The beach takes its name from the dolphins—toninas—that occasionally surface beyond the breakers, dark fins cutting through the South Atlantic chop. You won't find palapas or jet-ski rentals here. What you will find: wide-open stretches of coarse sand studded with kelp, the constant Patagonian wind that keeps even midsummer from feeling oppressive, and families who've been claiming the same patch of shoreline for decades.
“The only beach along this stretch where Rawson locals outnumber tourists, preserving an unhurried Patagonian rhythm lost elsewhere on the coast.”

The water runs cold year-round, fed by the Falklands Current, but that doesn't stop kids in neoprene booties from wading in while their parents set up windbreaks fashioned from beach towels and driftwood planks. The sand itself is firm enough to drive on in places, packed hard by tides that sweep in fast and retreat just as quickly. Bring your own everything—shade, snacks, drinking water—because the nearest kiosk is a fifteen-minute walk back toward town.
Come in late afternoon when the angle of the sun turns the wet sand into hammered bronze and the wind finally eases. The families begin packing up their coolers, shaking sand from wool blankets, and you'll have the beach nearly to yourself. It's the kind of place that rewards those who don't mind a little effort for a lot of solitude, where the main attraction is simply having room to breathe.
