Enjoy a trip to Berlengas Island on a fast boat and visit the caves while looking down through the glass bottom. Admire the outside and inside of different caves, like the Elephant cave, Dream cave, Furado Grande, and more. Afterward, take some time on your own to explore the Island. Walk the beach, gaze up at the lighthouse, discover Forte S. João Batista, and walk the Island's trails.

Meet your guide and board a semi-rigid boat or sports yacht. Head toward Berlengas Island, an eco-haven with a visitor limit, so you can experience its true beauty without the crowds. First, take a short tour around the island and learn all about the different caves, while gazing at the underwater marine life through the glass-bottom boat.

Spot the Elephant cave and feel amazed at the way the natural rock formations resemble the trunk and face of a great elephant. At the dream cave, take in one of nature's masterpieces and learn of its history. Then, at Furado Grande, learn why it translates to Big Hole and how it stretches across the entire island.

Take your time afterward to guide yourself around the Island. Look out over the turquoise waters from the beach. Walk up to the lighthouse and imagine yourself alone. Then understand more of Portugal's history by examining the remains of Forte S. Joao Batista.

Feel free to bring your own snacks, or some extra cash with you to buy them on the Island during the months of May through September.
