Vallée de l'Antenne, Special Area of Conservation in New Aquitaine, France.

The Vallée de l'Antenne is a protected conservation site in western France spanning approximately 1,200 hectares of diverse habitats. The area includes a river system with multiple bends, deciduous and mixed forests, and calcareous grasslands across low-lying terrain.

The Antenne Valley was proposed as a Natura 2000 site in March 1999 under number FR5400473, covering 1,173 hectares, and was validated on 12 February 2004 at 1,208 hectares. The management plan (DOCOB) was approved on the same date, and the Natura 2000 charter followed on 25 February 2009. The Saint-Jean-d'Angély sub-prefecture oversees the procedure, with the Rochefort-based Ligue pour la protection des oiseaux (LPO) as operator.

The valley's name comes from the Antenne, the 48.3 km river that runs through it from its source at Fontaine-Chalendray to its confluence with the Charente. The river's gentle fall, from 50 m to 10 m, creates meanders, secondary arms and marshes. The Ligue pour la protection des oiseaux (LPO) of Rochefort manages the site, and its steering committee brings together mayors, riverside residents, foresters, fishermen and conservationists.

Spring and autumn offer the best conditions for visiting, with mild weather and active wildlife throughout the valley. Wear sturdy footwear as paths wind through wet areas and woodland sections.

The valley harbors rare species such as the European mink and several bat species that shelter in underground caverns. These subterranean networks form a critical part of the habitat for the area's ecology.
