The short version
- The Mont is a village of about twenty residents on a rock in a bay where the tide rises and falls up to 15 meters, with the abbey on top. The village and the ramparts are free; the abbey costs €16 from April to September and €13 from October to March, and it takes about 350 steps to reach it.
- Our Mont St. Michel Day Trip meets your 7:00 a.m. train at Saint-Malo station and gives you three hours on the Mont with the abbey ticket in hand, plus Saint-Malo and Dinan, and the TGV home from Rennes, $195 per person.
- Without us, it is the TGV from Montparnasse to Rennes, about two hours, then the Keolis coach, 1 hour 15, €25 return, three round trips a day in summer and two from November 2, when the last one back leaves the Mont at 16:45.
- Everyone arrives at the car parks 2.5 kilometers out and takes the free shuttle, 12 minutes, which drops you 350 meters from the gate, or walks the bridge in about 40 minutes. Parking is €14 to €28 for the day, by season.
- The abbey opens at 9:00 from May to August and 9:30 the rest of the year, with last entry an hour before closing, and sells timed tickets a month ahead; booking is strongly advised. No suitcases or large bags, and nowhere to leave them.
- At the biggest tides the sea surrounds the rock for about an hour and the end of the bridge floods. The next strong ones are October 27 to 29 and November 26 to 28, 2026. Arrive one to two hours before high water.
What to see
The abbey is the point. A sanctuary was consecrated here on October 16, 709, the Benedictines arrived in 966, and the Merveille, the three-story Gothic block on the north side with the cloister and the refectory, went up in the early 13th century. It was a prison after the Revolution, and monks came back in 1966. A 45-minute guided tour is included in the ticket, and in July and August the abbey opens again at night, 19:30 to midnight, €21 in 2026.
Below it, the Grande Rue is the village’s one street, entered through three gates, the last with a drawbridge. The Mère Poulard inn has made its omelette here since 1873, and the crêperies do galettes and salt-meadow lamb. Walk the ramparts, free, linking seven towers; the North Tower is the place to watch the tide come in.
The tide is the other show. The sea goes out 15 kilometers and comes back fast, strongest 36 to 48 hours after a full or new moon, when it reaches the rock about four and a half hours after it turns. Watch from the ramparts, from the dam, or from the Grouin du Sud across the bay. Never walk out into the bay alone; the quicksand is real.
Guided bay crossings leave from the Bec d’Andaine at Genêts with a certified guide, barefoot, from an hour and a half to a six-hour round trip, in season.
The four private museums on the rock cost €9 each or €18 together, open 10:00 to 17:00. The abbey’s medieval manuscripts are kept on the mainland, at the Scriptorial in Avranches.
Getting there and around
The usual route is the TGV from Paris Montparnasse to Rennes, about two hours, then the Keolis Armor coach from the bus station next to the train station, 1 hour 15, €15 one way or €25 return, booked online or at the bus station, never on board. From March 30 to November 1 it runs three times a day, leaving Rennes at 8:45, 10:45 and 13:00 and the Mont at 11:35, 16:45 and 18:00; from November 2 it drops to the 8:45 and 13:00 out and the 11:35 and 16:45 back.
Since October 12, 2026 SNCF also sells a €32 flat fare from Paris Montparnasse to the Mont, train and coach together, one round trip a day: Monday to Thursday by Villedieu-les-Poêles and a coach to the car parks, Friday to Sunday by Pontorson, the nearest station, 9 kilometers away, and a shuttle to 350 meters from the gate.
Whoever you come with, you end at the car parks 2.5 kilometers from the rock. The free Passeur shuttle runs at least every 12 minutes from 7:30 to 23:00 most of the year, 8:30 to 22:00 from November to February, and the walk across the 2.2-kilometer bridge takes 35 to 45 minutes. Hotels at La Caserne, the strip by the dam, give their guests a code for the barrier.
Our day skips all of that: the guide meets your train at Saint-Malo, drives you to the Mont with the abbey ticket bought, then to Dinan and the Rennes TGV. From Paris door to door, the private tour leaves your address at 7:00 a.m. and has you on the rock before the big buses arrive around 11, $2,425 for up to seven. To pair it with the D-Day beaches, there is a one-day combination from Bayeux or Rennes and an overnight with a night in Bayeux, 90 minutes away.
When to go
The Mont’s own advice is to be on the rock before 10:00 or after 15:00 from March to October. Our day trips run March to October, and the private tour runs all year except Christmas, New Year’s Day and May 1.
Winter is the quiet version: the abbey at €13 and open 9:30 to 18:00, free on the first Sunday of the month from November to March, two coaches a day from Rennes, the Saint-Malo coach Monday to Saturday only, and parking free from 18:30. The abbey closes on January 1, May 1 and December 25.
For the tides, the strong dates left in 2026 are October 27 to 29 and November 26 to 28, with coefficients up to 100; the 2027 tables are not out yet. The abbey’s night openings ran July 3 to August 30 in 2026, and the marathon around the bay is March 20 and 21, 2027.
Expect wind on the bridge in any season and rain in any month. The abbey closes its outdoor areas in bad weather.
Frequently Asked Questions
How do you get from Paris to Mont-Saint-Michel?
TGV from Montparnasse to Rennes, about two hours, then the Keolis coach, 1 hour 15, €25 return, three times a day in summer and twice in winter. Or SNCF’s €32 train-and-coach fare, once a day. Our tour meets the 7:00 a.m. train at Saint-Malo instead, and the private tour drives you from your Paris address.
How much is the abbey, and do you need to book?
€16 from April to September and €13 from October to March, free under 18 and for EU residents under 26. Tickets are timed and go on sale a month ahead; the abbey calls booking strongly advised, and busy dates sell out. Our Mont day trips include the ticket.
When does Mont-Saint-Michel become an island?
At the biggest tides, a few days a month around the full and new moons, when the water covers the end of the bridge for about an hour. The next strong ones are October 27 to 29 and November 26 to 28, 2026. Be on the rock one to two hours before high water, and expect to wait an hour or more to leave.
Can you stay the night on the Mont?
Yes. A few small hotels stand inside the walls, with limited amenities, and you carry your bags up the Grande Rue from the shuttle stop. The hotels at La Caserne, by the dam, see the lit Mont without the climb. We put our overnight guests in Saint-Malo or Bayeux instead.
Is there a tour from Paris?
Yes. Our Mont St. Michel Day Trip meets you at Saint-Malo station and covers Saint-Malo, the Mont with the abbey and Dinan, $195 or $383 with second-class rail, eight guests at most, Monday, Wednesday and Thursday from March to October. The private day from your Paris address is $2,425 for up to seven, any day of the year except Christmas, New Year’s Day and May 1.
