Arzal Dam

Highlight • Monument

The Arzal dam is built on the Vilaine estuary between Arzal and Camoël. It is the largest estuary dam in Europe. It is 500 meters long and has a sea wall and five gates. To allow circulation between the river and the ocean, the dam has a lock. A port is also located nearby.

Loguy Picnic Area in Pénestin

Highlight • Rest Area

Behind a hedge under a tree is this bench with a table, perfect for a picnic. Pleasantly shady and quiet. A little further down the beach there is also a table that gets more sun and was occupied. So we enjoyed our lunch break here right next to the V45 route.

The Gold Mine

Highlight • Beach

La Mine d'Or is one of the most beautiful Breton beaches with its cliffs in shades of ocher. You can swim there and practice water sports. It is accessible on foot, although you can take the stairs while pushing your bike.

Port Tréhiguier

Highlight • Structure

Small charming harbor overlooking the Vilaine estuary. Some very nice restaurants and bars for a mid-term coffee or to fill your cans!

The annex at the Port of Tréhiguier

Highlight • Other

It's a very nice place by the sea, with a wide choice of wines, beers and cocktails from all over the world. The café opens every day at 7:30 am (except Monday, closing day), so you can also have breakfast there. There are even concerts and events organized, mainly in the summer.
