Platja de Son Serra de Marina, White sand beach in Son Serra de Marina, Mallorca, Spain

Son Serra de Marina is a beach on the northeast coast of Mallorca with pale sand and a bay framed by pine and juniper forests. The shoreline runs along dunes and stretches between two headlands, with water that shifts in color based on depth and seabed composition.

The area was inhabited in prehistoric times, as shown by archaeological finds of tombs and settlements from Bronze Age and early human periods. These remains suggest the coast was an important living space long before modern settlement.

The beach forms part of Son Real Nature Reserve, where local residents maintain traditional activities amid sand dunes and Mediterranean vegetation.

Access the beach from Carrer Juan Frontera Riera 1–35 in Son Serra de Marina; a free car park on Carrer na Borges at the eastern edge of the village gives level access. The water stays shallow near the shore, so skippers should avoid the area because of the risk of running aground. Seagrass sometimes accumulates on the sand and makes entering the water harder.

The Torrent de na Borges marks the beach's eastern edge; in the dry season it carries no water, so walkers can cross its bed on foot to reach the neighbouring S'Arenal de Sa Canova. The stream mouth shifts the sand and pebbles, so the crossing point changes from year to year.
