Access is by the E602 (D137) highway from La Rochelle continuing south-east with an exit in the commune just east of Angoulins town.

The sandy coast is situated in a small cove formed naturally by the phenomena of marine erosion and ocean currents (Angoulins beach, south of the Chay point).

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 oolitic marl and limestone can be seen on the cliffs that line the coast from La Rochelle to Angoulins-sur-Mer.

Chay Point, about five kilometres south of La Rochelle, contains many fossils of marine animals and is an especially famous place of palaeontological studies.
