Snorkeling in Brazil
Including Aquário Natural, Baia dos Porcos, and Baía do Sancho. On the map.
The vibe
Floating in these waters feels like peering into a vibrant, high-contrast aquarium where the visibility is often dictated by the shifting tides and river runoff. It is best enjoyed during the dry season when the seas are calm and the silt settles, offering a clear look at the reef life. You will find a mix of organized boat trips that cater to casual swimmers and quiet, independent spots where you simply walk off the shore with your own mask.
