FROM MONT PELE TO MONT HULIN
Mont Pelé and Mont Hulin are hills composed of chalk and marl, which have been quarried by the cement factories at the bottom. These days, nature has again claimed this limestone slope, a vantage point over the Boulonnais area as far as the sea.

DUNES D'ECAULT
Developed by the National Forestry Office, the Bécasse footpath leads you along cliffs and windswept dunes, and then through headily scented poplars and pines. You first walk along the banks of the Warenne stream, before climbing to the top of a dune from where you can see the old Becque estuary. The Côte d'Opale presents itself to you in all its colours.

DUNES AND ESTUARIES OF THE SLACK
As the river water accumulated in the valley and formed a sort of lake, it gave the name “Slack” (a contraction of the French “ce lac”) to this little river, which today flows out into the Channel at Ambleteuse. You can follow the sign-posted circuit through pine forests, thickets of sea-buckthorn and white dunes. When it’s sunny, it’s even more beautiful – you’ll fall for the lovely “OPAL” colour.

POINTE DE LA CRECHE
The whole coast unfurls before you as far as the Cap Gris-Nez. The Pointe de la Crèche is the extremity of a cliff which stretches between Boulogne and Wimereux. Along the edge of the footpath, there are old German fortifications – in ruins or destroyed at the beginning of the 80s to give the site back its natural appearance . On the cliff, the grass gets covered with a host of little flowers: the little white campion is so lovely at the end of spring.  Amongst the birds which nest in the crevices in the walls, the fulmar petrel is certainly the best-known.

THE FLAQUE A RANES FOOTPATH
You will just love the typical Boulonnais farmland that you cross here. Wells hidden in the leaves, a barn, a pond bordered by old ash trees, gates and hedges, hornbeams pruned to a “tadpole” shape, the forest of Desvres. And not forgetting all the residents: thrushes and robins in the hedges, pheasants and snipes on the edge of the wood, jays in the oaks, deer tracks to follow, and not forgetting the bats at dusk.
