L'M - Fermeture temporaire

ATTENTION: 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 around fifty varied routes ranging from 4c to 6c, the vast majority of which face due west. Owned by the Montreuil City Council, this area underwent a major renovation in 2021/22 with new, modern, and sporty equipment, but it remains classified as an adventure climbing site—so climbers should exercise caution! Please note: The cliff is closed between March and June to avoid disturbing the peregrine falcon that nests there each year. Please respect this closure to avoid permanently losing this climbing area. 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.
