Playa Las Dunas occupies Monte Hermoso's western flank, where the coastline opens up and the built environment gives way to sand formations that shift with each season's wind. The beach runs wide and flat at low tide, leaving firm ground for long walks and enough space that even on sunny weekends you can claim territory without hearing your neighbor's radio. The dunes behind—some reaching four meters—aren't just scenery; they're living architecture, their contours redrawn by the southwest wind that never quite stops.

Families spread out here precisely because there's room to let children run, to set up shade without encroaching, to body-surf the shore break without dodging a crowd. The water stays shallow for dozens of meters, warming under the summer sun to temperatures that make the Patagonian current feel forgiving. By late afternoon the light turns honey-colored, casting long shadows from the dune crests and painting the wet sand in shades of copper.
You won't find beach clubs or umbrella rentals—Las Dunas trades convenience for openness. Bring what you need, pack out what you bring, and settle into the rhythm of a beach that prioritizes space over service. The western exposure means you can watch the sun sink toward the pampas, the horizon unbroken except for the occasional fishing boat working the offshore current.
