From Mont Pelé to Mont Hulin
These two mounts form a hillside of chalk and marl which have dug out by ciment works. Today Nature has retaliated over this chalky and limestone coast thus permitting vistas of the Boulonnais right down to the sea.

Dunes at Ecault
The "Bécasse" trail, which is managed by the National Forestry Office, will take you past cliffs and dunes, amongst poplar and pine trees, along the edge of the Warenne stream before climbing to the summet of a dune from which you can catch a glimps of the Becque estuary. A magnificent view of the Côte d'Opale.

Dunes and estuary of the river Slack
The waters of the river gather together in the valley to form a kind of lake (lac) from where the name of the river, Slack, originates. This river now flows down into the Channel at the seaside resort of Ambleteuse. By following the signposts the trail passes through pine trees, thickets and white sand dunes. Here the surroundings are at their best in the sunshine when the colour of opale is so apparent

The Point of the "Crèche"
This Point is at the extemity of a cliff that juts out between Boulogne and Wimereux from where you can see right up to the Gris-Nez. Along the trail are German fortifications in ruin or that were destroyed in the 1980's so that the natural environment is not too spoilt. On the cliff top the grass is covered with a multitude of flowers especially in Springtime. It is also the nesting place for many birds like the striking petrels.

"Flaque à Rânes" Trail
You will just love the Boulonnais countryside here. Wells hidden under the foliage, barns, old oak trees that surround small lakes, hedges and fences and the Desvres forest. Other wildlife also abound here : thrush and robins in the hedges, pheasants and woodcocks on the edge of the forest, from time to time roe deer and bats that flutter at twilight.
