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.

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.
