Description of the walk

In Saint-Jacut, park at the Plage des Hass car park on the west coast of the peninsula.

(S/E) From the car park, walk down to the beach and follow the customs officers' path (GR®34) to the right. The path runs along the west coast of the Saint-Jacut peninsula and reaches Pointe du Chevet, located at the northern tip of the peninsula.

(1) From the point, head onto the exposed beach, aiming for the rocky outcrops, first heading southwest, then north.

(2) Pass Petit Ânon and continue north.

::3: Pass La Roche aux Grands and then cross the sandy foreshore to the northeast towards Île des Hébihens.

(4) Just before the island is the islet of La Loge, which you will need to climb over. It can be bypassed to the east if the tide is low enough.

(5) Land on Île des Hébihens at its southern end. A message painted on a rock indicates that the island is private and that visitors are requested not to stray from the path. Take the path northwards.

(6) Pass by the foot of the Hébihens observation tower, built in 1696 based on plans by Vauban. Continue along the path to the northern tip of the island.

(7) Turn around.

(5) Leave the island via the southern entrance and head for Îlot de la Loge.

(4) You may need to go around it on the left due to the ebb tide.

(3) Pass by Rocher des Grands again.

(2) Then via Petit Ânon. From there, leave the route you took on the way there and head south-west towards Petite Roche.

(8) Walk along the left side of Îlot de la Petite Roche. From there, walk along the sandy foreshore towards the south-east in the direction of Plage des Haas. Reach the beach and walk back up to the car park (S/E).

Notes

Be sure to check the tide times before setting off. Depending on thetidal coefficients, the passage may open up to 3 hours before low tide, but in all cases you must return to the mainland no later than 1.5 hours after the indicated low tide time.

On the sandy or sometimes rocky foreshore, the map route is for guidance only. The route can therefore be changed as required and adapted to the conditions.

Whatever happens, never attempt to return when the sandy strip is submerged, as the currents can be very strong.

Worth a visit

The Hébihens observation tower was built in 1696 based on plans by Vauban.

The islet of Petite Roche is ideal for climbing, and its western flank is home to the ruins of an old hut used to monitor the oyster beds.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

This hike was a wonderful discovery. At first, we had to search a little to find the path across the sandbank.
It should be noted that we didn't have boots, but our waterproof hiking shoes did the job nicely.

A pleasant hike with the refreshing feeling of starting the crossing with your feet in the water at low tide.

I did this hike on Thursday 26 June, but without visiting the various rocky islets after the picnic at Pointe du Chevet, which can be reached via the GR34 from Haas beach. I had to wait a while for the tide to go out before I could cross the sandbar towards the Île des Ebihens. I walked there and back on the path authorised for hikers, as the island is private property. You can see the imposing Hébihens tower, built in 1696 based on plans by Vauban.
Be sure to check the tide times indicated on the sign located at the stairs leading down to the beach.

Great hike. However, don't forget to check the tide times and coefficients. It would be a shame to end this superb hike with a tragedy.

It is essential to plan ahead for the tide times. There are many ways to reach the foot of the Hébihens.
We returned via the sandbar that oyster farmers use to reach their farms.

For this route, you need to know the tide times and coefficients (low tide) in order to reach the Hébihens island on foot
and return to the mainland safely.
We were the first ones on the island on the morning of 14 June and took full advantage of the magnificent seascapes. It is a natural site on a private island: it is well worth the detour.
On our way back, we met some walkers, but in June I don't think it gets too crowded.
