One of the most memorable experiences of a visit to the Berlenga Island happens around the island, where the sea has carved over millennia a spectacular scenery of caves, tunnels and stone arches. Discovering the Berlenga caves by boat is, for many, the highlight of the trip.
What are the Berlenga caves?
The caves result from the erosion of the waves on the island’s rocks, creating cavities, tunnels and passages where the water takes on intense shades of blue and turquoise. Some are only accessible by sea, in small boats, which makes the visit even more exclusive.
The Furado Grande and the Cova do Sonho
The Furado Grande is the most famous cave on the Berlenga: a long natural tunnel that crosses the rock and opens into a small cove of calm, crystal-clear waters, the Cova do Sonho. Crossing it by boat, with the light coming in from both ends, is one of the images that most stays with those who visit the island.
The Blue Grotto
The Blue Grotto owes its name to the reflection of the light passing through the water and lighting the interior with a deep, almost unreal blue. It is one of the most photographed corners of the Berlenga.
How to visit the caves
The caves are visited on a boat tour around the island. Several BerlengaTur packs include the cave circuit, with the boat entering the accessible passages and approaching the arches and tunnels. It is an experience suitable for all ages.
Tips for visiting the caves
The caves are only one part of the experience. Discover everything about what to do on the Berlenga Island during your stay.
- Keep your camera or phone well secured — the contrasts of light and colour are stunning.
- On days with rougher seas, access to some caves may be restricted for safety.
- Choose a pack that includes the cave circuit.
How much does it cost to visit the caves?
Pack 2 (35€) includes the crossing and the cave visit; Pack 3 (40€) adds a guided tour of the island; Pack 4 (45€) also includes snorkelling in the waters of the Nature Reserve. The BerlengaPass (ICNF fee) costs 3€ per person aged 18–65, 1.50€ for ages 6–18 and over 65, and is free for children under 6 (who must still register). It is mandatory for all visitors and must be booked in advance.
Best time to visit the caves
The Berlenga caves can be visited from April to October, when the sea is calmer and underwater visibility is greater. In July and August places are limited — book at least 1 to 2 weeks in advance to secure your spot. Outside this period, weather conditions may prevent access to the caves even with a boat available, so we always recommend confirming before departure.
What to bring for the cave visit
Bring footwear that can get wet (you leave the boat for the caves over the rocks), clothes you don’t mind getting dirty, sunscreen and enough water for the day. If you go on Pack 4, the snorkelling equipment is included.
Frequently asked questions
Do I need to know how to swim to see the caves? No. The caves are visited by boat; you don’t need to get into the water.
Do all tours include the caves? Not all. Check your chosen pack — several include the full cave circuit.
