The Gay shelter is a fairly large cavity located in the Jura massif, in the town of Poncin (Ain), at an altitude of 275 m.

The sedimentological and palynological study of the shelter, conducted over 10 m in height, has highlighted human occupations ranging from contemporary times to the final Magdalenian.

The Gay shelter is one of the eight caves in the Jura region and the Rhône basin that have provided Azilian artifacts, in this case, eleven painted and/or engraved pebbles very similar to those discovered in the cave of Mas d'Azil in Ariège.

The Gay shelter is on the list of classified natural sites of Ain.
