L'M - Fermeture temporaire

PLEASE NOTE: THE CLIFF IS CLOSED FROM MARCH 8 THROUGH THE END OF JUNE 2026 FOR BIRD NESTING The M Cliff, named for its distinctive shape, offers about fifty varied routes ranging from 4c to 6c, the vast majority of which face due west. Owned by the Montreuil City Hall, this area underwent a major renovation in 2021/22 with new, modern, and athletic equipment, but it remains classified as an adventure climbing area—caution is advised for climbers! Please note: The cliff is closed between March and June to avoid disturbing the peregrine falcon that nests there each year. Please respect this ban, or we risk losing this climbing area permanently. Our ethical guidebook is brought to you by the FFME Eure Regional Committee in collaboration with Pascal Bocianowski, lead route setter for the cliffs along the Seine.
