Official website
Where to find it
Mont Saint-Michel Abbey's official website is abbaye-mont-saint-michel.fr, run by the Centre des Monuments Nationaux (CMN), the French state agency that administers many of France's heritage sites. It is the source of truth for opening hours, exceptional closures (like Monday 1 June 2026), current and upcoming exhibitions, the Rêve de Lune Nocturnes programme, and any press matters.
What the official site offers
Detailed information about the abbey's architecture and history, presented by CMN curators. Calendars of upcoming exhibitions, special events and the Nocturnes evening programme. Group booking forms for schools, tourism professionals and large parties. Press accreditation requests. Listings for the daily Mass schedule of the Fraternités monastiques de Jérusalem who live in the abbey.
How this site differs
This site exists to make booking faster, with a clearer mobile experience, in your language, and with flexible cancellation up to 24 hours before your slot. Tickets here include the same abbey admission as those bought at the CMN counter on-site or via the official site. For institutional questions, group bookings of more than 20 people, or any matters relating to the CMN administration, please use the official site.
Phone enquiries to the abbey: +33 (0)2 33 89 80 00, daily during opening hours.
