If you've already done the classic Ilha Grande tours and want a different adventure — with a story to tell —, Acaiá Cave deserves a spot on your itinerary. In this guide you'll learn what it is, where it is, how to visit and what to expect from one of the island's most surprising corners.
What is Acaiá Cave?
Acaiá Cave is a seaside stone chamber on Ilha Grande, known for a rare phenomenon: the water there has a blue that seems to glow, an almost fluorescent shade found in very few places in the world. It's an explorer's setting — rustic, cinematic and well off the traditional beach circuit.
Where it is and how to get there
The cave is only accessible by sea: the tour leaves by speedboat from Vila do Abraão. On the way there, the itinerary usually passes some of the island's most beautiful spots, such as Lagoa Azul, Lagoa Verde and Saco do Céu — great for swimming and snorkeling in crystal-clear waters.
What the tour is like
It's an adventure itinerary: besides the stops to swim and snorkel, the highlight is reaching the cave, with its access and glowing blue water. A tour designed for those who want to experience something more memorable than the usual. Discover the Acaiá Cave tour and see what's included.
