Cave of Achaia, Ilha Grande

4.3
Situated between high mountains emerging from the sea is Cave of Achaia, a piece of paradise surrounded by the lush greenery of the Atlantic Forest. This is not a beach ideal for swimming but rather a great place to relax, have dinner, and enjoy a beer or nice caipirinha (a popular Brazilian cocktail made with rum, sugar and lime) while listening to the samba or other Brazilian music being played by the locals. Snorkeling will allow you to explore the small cave with the brilliant light from the ocean illuminating its crevices and to take in the sights of the natural aquarium.

The best way to reach the island is by Angra dos Reis, a two-hour dirve from Rio. From there you can take the hour-long ferry ride across, but keep in mind that the ferry is actually a small boat that carries about 30-40 passengers. You can view the schedule on Ilha Grande’s website, but keep in mind that the boat might not leave at exactly that time. Consider hiring private transport and book them for your return as taxi service does not exist in town. Plan trip to Ilha Grande with our itinerary maker to find out where to go and what to do.

  • Stopped during the boat ride, they take us to visit caves reachable by a wooden ladder. Once inside, the show that is manifested is of a stone inlet, very narrow and not easy to cross: not recommended to those suffering from claustrophobia. Once you reach the bottom it is very nice to dip your head to see a strip of sea green light popping out of a very narrow. However, do not try to overcome it to reach the other side as it is very deep and a current may not allow you a simple ascent.

  • One of the most beautiful places I've ever seen. It is worthwhile for those who come to the Ängra of kings. When I visited the entrance it was out of the cave was the weakness. I don't know how you're doing today. It's been years since I've been in this experience. So much that I have trouble answering the question below.

  • Unique experience. The exit to the sea allows the entrance of a light, which leaves the place with a unique appearance. It's worth knowing!!! Price of 20 reais for the cricket, very friendly and attentive place. I highly recommend the visit

  • Climb five meters down a hole and crawl though a space less than a meter tall and you enter this cave (Gruta). It's a huge space inside, but never tall enough to stand. At the other end, the ocean water enters and pools. Afterwards, go above the Gruta, jump off the rocks, and swim in the watery above the cavern.
  • Magic!
  • A little complicated the descent for those who are claustrophobic. In the end the lighting comes by a gap below and distant.. Looking like an incandescent tape. It's really worth it for being beautiful... I enjoyed it a lot:)

  • One of the most amazing places I've ever met, it doesn't even look real. The narrow path compensates! It is not advised for those who have claustrophobia or fear of darkness.
