Circle the Lagoon: Urban Nature and Motion at Rodrigo de Freitas

It’s 6:30 a.m. and the city is still soft-edged—murmurs of traffic, the last stars folding into a cotton-gray dawn. A narrow band of fog clings to the water of Rodrigo de Freitas Lagoon as joggers and cyclists slice the paved path that loops the shore. The mountains—Morro Dois Irmãos, the crag of Corcovado with its distant silhouette of Christ the Redeemer—stand like sentinels around the bowl of water, their reflections trembling when a rower skims through. Here, in the heart of Rio’s South Zone, the lagoon is both a backyard and a stage: locals exercising, families feeding birds, fishermen casting lines, and guides arriving with e-bikes and scooters to ferry visitors around a nearly flat, photogenic 7.5-kilometer circuit.
