Morning light cuts across Búzios Bay as the dive boat eases away from João Fernandes and the water rearranges itself into an underwater route. Participants meet a certified instructor who stays at their side underwater, coaching breathing, buoyancy, and route choice while large schools of fish thread between granite outcrops. Ilha de Âncora — the Turtle Sanctuary — is the flagship site: rocky pinnacles, sandy flats, and ledges drop to about 22 meters with typical visibility around 15 meters and spikes past 25 on clean days. Water temperatures range from 19–24°C, so divers commonly wear 3–5 mm suits.
