Angoulins is located in the northwest of the department of Charente-Maritime some 8 km south-east of La Rochelle and 5 km north of Châtelaillon-Plage in the former province of Aunis. It is a coastal commune on the Atlantic Ocean. Access is by the E602 highway from La Rochelle continuing south-east with an exit in the commune just east of Angoulins town. There is also the D202 from Salles-sur-Mer in the east turning south and continuing to Chatelaillon-Plage. Access to the town is by the D111E1 from the D202 on the southern border continuing through the town and turning east to the motorway exit. Angoulins town has a large urban area occupying almost 50% of the commune, with farmland to the north, east, and west.
Geology
The entire commune is located on Jurassic terrain which completely covers the plain of Aunis. Jurassic Marl and limestone outcrops appear on the surface of the commune and the relief is slightly rolling. The coastal strip of Angoulins, which corresponds to the last extremity of the plain of Aunis, is relatively varied. It alternates between low sandy and marshy shores and high limestone cliffs. Low-lying coasts, which were formerly salt marshes, have today been transformed into oyster beds and are derived from Quaternarysedimentary deposits of marine origin - from the last Flandrian transgression. The sandy coast is situated in a small cove formed naturally by the phenomena of marine erosion and ocean currents. The coastal cliffs are located all around the Chay Point and form a limestone peninsula - a sharp promontory jutting into the ocean. Layers of alternating beds of ooliticmarl and limestone can be seen on the cliffs that line the coast from La Rochelle to Angoulins-sur-Mer. They are highlighted by thick layers of white rocks alternating with layers of very friable sand and mud, formed during glacial periods, also with layers containing various corals from tropical periods. Chay Point, about five kilometres south of La Rochelle, contains many fossils of marine animals and is an especially famous place of palaeontological studies. The limestone thus formed is widely used as a building material in traditional houses in the region.
The population of the town is relatively old. The rate of people above the age of 60 years is higher than the national rate and the departmental rate. As at the national and departmental levels, the female population of the commune is higher than the male population. The percentage is of the same order of magnitude as the national rate.

Sites and monuments
The Church of Saint-Peter is registered as an historical monument. There remains the Machicolations on the walkway that connects the three Bartizans located in the north-east corner and the two corners of the apse. The west façade forms a bell tower wall in a fortified triangle. The Chevet preserves the structure of the walkway between the two Bartizans. The nave is Gothic with arched ribs. The church contains two items that are registered as historical objects:
: An association under the 1901 Act founded in 1976. Originally comprising a handful of enthusiasts and a wooden hut, the association now has more than a hundred members and hosted nearly 2,000 people over the year. An artificial body of water was added to the site in 1990. On the night of 27 to 28 February 2010, the Centre Nautique d'Angoulins was badly affected by the storm Xynthia. The buildings were flooded to an average height of 1.60 m. The club's pontoon for teaching fishing, available to rent, was completely destroyed by the storm; it is currently under reconstruction.
