Brazil
Humpback mothers teaching calves to breach at the largest coral reef in the South Atlantic.
You hear the whale before you see it — a low, percussive exhale that carries across flat water. Then the humpback surfaces, her calf tucked close, and the pair drift past the boat in water clear enough to trace the white patterning on the mother's flanks. The Abrolhos reef below is a forest of mushroom-shaped coral towers found nowhere else on Earth, and the light through the water turns them from ochre to gold.
The Abrolhos Archipelago sits seventy kilometres off the coast of Bahia, within a marine national park that protects the largest coral reef system in the South Atlantic. Between July and November, humpback whales migrate here to breed and calve — sightings during this window are virtually guaranteed. The reef formations called chapeirões — stacked mushroom-shaped coral structures — are unique to Abrolhos and found in no other reef system on the planet. Diving visibility regularly exceeds twenty metres, and no anchoring is permitted within the park. The archipelago is reached by overnight boat from the mainland town of Caravelas, and waking up at anchor in a marine sanctuary with no other vessels in sight is part of the experience.
Couple
Whale-watching from the deck of a liveaboard, snorkelling over coral formations that exist nowhere else, and the shared awe of hearing a humpback exhale twenty metres away. The overnight boat journey adds an element of expedition.
Friends
Diving the chapeirĂŁo formations, competing for the best whale photograph, and trading stories over grilled fish and cold beer back in Caravelas harbour. The Abrolhos trip is the kind of shared experience that becomes a reference point for years.
Packed boat lunches of moqueca and rice eaten on deck between whale sightings.
Fresh-caught reef fish grilled in Caravelas harbour after the boat trip back from the archipelago.
