ENS - L'Étang du Brachet

-

Passonfontaine's network of peat bogs is exceptional!
These vast wetlands are remarkable reservoirs of biodiversity (butterflies, birds, rare plants, etc.), and also play an important role in regulating and filtering water, and in combating global warming. They are a veritable scientific archive on the history of mankind and climates, thanks to the sediments and pollen trapped in the peat strata.
Orange, yellow, green, pink, white, blue... The Barchet wetland and pond offer a multitude of colours every season!
A 5km loop takes around 2 hours to discover a superb and varied natural environment, with 14 stations detailed in a booklet available to download.

Please note: this trail is currently being renovated and will be operational in 2025.
