Things to Do in Saint-Malo

Saint-Malo packs more history and scenery into its walled peninsula than cities three times its size.

Things to Do in Saint-Malo: Historic Sights and Landmarks

Walk the Ramparts

The 1.7-kilometre circuit of granite ramparts defines the Saint-Malo experience. Built between the 12th and 18th centuries, the walls encircle the entire Intra-Muros old town with panoramic views of the Channel, the bay, and the islands of Grand Be and Petit Be. Access is free and the circuit is open year-round (closed only during extreme storms). Start at Porte Saint-Vincent, the main gate, and walk clockwise. Budget 45 to 60 minutes at a leisurely pace. The best photo spots: the Bastion de la Hollande for sunset views toward Dinard, and the stretch above Plage de Bon Secours for the iconic swimming-pool-into-the-sea shot. For more details, see our best time to visit Saint-Malo guide.

Fort National

Built by Vauban in 1689 on a rocky islet just off the ramparts, Fort National is accessible only at low tide. You walk across the exposed seabed from the Plage de l’Eventail. The French flag flying from the fort signals it’s open to visitors. Entry costs €6 for adults, €3 for children aged 6 to 12, and guided visits (in French, with English summary sheets available) take about 35 minutes. Opening times change daily with the tides. Check fortnational.com before heading out. The fort served as a prison during the French Revolution and later as a German coastal defence position in WWII. For more details, see our events and festivals in Saint-Malo guide.

Saint-Vincent Cathedral

The Cathedrale Saint-Vincent, in the heart of Intra-Muros, mixes Romanesque, Gothic, and Renaissance architecture across 800 years of construction. The stunning modern rose window above the organ was installed in 1971. Entry is free and the cathedral is open daily from 9:00 to 18:00 (shorter hours in winter). Do not miss the tomb of Jacques Cartier, the explorer who claimed Canada for France in 1534, in the north transept. The cathedral was badly damaged in WWII bombing (1944) and its restoration is a story in itself, documented in panels near the entrance. For more details, see our best neighborhoods in Saint-Malo guide.

Chateau de Saint-Malo and Musee d’Histoire

The castle at the eastern edge of Intra-Muros houses the town history museum and the city hall. The Musee d’Histoire de la Ville covers Saint-Malo’s corsair (privateer) golden age, the Newfoundland cod fishery, and WWII destruction and rebuilding. Entry costs €6 for adults, €4 for reduced tickets. Open daily except Mondays, 10:00 to 12:30 and 14:00 to 18:00 (closed Monday and Tuesday in winter). The square tower offers excellent rampart-level views without the crowds on the wall circuit. For more details, see our where to stay in Saint-Malo guide.

Things to Do in Saint-Malo: Tidal Islands and Coastal Walks

Grand Be and Chateaubriand’s Tomb

The larger of the two tidal islands, Grand Be is accessible by foot at low tide via a causeway from the Plage de Bon Secours. The tomb of Francois-Rene de Chateaubriand, the 19th-century writer who was born in Saint-Malo, sits on the seaward edge, a simple granite cross overlooking the Channel per his request to be buried facing the sea. The island is free to access but gated when the tide covers the causeway; check return times carefully or you will be stuck for 6 hours. Allow 30 minutes for the walk and visit. For more details, see our Saint-Malo travel tips guide.

Petit Be Fort

This 17th-century fort on a smaller tidal islet sits between Grand Be and the mainland. Access is free and unrestricted at low tide. The fort itself is occasionally open for guided tours (€5, check the tourist office for seasonal schedules), but even when closed, the scrambling walk across the rocky seabed and the views back toward the ramparts make it worth the trip. Budget 15 minutes each way from the Plage de Bon Secours. For more details, see our Saint-Malo guide.

Plage du Sillon

Saint-Malo’s main beach stretches 3 kilometres from Intra-Muros northward toward Parame. At low tide, the sand extends hundreds of metres seaward; at high spring tide, waves can reach the seawall. Wooden breakwaters (brise-lames) installed in the 19th century create sheltered pockets for swimming at mid-tide. The beach is supervised by lifeguards in July and August at several stations along the Sillon. The seafront promenade is lined with Belle Epoque villas, and several cafes and ice-cream shops stay open year-round.

Things to Do in Saint-Malo: Family and Indoor Activities

Grand Aquarium

The Grand Aquarium de Saint-Malo sits just outside the city centre (Avenue du General Patton, 10 minutes by bus line 1 or 8). It houses over 600 species across 10 themed zones. The highlight is the Nautibus, a submarine simulator that descends through a 360-degree tank with sharks and rays circling overhead. Entry costs €17 for adults, €12 for children aged 4 to 12, and €14 for teens 13 to 17. Open daily from 10:00 to 18:00 (until 19:00 in July and August). Budget 2 to 3 hours for the full visit. The on-site cafe serves decent galettes and crepes.

Demeure de Corsaire (Hotel Magon)

This restored 18th-century privateer’s mansion on the Rue d’Asfeld offers a glimpse into how Saint-Malo’s corsair shipowners lived. Francois-Auguste Magon, who built the house in 1725, ran a fleet of ships that raided English merchant vessels under royal licence. The guided tour (€7 for adults, €5 reduced) takes about 50 minutes and covers the merchant’s office, family quarters, and the rooftop lookout where shipowners watched for returning vessels. Open April through October, Tuesday to Sunday.

Things to Do in Saint-Malo: Day Trips

Dinard

The Belle Epoque resort town of Dinard sits directly across the bay, a 10-minute ferry ride (Compagnie Corsaire, €8.50 return, runs April to November) or 20-minute drive over the Rance barrage. Dinard is Saint-Malo’s posh neighbour: manicured gardens, a casino, and a seafront promenade lined with striped beach tents. The Marche de Dinard (Tuesday, Thursday, and Saturday mornings) is one of Brittany’s best food markets. Walk the Clair de Lune promenade at sunset for the definitive view of Saint-Malo across the water.

Cancale

This fishing port 15km east of Saint-Malo is famous for its flat oysters (huitres plates de Cancale), harvested from beds in the bay since Roman times. Buy a dozen from a waterfront stall for €6 to 8 and eat them on the seawall with a squeeze of lemon. Bus line 10 from Saint-Malo station takes 35 minutes. The Sentier des Douaniers coastal path connects Cancale to the Pointe du Grouin in a 90-minute walk with Channel views all the way.

Mont Saint-Michel

The UNESCO-listed abbey-island is 55km from Saint-Malo, about 50 minutes by car or 70 minutes by Keolis bus (line 17, seasonal). The abbey entry costs €11 for adults, free for EU residents under 26. Go early (before 9:30) or late (after 16:00) to avoid the worst crowds. Check tide times: the mount becomes an island at high spring tide, one of France’s most photographed natural spectacles.
