Marais d'Avalon sensitive natural area

Nestled in the hollow of the Belledonne hillsides, in the north-east of the Grésivaudan valley, the Avalon marsh is located in the municipality of Saint-Maximin, at an altitude of 380 m.

In the municipality of Saint Maximin, this marsh was created in 1262 by Louis XI to serve as a defensive system and a fishpond.

It covers an area of 1.4 hectares and is fed by groundwater and runoff.

Scientific monitoring revealed the presence of 5 amphibian species in 2017, but the European tree frog, which had been observed until 2000, has still not been seen again.
It has been listed as a municipal Sensitive Natural Area (ENS) since 2009, and a partnership has been set up with the Conservatoire des Espaces Naturels de l'Isère.
The marsh is covered with a large reed bed, tall sedges and grey willows.
Many migratory species stop over and feed here.
You can see the grey heron, the reed warbler and many ducks.
The presence of the alpine newt has been recorded.

All year round.

Subject to favourable weather conditions.
