At the mouth of the Guadiaro River, Playa Lacasitos sits where river meets sea — a beautiful, tranquil stretch of soft sand and calm shallow water that’s perfect for families, beach lovers and nature seekers alike. This beach forms part of the Estuario del Río Guadiaro Natural Area, one of the only wetland habitats on this stretch of Mediterranean coastline and a haven for wildlife.
The Guadiaro estuary is an important wetland reserve (protected natural area), attracting 100+ bird species thanks to its mix of river, reedbeds and sandy shores — including migrants and winter visitors alike.
Though small compared to other nature spots, this estuary is the only wetland of its kind for over 100 km along the coast — making it a special ecological treasure right next to Sotogrande.
Relaxed and peaceful with a laid‑back beach feel — no crowds, no big beach clubs, just nature, calm water and a chance to connect with the wild side of Sotogrande.
