Deze col is eigenlijk het verlengde van Col de Croix-Fry.
Op de top van voornoemde fiets je nog een goede 1,5km door naar de top van de Merdassier.
Dit verlengde stuk is niet zo zwaar er zit zelf een afdaling in. Kortom, makkelijk af te vinken en op de top eindig je ook, dus niet al te druk bovenaan.
