João Fernandes is Búzios's social beach — the one with the most activity, the most people, and the best infrastructure. The water is calm, clear, and sheltered from the open Atlantic swell, making it reliable for swimming and decent for snorkelling around the rocks at each end.
The beach faces east and catches morning sun first. A row of colourful wooden fishing boats is usually pulled up at the southern end, and the combination of boats, clear water, and forested headlands makes it photogenic as well as pleasant to swim in. Vendors circulate with cold drinks and food.
Chairs and umbrellas are available from the beach barracas (stalls) for a modest daily fee. The barracas also serve cold beer, caipirinhas, and simple snacks. Water sports equipment — kayaks, paddleboards — can be rented here.
