The lagoon reveals itself gradually as you cross the dunes from the parking area, first as a shimmer between beach grass, then as an expanse of milk-green water stippled with bird tracks. Egrets stalk the mudflats at low tide, their white plumage stark against volcanic sand that darkens to charcoal where wavelets lap the shore. You can wade waist-deep fifty meters out without encountering current, the bottom firm and ribbed beneath your toes.

Morning is when photographers arrive, their tripods sinking slightly into the wet sand as they wait for the light that turns the water to mercury. Coots and ibises feed in the shallows, unbothered by human presence. The air smells of salt marsh and eucalyptus from the grove that borders the eastern shore, where families spread blankets in the shade and children float on inflatable rings, spinning lazy circles in water that barely reaches their chests.
By afternoon, thermal winds create small standing waves where the lagoon narrows near its ocean outlet. Kayakers launch from the beach, paddling toward the reed beds where black-necked swans nest in spring. The sandbar that separates lagoon from sea shifts with winter storms—some years it breaches completely, turning the lagoon brackish and drawing in mullet that attract cormorants by the dozens. Locals check its configuration like they check the weather.
