Plage de Gros Jonc is a named coastal option in France, not an automatic “best beach” answer. Choose it only after comparing live water temperature, wind, wave exposure, currents, UV and official notices. Current panels can be refreshed without rewriting the stable source record, which keeps each claim in the correct time frame. Identity and access context come first in the evidence record. The stable place data describes a sand shoreline surface. The data identifies a supervised location; check when that service is actually operating. Toilets are listed in the mapped amenities. Authority-supplied context describes the location as “La plage de Gros Jonc est une grande plage de sable fin…” The recorded map position is 46.16749, -1.37323, which helps distinguish this beach from similarly named places. The nearby list contains Plage du Petit Sergent at about 0.9 km, Plage des Grenettes at about 1 km and Plage des Gollandières at about 2.7 km, giving this page a real comparison set rather than a single-place recommendation. A practical answer needs one last update at the time of travel. Search demand points to swell timing, wind direction and nearshore wave behaviour; the last part of the route and any official parking condition; whether stable amenity records match what is operating; answer them with current data and posted information on the day. A late change in wind, water quality or access is enough to reopen the choice and compare the nearby alternatives. Save the page update time with your plan: marine weather, runoff after rain, seasonal restrictions and temporary closures can make yesterday’s recommendation obsolete.
