La Bisexto offers numerous routes ranging from 4b to 8a. The face is mostly south-facing, ideal for soaking up the sun in the mid-season, but it can get very hot there in the summer. Our ethical guidebook is brought to you by the FFME Eure Regional Committee in collaboration with Pascal Bocianowski, the lead route setter for the cliffs along the Seine.
