Playa Santo Tomás, Southern coastal beach in es Migjorn Gran, Spain.

Playa Santo Tomás is a 500-metre-long, 40-metre-wide beach on the south coast of Menorca, in the municipality of es Migjorn Gran. Its sea entrance forms a U shape, with a sandy slope and exposure to south, south-east and south-west winds. The water is clear and calm.

The beach transformed from a natural coastal area into a developed resort destination during Menorca's tourism expansion in the 1970s. This period brought infrastructure and residential developments to the surrounding region.

The beach gives its name to the Santo Tomás urbanization that surrounds it, and in Catalan it is called Platja de Sant Tomàs. It draws many local bathers as well as tourists, and in summer it can be reached by bus as well as by road.

Access by road is straightforward, following the signs; parking is free, and in summer the beach can also be reached by bus. The sea entrance forms a U shape, with a sandy slope and exposure to south, southeast and southwest winds. The beach is 500 metres long and 40 metres wide.

An underwater cave system lies near the adjacent Binicodrell section, attracting snorkelers and divers to explore below the surface. This geological feature extends the appeal of the shoreline beyond the sandy beach alone.
