Es grau, Golden sand beach in Menorca, Spain.

Es Grau is a golden sand beach at the mouth of the S'Albufera des Grau wetland, about 590 metres long, in the municipality of Maó. The village of Es Grau stands directly behind the sand, and the Illa d'en Colom lies across the water, sheltering the bay. The beach closes the northern end of the natural park's lagoon system.

Es Grau lies within the S'Albufera des Grau Natural Park, declared a natural park in 1995 and later named a Biosphere Reserve. The wetland behind the beach, with its reed beds and brackish lagoons, had long been recognized for its birdlife before the protection status consolidated the area. The beach and its dunes form part of the same protected coastal system.

Es Grau village, beside the beach, keeps a small fishing tradition: boats are still pulled up on the sand and the barques de bou, traditional Menorcan lateen-rigged boats, are part of local regattas. The beach lies within the S'Albufera des Grau Natural Park, and the village celebrates its festes in honour of Sant Antoni and Sant Joan.

Es Grau sits at the end of the village of the same name, about 6 km north of Maó, reached by the ME-5 road; the beach is backed by the S'Albufera des Grau wetland, so the sand gives way to dunes and marsh behind. The water stays shallow well out from the shore, and the beach is served by lifeguards in season, wooden walkways and showers. Buses from Maó stop in the village, a short walk from the sand.

The Illa d'en Colom, the islet sheltering the bay, lies within the S'Albufera des Grau Natural Park and is a protected nesting site for seabirds such as Audouin's gull. Landing is not permitted, so the beach is best admired from the sand or the village waterfront.
