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.

Superb viewpoint from its summit, on a clear day you can see the Saint Nazaire bridge and the surrounding marshes. However, be careful when climbing wooden steps in wet weather with cleats and road shoes.

Tower rocks a bit. Good for getting an overview of the area. If you're already there, go up, otherwise you don't have to travel extra.

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.
