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.

With calm beaches, clear waters, and an unspeakable beauty, the archipelago of Berlengas is the perfect day trip from Peniche.  Located approximately 7 miles away from Cape Carvoeiro, in Peniche, the archipelago consists of 3 island groups: Berlenga Grande, Estelas and Farilhões-Forcadas. The archipelago is also considered part UNESCO's World Network of Biosphere Reserves. The ferry will take you from Peniche to Berlengas, where you will be able to enjoy and explore the island on your own. You will have close to 4 hours to explore the archipelago before boarding the return ferry to the starting point.

Enjoy the beauty of the natural reserve that includes the island of Berlenga Grande that has been protected by the Portuguese government since 1465 and was declared a Biosphere Reserve by UNESCO.

Travel to Berlenga Grande on a comfortable boat to explore some trails with an expert guide before heading to some dramatic sea caves by boat. Next, go to the Fort of S. João Baptista, which defended the seafarers of this archipelago for centuries. Be dazzled by the crystalline and wild waters and by the natural beauty of this remote place on the Portuguese coast before heading back to Lisbon.

The Berlengas archipelago is situated 16km west of Peniche, a powerful granite block which belongs to the parish of St. Peter, in the Peniche municipality. The archipelago is a protected area that includes various nature reserves and is considered a UNESCO Biosphere Reserve since 2011. Depart from the harbor of Peniche and enjoy a 30-minute ferry ride along the turquoise sea waters. Arrive at the Berlengas harbor from where you will be able to freely explore the archipelago.
