Saint-Malo, France: Things to Do, Tides and Day Trips (2026)
Saint-Malo is Brittany's most famous seaside town: a granite walled city surrounded by the sea, with ramparts you can walk all the way round, tidal islands you can reach on foot at low tide and wide sandy beaches. It was the home port of the corsairs who raided English ships for the French king, and of the explorer Jacques Cartier. This guide covers the best things to do in Saint-Malo, France, how the tides work, how to get there from Paris and the best day trips, including Mont-Saint-Michel.

10 best things to do in Saint-Malo
1. Walk the ramparts
The best introduction to Saint-Malo is a walk along the ramparts, about 2 km all the way round the walled city. They are free and open all day, with views over the beaches, the islands and the port on one side and the tall granite houses of the old town on the other. Go at sunset, or at high tide on a windy day, when waves crash against the walls.
2. Explore the walled city
Inside the walls, the narrow streets are full of crêperies, shops and old shipowners' mansions. Almost all of it is a careful reconstruction: around 80% of the walled city was destroyed in the fighting of August 1944 and rebuilt stone by stone after the war. Visit the Cathedral of Saint-Vincent, with its striking modern stained glass, and look for the plaque marking where Jacques Cartier is buried.
3. Walk to Fort National at low tide
At low tide, you can walk across the sand from the Plage de l'Éventail to Fort National, built in 1689 to plans by Vauban, Louis XIV's great military engineer. Guided visits run in summer when the tide allows and the flag is flying; check times locally, and always watch the tide on your way back.
4. Visit the Grand Bé and Chateaubriand's tomb
The tidal island of the Grand Bé is reached by a causeway at low tide. At the top is the simple grave of the writer François-René de Chateaubriand, born in Saint-Malo in 1768, who asked to be buried facing the sea. The tide comes in fast here, so check the crossing times shown on the signs at the start of the causeway.
5. Swim at the Plage du Sillon and Bon-Secours
The Plage du Sillon stretches for about 3 km from the walls towards Paramé, with fine sand and a promenade lined with wooden breakwaters. Closer to the old town, the Plage de Bon-Secours has a seawater pool, refilled by every high tide, with a diving board that is a classic Saint-Malo photo.
6. Watch the tides
Saint-Malo has some of the biggest tides in Europe: on the strongest spring tides, the sea can rise and fall by more than 12 metres. At low tide, beaches, rocks and islands appear; at high tide, the water reaches the foot of the walls. The equinox spring tides in March and September are spectacular, especially in a storm. Always check the tide times before walking out to the islands.
7. Eat galettes, crêpes and oysters
Brittany is the home of the buckwheat galette, served with ham, egg and cheese, followed by a sweet crêpe and a bowl of local cider. Saint-Malo is full of crêperies, and nearby Cancale, about 30 minutes away, is famous for its oysters, eaten fresh at the market stalls by the harbour.
8. Visit the Grand Aquarium
On the edge of town, the Grand Aquarium is a good rainy-day option and popular with children, with a shark tunnel and a large circular tank of fish from local waters and further afield.
9. Take the ferry to Dinard
A small passenger boat crosses the mouth of the Rance to Dinard in about 10 minutes. The elegant Belle Époque resort has grand villas, sandy beaches and a lovely coastal path, and it is a perfect half-day trip with views back to the walls of Saint-Malo.
10. Take a day trip to Mont-Saint-Michel
Mont-Saint-Michel is about an hour away by car or tour, making it the most popular day trip from Saint-Malo. Combine it with Cancale and the Pointe du Grouin, or with the medieval town of Dinan on the Rance. Our Mont-Saint-Michel guide explains how to visit and how the tides work there.
Planning a trip to Brittany and Normandy? Hotels inside the walls and on the Sillon fill up early in summer. Compare flights and hotels for your dates.
How to get to Saint-Malo
- Train from Paris: direct TGVs from Paris Montparnasse take about 2 hours 20 minutes to 2 hours 45 minutes. The station is about 15 minutes' walk or a short bus ride from the walled city.
- Ferry from the UK: overnight and day ferries arrive from Portsmouth, and there are fast ferries from the Channel Islands. The ferry terminal is just outside the walls.
- By car: about 4 hours from Paris. Use the car parks outside the walls, as space inside is very limited.
- By air: the nearest major airports are Rennes and Nantes, both connected to Saint-Malo by train.
Our tip: plan your day around the tide table. Walk to Fort National and the Grand Bé at low tide, and come back to the ramparts at high tide to see the sea against the walls.
Where to stay in Saint-Malo
Stay inside the walls (intra-muros) for atmosphere and evenings on foot among the restaurants. For beach holidays and sea views, the Sillon and Paramé seafront has more space and modern hotels, with a pleasant walk along the promenade to the old town. Book early for July and August and for weekends in spring.
Best time to visit Saint-Malo
June and September are the sweet spot: long days, warm enough for the beach and fewer crowds than July and August. Spring and autumn bring the biggest tides and dramatic skies, while summer is busy and lively. Brittany's weather changes quickly, so pack a waterproof whatever the season.
