Platja de Son Moro, White sand beach in Sant Llorenç des Cardassar, Spain.

Platja de Son Moro is a roughly 600-metre stretch of the Platja de Sant Llorenç, the 1,800-metre beach of Cala Millor, in Sant Llorenç des Cardassar. It runs from the Parc de la Mar to Carrer de Borneo, where the Cala Nau beach begins. Its fine sand matches the southern Cala Millor section, but it is narrower toward Cala Nau and has some flat rock slabs at the water's edge.

Son Moro was a separate coastal spot on the Badia de Son Servera until the late 20th century, when Cala Millor's tourist development expanded south and absorbed it. The Parc de la Mar was laid out in the 1980s. Today only the roads Es Carreró de Son Moro and Camí de Son Moro, plus a shop bearing the name, recall the former place.

The name Son Moro survives mainly in the street names Es Carreró de Son Moro and Camí de Son Moro, and in a shop that still carries it, after the resort of Cala Millor absorbed the old locality. The beach is part of the Platja de Sant Llorenç, named after the municipality of Sant Llorenç des Cardassar, though most visitors now simply call it the beach of Cala Millor.

Son Moro is reached from the MA-4023 coastal road by two routes: Es Carreró de Son Moro, which ends behind a roundabout as Avinguda Badia de Llevant at the Parc de la Mar, or via Avinguda de les Palmeres and Carrer Baladres through Sa Coma to the beach's southern end at Cala Nau. The stretch narrows towards Cala Nau and has flat rock slabs at the water's edge.

The name Son Moro survives mainly in two street names, Es Carreró de Son Moro and Camí de Son Moro, and in a shop that still uses it. The Parc de la Mar, a large circular square with the Sant Llorenç des Cardassar tourist information pavilion, was laid out here in the 1980s.
