From the crystal-clear waters of the Caribbean coast to the rivers flowing through the Amazon rainforest, Brazil boasts a remarkable diversity of underwater ecosystems. While underwater visibility is not always ideal and coral is scarce in coastal waters, the country still offers fantastic experiences for snorkeling enthusiasts. Depending on your chosen location, you may encounter sea turtles, butterflyfish, angelfish, seahorses, as well as freshwater fish and small caimans!
The northeastern coast of Brazil is home to some of the most beautiful coral reefs in the country.
Maragogi, some 80 miles (130 kilometers) south of Recife, is a standout destination, renowned for its crystal-clear waters and vibrant marine biodiversity. The natural pools, known as “galés,” are perfect for snorkeling, offering glimpses of colorful fish.
Another good snorkeling location in this region is Porto de Galinhas. Here, you can snorkel in natural tidal pools, where you’ll encounter a variety of fish species including surgeons, puffers, and moray eels.
In the Rio de Janeiro region, just a short boat ride from the mainland, Ilha Grande is a tropical paradise. This island is not only known for its breathtaking landscapes but also for its great snorkeling opportunities.
Lagoa Azul and Lagoa Verde are particularly popular locations on Ilha Grande, with their calm waters ideal for spotting fish, green sea turtles, starfish, and even the occasional seahorse.
Beyond the ocean, Brazil’s freshwater rivers also provide incredible snorkeling experiences. Rio da Prata, located in the Bonito region, is famous for its crystal-clear waters, which allow for exceptional visibility.
Snorkelers can glide along the gentle current while observing a variety of fish species and lush aquatic plants. The vibrant colors and serene environment make this an enchanting spot for nature lovers.
Another breathtaking freshwater spot is the Sucuri River, often hailed as one of the most beautiful in Brazil. The river’s clear waters and abundant wildlife create a mesmerizing snorkeling experience.
While snorkeling in Brazil’s coastal waters and islands, you can encounter an array of marine life that includes many species commonly found in the Caribbean.
Frequently spotted fish at snorkeling depths include the French angelfish, the three-banded butterflyfish, and the Caribbean sergeant major, as well as surgeonfish, morays, flying gurnards, and even sea horses. Green sea turtles are common at certain locations, in particular around Ilha Grande.
In Brazil’s freshwater rivers, such as Rio da Prata and Sucuri, the underwater ecosystem is equally captivating. As you snorkel through the rivers, you’ll be greeted by schools of Piraputanga, a silver fish with a red tail that can reach 24 inches (60 centimeters) in length.
Pacus, brightly colored tetras, catfish, as well as the Freshwater Dorado are also easy to spot. You may also be lucky enough to encounter a small Smooth Fronted Caimans, locally known as Jacare.
The best time to go snorkeling in Brazil typically falls between December and March. During these months, the weather is warm, and water visibility is at its peak, especially in locations like the northeastern coast (Maragogi and Porto de Galinhas) and Ilha Grande.
This period also coincides with the dry season, resulting in calmer seas and more enjoyable snorkeling conditions. In contrast, the cooler months from June to September can still offer good snorkeling opportunities, but visibility may be reduced due to winds and rain, particularly in the southern regions.
