Berlenga Islands: A Journey into Portugal’s Wild Atlantic Heritage
Off the windswept shores of Peniche lies a world apart the Berlengas Islands, a cluster of granite rocks rising sharply from the Atlantic Ocean. Despite their rugged appearance, these islands are full of stories, life, and awe-inspiring beauty. Officially known as the Berlengas Natural Reserve, this protected area has been attracting adventurers, historians and nature lovers for centuries, and it remains one of Portugal’s best-kept secrets.
From Monks to Military: The Human Story of the Berlengas
Though seemingly remote, the Berlengas have been intertwined with human history since at least the 15th century. It was here that monks from the Order of Saint Jerome built a modest monastery to shelter shipwrecked sailors and offer spiritual refuge in the middle of the ocean’s chaos. Life on the island, however, proved too harsh and was eventually abandoned but remnants of that era still remain, whispering stories of faith and resilience.
Later, the Portuguese Crown recognized the island’s strategic value. In the 17th century, the striking Fort of São João Baptista was built using the stones of the ruined monastery. Perched dramatically on the rocks and connected to the island by a narrow causeway, the fort was designed to guard the coast from pirates and invaders. Today, it stands as one of the most iconic examples of coastal military architecture in Portugal and is a must-see for visitors.
A Protected Sanctuary of Wildlife and Raw Beauty
The Berlengas are more than just a historical curiosity – they are a haven of biodiversity. In 2011, the archipelago was designated a UNESCO Biosphere Reserve, in recognition of its ecological importance. Berlenga Grande, the largest island and the only one accessible to the public, is home to unique flora and a wide variety of seabirds.
Rare species like Cory’s shearwater nest in the cliffs, while beneath the surface, the crystal-clear waters reveal an entire world of marine life. This makes the islands a paradise for snorkelling, diving, and kayaking. The famous Gruta Azul (Blue Cave) is especially popular for boat tours when the sun hits the water just right, the entire cave glows in hues of sapphire and turquoise.
UNESCO Biosphere Reserve: Nature at Its Wildest
In 2011, the Berlengas were designated a UNESCO Biosphere Reserve, acknowledging their critical role in marine and bird conservation. While only Berlenga Grande is open to the public, the archipelago is a sanctuary for rare species both above and below water.
Among the rocky crevices, you might spot the Cory’s shearwater, a seabird that nests exclusively in undisturbed habitats. Underwater, divers and snorkellers can explore vibrant reefs teeming with octopuses, crustaceans, and schools of Atlantic fish. The surrounding waters are part of a marine reserve, offering pristine conditions for eco-tourism.
Planning Your Trip: When and How to Visit
The best time to visit the Berlengas is between May and October, when sea conditions are most favourable. During this period, ferries and fast boats run daily from the Peniche marina, with travel times averaging around 30 to 45 minutes depending on the boat.

Day trips are the most popular, but there is also a small eco-camping area and even the option to stay overnight at the fort a truly unique experience for those seeking silence and starlight.
What to See and Do on the Island

Along the trail, you’ll encounter the Fort of São João Baptista, birdwatching spots, and interpretive signage about the island’s delicate ecosystem.
No trip is complete without a boat ride to the (Gruta Azul) the Blue Cave. When the sunlight enters the cave at just the right angle, it sets the water aglow in brilliant shades of turquoise and sapphire. It’s one of the most mesmerizing natural sights in Portugal and a favorite for kayaking and boat tours.
There’s also a small interpretation centre, a seasonal restaurant, and a few basic facilities. But don’t expect luxuries part of the Berlengas’ charm is how raw and untouched they feel. Bring water, sun protection and comfortable walking shoes, and embrace the minimalist beauty of the landscape.
