I really enjoyed these four real, straightforward laces in the middle of town. In my opinion, in the centre of Boulogne, this is the most exciting climb. Its route, its gradients and the views it offers once up there make this climb an essential stage for cyclists riding in the Pas-de-Calais. It's very short and rather intense. In the category of urban climbs, it's a strong contender. In short, I loved it!... read more

J’ai vraiment aimé ces quatre vrais et francs lacets en pleine ville. Selon moi, dans le centre de Boulogne, c’est la côte plus excitante. Son tracé, ses pourcentages et les vues qu’elle offre, une fois là-haut, font de cette montée une étape indispensable du cycliste qui roule dans le Pas-de-Calais.
C’est très court et plutôt intense.
Dans la catégorie ascensions urbaines, c’est une belle candidate.
Bref, j’ai aimé !

Behind the main boulevard of Boulogne-sur-Mer (Boulevard Sainte-Beuve) 4 hairpin bends are hidden. From the Aquarium you can drive in 4 steep hairpins to the higher parts of Boulogne. A must for the hairpin fan to try. On the other hand, those who prefer not to cycle in an urban area, better skip it.

Achter de grote Boulevard van Boulogne-sur-Mer (Boulevard Sainte-Beuve) liggen 4 haarspelden verborgen. Vanaf het Aquarium rijdt je in 4 steile haarspelbochten naar de hogere delen van Boulogne. Een must voor de liefhebber van haarspeldbochten om eens een keertje te proberen. Daarentegen, degene die liever niet binnen stedelijk gebied fiest, kan deze beter overslaan.
