The count · Thailand
Thailand has 587 beaches.
We counted.
That’s 587named, 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 22.7 km².
