This huge, estuarial beach at the junction of Bahía de Todos Santos and Río San Carlos lies about 12 kilometers south of the center of Ensenada via Mexico 1, behind Ejido Chapultepec.

Not everyone will find the beach—which tends toward mudflats at low tide—to their tastes, but the area is quiet and nice for beach-walking, surf-casting, and bird-watching. Opinions differ as to just how clean the water is, but plenty of folks swim here without any complaints.

The turnoff from Mexico 1 is 7.5 kilometers (4.7 mi) south of the Gigante at Avenidas Reforma and Delante. Except during July and August, the beach is surprisingly uncrowded.

The Estero Beach Museum (daily 9 a.m.–5 p.m., US$5), part of the Estero Beach Resort complex, offers natural-history exhibits and a display of Mexican folk art.
