Boca de San Antonio won't overwhelm you with scale. This is an intimate beach, the kind where you can see both ends without turning your head. The stream arrives from the hills behind the village, carrying runoff that varies from trickle to torrent depending on whether the mountains got rain. In dry months you'll step across it easily; during wet season it can run waist-deep and chocolate-brown, bulldozing new channels through the beach sand overnight.
“The seasonal stream creates a constantly renegotiated beach geography, with the mouth channel shifting position after every significant rain event.”

The mouth zone creates its own ecosystem microclimate. Wading birds—sandpipers, willets—work the margins where fresh and salt water mix, probing for invertebrates that concentrate in the brackish zone. You'll find driftwood jammed against the stream's bank, brought down from interior forests and deposited at tide line. Local families claim traditional spots under scattered palms, stringing hammocks and setting up charcoal grills for weekend fish cookouts. The sand here is coarser than resort beaches, flecked with mica that catches sunlight.
Sunset faces west across the gulf, and from this small beach the view extends unobstructed to the Araya Peninsula. The sky performs in layers—orange near the horizon, pink above that, deepening to violet. The stream mouth reflects these colors in miniature, a small mirror of the larger display. It's sunset scaled to the beach's modest proportions, which somehow makes it more approachable, less overwhelming.
