フロセの湖・トップ6

This lake is otherwise called the Mabille valley lake. It is an artificial lake. Access to the leisure center is free. The activities offered here are: picnic on the bank, play areas for the youngest, fishing.

The “Blue Hole” brings together three old granite quarries, at a place called “La Garenne”, on the road to Donges. They were formerly located on the banks of the Loire. They filled naturally with water after their operation ended in 1980. Its name is due to the blue color of the water.

Former limestone quarry now transformed into a protected natural area with a pond in the northern part and a wetland in the southern part. Important birdlife. The paths and trails are well maintained, mainly for mountain biking and gravel.

The Lac de la Vallée Mabille is an ideal place to run. The tracks are impeccable thanks in particular to the GR3 which runs along its banks.

Lac de la Vallée Mabille, more commonly known as Lac de Savenay, is a beautiful body of water located at the eastern entrance to the town of Savenay. Artificial, the lake hosts many activities on its shores: a swimming pool, a campsite, a leisure park, a golf course and a hotel-restaurant. Very famous among the locals, this little green setting is also a delight for long-distance hikers. Indeed, the iconic GR 3 meanders along its banks.

Quiet and cycle park, crossed by the La Blanche river, which forms a pond here. Picnic tables, toilets. Perfect for a short break
