The Rance estuary on the Dinard side, then Saint-Malo

Walking along the Chemin de Ronde between the dam and the pier, you will enjoy various panoramic views of Saint-Servan-sur-Mer and then Saint-Malo. A short boat trip will take you to an outer basin of the port of Saint-Malo. Continue on to the Cité d'Aleth, the Solidor Tower and the Rosais to complete this tour by crossing the dam.

Description of the walk

Parking in the tidal power plant car park: see note in "Practical information" below.

Apart from a few very short sections, the route follows theGR® 34 and is therefore entirely marked in white and red.

(S/E) Leave the car park via the stairs and then the path that leads to Rue du Grand Mat. Follow this road, turning right. After a 90° left turn at the crossroads, continue right onto Avenue de la Rance. Ignore the dead end on the left and continue for another 50 metres.

(1) Turn right onto a path and continue right onto Chemin du Port Vicomté. Keep left to follow Chemin de Ronde, which runs along the coast.

(2) Turn right onto Avenue Port Bernard and go around Pointe de la Jument via Chemin de Ronde. Stay as close as possible to the coastline and then go around Pointe de la Vicomté.

(3) Off route: at low tide, you can walk along the foreshore, turning right to reach the Priory.
When you reach Rue de Port Nican, turn left to follow theGR® route at high tide.
At the crossroads, turn right and follow Avenue de la Vicomté on the right.

(4) Turn right to reach the coast and walk along Prieuré beach. You will find the Chemin de Ronde, which runs close to the shore and leads to the "Corsaires" ticket office for the crossing of the Rance.

(5) Once on the boat, take a few minutes to rest and admire the scenery.

(6) There are two different places where you can disembark in Saint-Malo:
- at the slipway opposite the ramparts (marked on the map): turn right towards the Esplanade de la Bourse, then turn right at the Chaussée Éric Tabarly roundabout,
- at the ferry terminal: cross the building and, after crossing the car park, join the Chaussée Éric Tabarly and turn right.
Cross the lock of the dry dock basin, then take the sliding bridge that marks the entrance to the port basins. Follow the Terre Plein du Naye to the right, pass in front of the customs gatehouse and turn right to reach the shore.

(7) Follow the promenade around Baie des Bas Sablons and arrive in front of the Maritime Police gate.

(8) Go through the gate. Watch out for vehicles travelling in both directions, even though there is a sign indicating "Priorité Piétons" (pedestrians have right of way). Turn right immediately and go around the memorial museum and the entire Cité d'Aleth peninsula. Join the Allée du Marégraphe and continue to the Allée Gaston Buy.

(9) Opposite are the ruins of the medieval cathedrals of the Cité d'Aleth.
Turn right and then right again to reach Anse Saint-Pierre, then turn left. On your right stands the proud Solidor Tower. Continue left and go down into the garden below to admire the memorial to the sinking of the Pourquoi-Pas and its captain, Commander Charcot, on 16 September 1936.
Continue along Quai Solidor, then turn left towards Parc des Corbières.

(10) Enter the park. At the top of the hill, turn left and go through a small gate.
Be careful, as the route is very challenging for almost a kilometre, with numerous steep steps going up and down.
Walk along the Côte des Corbières and arrive at Rue des Fours à Chaux.

(11) Turn right. Cross Rue de l'Enfer and continue straight ahead onto Impasse de la Rance. At the end, turn left and continue to Boulevard du Rosais.

(12) Turn right. Go around the marine cemetery and descend to the right onto Chemin du Vau Garni. Continue along the path on the right until you reach a stone passageway.

(13) Off the route, turning left gives you the option of making a round trip to the park and Château de la Briantais. See note below "During the hike"
Cross the passageway and continue along the path. Go around the Pointe de la Briantais and you will come to a fork.

(14) Turn right and you will reach the side of the road. Turn right and take the footpath. Cross the dam and you will reach the car park. (S/E)

Reminder: to reach the car park on the pier side, you must use the pedestrian tunnel.

Notes

This walk was completed by the author in April 2023: at that time, a single crossing on the ferry connecting Dinard to Saint-Malo cost €5.90.
With this crossing, the actual distance of the hike is reduced by 2 km, making it 11.86 km in total.

For convenience, this hike starts at the dam of the Rance tidal power plant. The start can be moved to Saint-Malo or Dinard, but it should be noted that although there are many parking spaces in Saint-Malo, they are rarely available, and in Dinard there are few parking spaces, so they are also difficult to find.

Use one of the two car parks on the Dinard side:
- for those coming from Rennes or Saint-Malo, use the car park on the right just after crossing the dam and the lock lights.
- For those coming from the west: Saint-Brieuc or Dinard, use the car park on the right before the traffic lights, but be careful when going to and from the start of the walk, as it is strictly forbidden to cross the road. There is an underground passage for pedestrians to cross to the other side of the road.

A superb circular offering beautiful views of St Malo and St Servan. The sea shuttle allows you to fully enjoy the estuary landscapes.
The route is easy overall, with one more challenging section between St Servan and the dam, east of the estuary

Thank you for this wonderful suggestion!

This hike perfectly combines sea and history, nature and heritage.

In less than 15 kilometres, between stairways, varied viewpoints and stops to admire a detail or a landscape, you progress at your own pace, making discoveries along the way. The boat trip between Dinard and Saint-Malo adds a unique touch, offering a change of scenery and a rare feeling of escape.

You then walk between cliffs, beaches, military ruins and charming streets lined with villas. It's a rich and surprising route that makes you want to finish with a well-deserved crêpe.

A beautiful hike (about 250 metres of elevation gain) starting from the Rance dam with the sea by your side the whole way.
The little extra something about this hike is taking the shuttle from Dinard to get to the ramparts (take the opportunity to have a look inside) – it's really worth it. The walk past the SOLIDOR tower is also very nice.
DON'T MISS IT 😃

Very pleasant hike, but the return trip by boat was not possible during the off-season. I will do it again in May.

Superb hike. It's a great idea to do a circular with the Dinard-Saint Malo shuttle. This allows you to see two coastal paths with very different trees and a magnificent view of the entire bay. Of course, the Rance dam is interesting with its information panels, and with a bit of luck you can see the sailing boats passing the dam with the bridge raised.

Very pleasant parish-specific to Brittany hike. A few urban sections and the end with the dam crossing are not very pleasant, but they do allow you to see the dam in action.

Excellent hike, breathtaking views of the ocean, allow about 4 hours of walking.
Boat crossing between Dinard and Saint Malo.
Good walking shoes recommended.
Steep paths in places.
Signposting on the Saint Malo side is almost non-existent, which is a shame!
I recommend this hike 👍

A very beautiful walk that is easily accessible to any adult in good health. There are a few flights of stairs with high steps that may be difficult for young children.
We set off from St Malo intra muros. The circular route offers varied landscapes. The path, which almost always overlooks the bay, is well maintained throughout. Crossing the Rance dam is quite unusual. The return trip by sea shuttle between Dinar and St Malo adds an extra touch to this hike, which is not particularly difficult.
Surprisingly, we saw very few people there.

On the Dinard side of the Rance dam, the signage is very good.
However, the signage for the St Malo/Rance dam section is confusing in some places. It appears that work has been carried out there recently.

A really nice route, with the emerald sea always in view. The short boat trip is very pleasant, but be aware that the ferry company stops operating during the winter. The GR markings on the last section are not easy to find. Worth doing again.

I am from Toulouse, but as I have family ties in Dinard, I have already had the opportunity to do this hike several times and I can confirm that it is simply SUPERB.
Thank you for posting it on the website for everyone to enjoy.
