Walk ten minutes south from Piedras Coloradas along the coastal track and you'll drop onto Playa La Rinconada, a stretch of beach that doesn't appear on rental agency maps or tour-operator itineraries. The sand here runs warmer in tone than its northern neighbors—ochre and rust mixing with blonde where the cliffs shed sediment. Afternoon light catches the layered rock face behind you, painting stripes of terracotta and cream.

The Patagonian tide here is famously extreme; water retreats hundreds of meters twice daily, leaving behind shallow lagoons that trap warmth. You'll wade into these natural bathtubs while the open gulf stays bracingly cold. Gulls and cormorants work the tide line, and if you arrive in January the beach might host a single family, their windbreak staked against the steady Atlantic breeze.
There's no snack bar, no umbrella rental, no lifeguard tower. Bring what you need in a cooler, claim your patch of sand, and settle into the rhythm of a beach that refuses to perform. By late afternoon the sun slants low enough to turn the shallows into mirrors, and the only sound layering over the surf is the crunch of your own feet on shell fragments older than the resort towns up the coast.
