Discover one of Ilha Grande's most astonishing natural phenomena on a boat cruise that combines adventure, crystal-clear waters and paradisiacal landscapes. The Acaiá Grotto itinerary takes you to special places on the island, with stops for swimming, contemplation, and direct contact with nature.

Gruta do Acaiá — a hidden natural spectacle

The highlight of the tour is the Acaiá Cave, known for the stunning turquoise-blue effect created by sunlight passing through the seawater and illuminating its rocky interior. Located below sea level, this natural formation offers a stunning visual experience, as if the water were emitting its own glow.

Access to the cave is through a narrow, low passageway, with sections that require caution and mobility. Therefore, it's important to be prepared for challenging access and to follow local guidelines. The visit is worth it for the opportunity to see one of Ilha Grande's most intriguing and unique landscapes up close.

Lagoa Azul — a natural aquarium

With transparent waters in shades of blue, the Blue Lagoon is perfect for swimming, floating, and watching the fish. Take advantage of the stop to snorkel, relax in the water, and admire the marine life at one of the region's most famous postcard-worthy spots.

Green Lagoon — nature and marine life

Lagoa Verde captivates with its shallow, greenish waters, ideal for swimming and snorkelling. Explore the marine environment and keep an eye out for fish and turtles amid the unspoiled beauty of Ilha Grande's coastline.

Grumixama — a haven of tranquility

Less frequented by some itineraries, Grumixama offers a welcoming atmosphere, calm waters and a landscape surrounded by vegetation. It's the ideal place to slow down, relax and enjoy the serenity of nature.
