Plages des Cavaliers is a sandy sea beach in Pyrénées-Atlantiques, Nouvelle-Aquitaine, in southwestern France. It is listed for naturist use, and nudism is indicated in the supplied map data. Visitors should look for posted signs on arrival and remain within the area associated with naturism. Access appears free and open, generally possible during daylight, with no booking indicated. Reach the sand on foot from coastal paths near parking areas. Parking is available in the surrounding beach area but can fill during summer, so an earlier arrival helps. Local buses serve the coastal area; check current timetables and stops before travel. June through September is a reasonable estimate for warmer beach weather, with busier conditions in summer and quieter periods outside peak months. Morning and late afternoon generally offer milder sun exposure. The beach has an open setting with limited natural shade, so bring sun protection. Lifeguard coverage is indicated in supplied map data, but operating periods and daily presence should be confirmed locally. Coastal water conditions can change with weather and sea state, so check local safety information before entering the water and use lifeguarded areas where available. Food, drink, toilet and shower availability at the beach is not confirmed, so bring water and supplies and plan accordingly. Step-free access is not confirmed, and soft sand may limit movement for wheelchairs and strollers. Dog rules are not confirmed; check posted regulations. Many visits last a few hours for swimming and sunbathing, depending on weather. Conditions can vary through the day, so allow flexible timing for swimming, resting, and time on the open sand.
