Anais is located some 15 km east of
La Rochelle and 5 km south by south-east of
Nuaille-d'Aunis. It can be accessed by the D107 road from
Dompierre-sur-Mer in the west passing through the centre of the commune south of the village and continuing to
Bouhet. The D113 road also comes from
Virson in the south passing through the southern part of the commune and continuing north-east to
Le Gué-d'Alleré. Access to the village in the north of the commune is only by small country roads running off the D107 and the D113. Apart from the small village of Anais there is also a larger village called
Les Grandes-Rivieres located on the D113 road. The
Curé stream forms the eastern boundary of the commune and the Virson forms the northern part of the western boundary and they both meet at a place called
le Gouffre (the Pit) which is the start of the Canal du Curé on the municipal boundary of the neighbouring commune of
Angliers. The small village of Anais is built on a low limestone hill, at an altitude of about 13 metres, and it is surrounded by numerous marshes, being located in the southern part of the
Marais Poitevin which belongs geographically and historically the plain of
Aunis. It is in this part of the Marais Poitevin that the course of the Curé enters the vast marshy bowl after leaving the last calcareous soils of
Aunis in the neighbouring commune of
Bouhet.
