Very nice climb, but do not start without preparation.
The percentages are not really right. Pieces of more than 10% especially in the last km you will be surprised.

Zeer leuke beklimming, maar zeker niet aan beginnen zonder voorbereiding.
de percentages kloppen niet echt. Stukken van meer dan 10% bij zeker de laatste km wordt je verrast.

Easy climb for the most part but the last few km are quite complicated! It's not bad to ride downhill because you have a good visibility, so you can anticipate and hit your best points!

Montée facile dans l'ensemble mais les derniers km sont bien compliqués ! Elle est pas mal à faire en descente car on a une bonne visibilité, on peut donc bien anticiper et taper ses meilleures pointes !
