Mexico has 408 beaches.
We counted.
That’s 408named, mapped beaches — real OpenStreetMap geometry, deduplicated, nothing under 1,500 m² of actual sand. The true number is higher (unnamed coves don’t count themselves), so treat this as the verifiable floor. Combined mapped sand: roughly 35.2 km².
The widest of them
