Lunch: Lagoa Redonda
From the mirante the road curves back south, arriving at Lagoa Redonda around midday — good timing for lunch. The lagoon itself is a roadside revelation on the approach from the north: the water curves in a near-perfect arc against a white dune face, catching the full height of the sky. From the far side of the lagoon, a short hike over the dunes brings you to the beach — worth the detour if legs need stretching after the morning's driving. A meal here, with the dune and the lagoon as a backdrop, is one of the better-placed pauses of the day.
