The best mountain bike trails

For life-size sensations

With 13 mountain bike trails, the Pays de Saint-Omer et de Lumbres is increasingly becoming a sporting destination. With the creation of the Lumbres mountain bike trail base, mountain bikers will find marked routes with thrills. What’s more, services, maintenance and even mountain bike rentals enhance the experience, all while reconnecting with nature. This selection allows you to get an overview of the routes while admiring landscapes, natural sites or historical sites.

Slaloming with the Aa

Les Pommiers in Fauquembergues

This 38 km route allows you to discover the Aa, our region’s emblematic coastal river, as well as its built heritage. Winding through the hills of the Aa valley, the green landscape takes us to the Bois de Renty, scene of a famous battle between the troops of Charles V and Henry II.

Discover a mysterious place

The Saint-Louis chapel in Tournehem-sur-la-Hem

Despite its relative length, this 10.2 km course is one of the most beautiful. However, to be able to admire the whole Hem valley, to catch a glimpse of the white cliffs of Dover in England is a panorama not to be missed. Passing the mysterious Saint-Louis de Guémy chapel, the course passes close to the imposing Tournehem-sur-la-Hem state forest.

The longest

The hermit in Quercamps

We’re off on the longest mountain bike tour: 74.8 km of marked trail with a vertical drop of 1,245 metres. However, it is possible to shorten it (there are three routes in one). Apart from its length, the special feature of this mountain bike tour is that it takes you into the heart of the mysterious Tournehem-sur-la-Hem state forest.

188 metres of climbing

La Roussie in Lumbres

Discover the many attractions of the Bléquin valley, which takes you to one of the highest points in the département, Mount Drionville at 188 m, as well as to the Côteaux de l’Aa nature reserve and its breathtaking panorama.

Between market gardening and natural marshland

La Cuvette at Clairmarais

A mountain bike trail through the heart of the Audomarois marshlands and the typical village of Clairmarais was a must in this selection. On the outskirts of the Romelaëre ponds nature reserve, the marsh has a different facet: market gardening. These fields bordered by water, known as lègres, are a reminder that the marsh was created by man for market gardening. Then another forest opens up, the Rihoult-Clairmarais forest, one of the largest in the region.
