the fishermen used to mend their nets on the doorstep.

The Seals

A colony of harbor seals took up residence in the Bay of Somme.

This mischievous and fearful animal points its nose at high tide in marinas and relies on the sandbanks at low tide (Hourdel beach in particular).

Where to watch the seals?
At high tide: the ports along the coast, seals are visible two hours before high tide and 2 hours after.
At low tide: along the "white road" between the Hourdel and Cayeux-sur-mer

Seals are on sandbars along the channel of the Somme between high tide plus 4 hours and low tide plus 2 hours.
- In Crotoy in the harbor and facing the basin hunts
- In Saint Valéry Sur Somme along wharf Jeanne d'Arc and the lock
- At Cap Hornu, across from the parking
- In Hourdel at the forefront of rollers
- A Canyeux-sur-Mer, along the coast

Observe them from a distance with binoculars and do not come within 300 meters, not to frighten them. If they are scared, they might abandon their young!

The presence of seals since the first half of the nineteenth century.
