The Blue Flag is fluttering above the beach


The Saint-Cyr Park and its sandy beach, in partnership with the Beaumont Saint-Cyr municipality, have been certified Blue Flag for the first time in 2020.
Renewed in 2021 and 2022, this environmental and touristic international label assures excellent quality bathing water for seaside resorts and lakes.

It is also a guarantee for environmental education, environment as a whole, and water and waste management.

The sandy beach of the Saint-Cyr Lake is the only one in the department to have this label.

Water tests and checks are led by the Regional Health Agency (ARS) on a regular basis, during summer season. This way, you can bathe in total peace!

A study of the lake bed also called bathymetry has been executed in order to determine the depth of the different zones of the lake. The area dedicated to monitored bathing does not exceed a 1.50 m depth.

A daily environmental commitment

As it is fundamental to protect the environment and the biodiversity of the Saint-Cyr Park, our teams are invested, for several years already, in an environmental process they value. Since the opening of the Park, a choice has been made to not allow motorised boats (beside lifeboats) in order to preserve tranquillity and quietness for the visitors but also for the animal and vegetal species that inhabit the site.

Good practices like energy saving (solar panels, water recovery), waste sorting, using nature based products, ordering supplies made from recycled materials (paper sheets, urban property : tables, benches, bins,…) are habits taken by our collaborators. Everything is implemented to respect this commitment and maintain a good quality service.

Fishing on the lake is allowed along the rules of No-kill (the fish must be released).

We also encourage our visitors to sort their wastes at it is important for us to share our values and to include you in this process in order to be able to enjoy for a long time this remarkable surrounding nature.

Outstanding biodiversity


The 300ha of the Saint-Cyr Park shelter an often-unexpected fauna and flora.

Since 1981, the Park has been the object of a regular ornithological monitoring by the Poitou-Charentes antenna of the French bird protection association (LPO).

Since 2009, a 40ha bird reserve, managed and animated by the bird protection association, is established on site and aims to turn into a Regional Nature Reserve in the near future. The bird sanctuary has some rare species: 213 bird species, 32 dragonfly species, 7 amphibian species, 277 vascular plant species and 11 natural habitats have been identified. There, one can gaze at a crested grebe, a common tern, a white-tailed lapwing, or even a mute swan, as well as several dragonfly species, marble newts, bee orchids or guinea-hen flowers.
