Tour of Grande-Île in Chausey

Chausey Island (more specifically La Grande Île) is a must-see for tourists visiting the Channel Islands and the surrounding region. This route takes you on a pleasant and comprehensive walk around the island.
The island itself is exceptionally wild and beautiful. So, too, are the surrounding seascapes. It is said that at high tide there are as many islands visible as there are weeks in the year (52), and at low tide as many as there are days in the year (365).

Update September 2026: unfortunately, this island is entirely covered by private property, including a property management company (SCI) representing the three owners, which refuses to allow access to several parts of the island. The route has therefore been modified accordingly and loses some of its appeal, notably Gros Mont in the north-west, the Pointe de Bretagne in the south-west and the summit at +26m.

Description of the walk

The car was left parked in Granville. The crossing to Chausey is by boat with a specialist operator or by private pleasure craft.

(S/E) From the wooden jetty on stilts, jutting out into the Sund, head for the mainland, leave the Grande Cale on your right and follow the small road up to the first houses. Head east straight away, towards the old fort (construction began in 1859 on the orders of Napoleon III, completed in 1866).

(1) Walk round it to the north-east, make a return trip through the fort’s entrance, then pass the pyramid-shaped tower – known as the Lambert Tower (which serves as a navigational mark for sailors) – on your left, and follow the path to the lighthouse (built in 1847).

In front of the entrance to the lighthouse grounds, take a very good path on the left, which passes between the houses and runs along the seafront to the south. This south-western part of the island belongs to the French State, which has permanently allocated it to the Conservatoire du Littoral.
Walk past the old fort to the west and reach Port-Marie beach. At low tide, the seabed is exposed for a great distance.

It is one of only two beaches where swimming is permitted and the only one that is lifeguarded from 15 June to 15 September.

Continue along the path which skirts the beach to the north.

Make your way to the Pointe de Bretagne, staying strictly on the only authorised path, without cutting across or straying onto the numerous tracks to the left and right, where the thick scrub of broom and other thorny plants prevents you from approaching the southern shore outside these tracks... Pass the ‘Stèle’ monument on your right and continue along the path on the island’s western shore. Keep the imposing Château-Renault building in your sights.

(2) Walk alongside this château on the sea side, leaving its granite-carved swimming pool on your right and passing along the south-west-facing Port Homard beach. Then head north to reach the Grande Grève beach, which faces due west, where fishing vessels used to run aground to have their hulls maintained, depending on the direction of the wind.

This is the second beach authorised for swimming, but it is unsupervised.

Retrace your steps from the beach and head due east back towards the start. This will take you to the village of Les Blainvillais. Here you’ll find numerous fishermen’s cottages (or old houses), the old farm and a holiday centre. The charming cove of Les Blainvillais opens out onto the Sund; it’s a picturesque spot. You can make a detour to the north-eastern cove which flows into the channel and even walk along it at low tide.

(3) Continue round the island heading south-east, making sure not to miss the island’s chapel and its small dolmen, which was uncovered some twenty years ago by Father Delaby, the last resident parish priest on the island.

(4) A little further on, on the right, on a large lawn, walk around the typical, well-restored houses (not yet off-limits). After this lovely walk, return to the starting point of the route (S/E).

You can also choose to return to Port Marie Beach whilst waiting for the ferry, by taking the short path heading south-south-west.

Notes

Warning
- The route is suitable for adults and accompanied children, but not for people with reduced mobility.
- You will be held liable in the areas indicated (see map here) if you fail to comply with this restriction.

Estimated time
I completed this route on foot in 3 hours, including breaks and photo stops. This is a fairly generous estimate. However, to really enjoy the area, especially in fine weather, allow 3 to 5 hours for a family outing.

Drinking water
There are no drinking water points along the walk. Please bring what you need. However, a drinking water tank is available to everyone at the Grande Cale…

Toilets – First-aid post: Near the Grande Cale.

Shelters
There are no shelters along the route.

Equipment
In summer, bring the usual equipment for lowland hiking (hiking boots, walking shoes or trainers, suitable clothing, rainwear, water, food, etc.).
In all seasons, bring a map, a GPS or the Visorando app on your smartphone.

Footfall
High in the village centre and at Les Blanvillais as soon as the weather is fine. Moderate to low on the trails.

The section leading to the signal post is inaccessible; it is no longer possible to reach that part of Chausey Island. The route has been altered.

Hello,

I downloaded the walking route, but didn’t use it.
In fact, there was a sign pointing to the path on the island, and the map was too large-scale to be of any use.

You can still reach the Grande Grève beach and walk there. On Chausey, as the island is managed by a property investment company owned by the island's residents, many areas are private and therefore off-limits to the public. Please refer to this website https://www.tourisme-granville-terre-mer... The map of the island states that you must only walk on the marked coastal path and public footpaths.

That is all the information I can give you.

Can we still win the Great Western Strike and the building at the northern tip, or is it blocked off?
(Or give me the latitude/longitude coordinates of the chain's position if you have them.)

The path to the semaphore is blocked by a chain with signs indicating that entry is prohibited. At the start of the path, there is a sign describing this part of the island, explaining that it is the most fragile part of the island because it is subject to erosion, both natural and caused by travellers trampling on it, hence the prohibition to preserve the area. That's all the information we have.
Best regards

Dear User 27814581,

Thank you for your feedback.
Are there any prohibition signs near the old semaphore or a fence preventing access to the trails marked on IGN?
If not, many hikes pass through private land without any problems.
Kind regards

The route is as described, except for the section of the semaphore, which is closed to the public as the path is private.
