Mar de Ajó, Beach town in La Costa Partido, Argentina
Mar de Ajó is a coastal town in Buenos Aires Province featuring wide beaches with fine beige sand and clear shallow waters. The shoreline slopes gently into the Atlantic, making it suitable for swimming, paddling, and other water sports.
The area was originally called Rincón del Tuyú until an expedition in 1580 resulted in its current name. This change came about when white clay deposits were identified along the shore by people who explored the region.
The name comes from Guaraní people who recognized the white clay found along the coast. Fishing remains part of daily life here, with locals and visitors often gathering at the water's edge to watch the catch.
The town is most pleasant to visit from December to February when the water stays warm and daylight lasts longer. Early mornings and late afternoons are the best times to find the beaches less crowded.
In the Nueva Atlantis area, remains of old merchant ships emerge from the water at low tide. These sunken vessels from the 1800s serve as unusual reminders of the region's maritime past.
