Furna do Frei Matias is a natural lava cave on the northwestern slopes of Pico Mountain, in the rural uplands of Madalena municipality, Pico Island, Azores, Portugal. Its entrance has no numbered street address; use coordinates 38.494843, -28.448119 to identify the location. Created by volcanic activity rather than human construction, the cave attracts travelers interested in lava-tube geology, rough underground terrain, and Pico’s quieter agricultural landscapes. Its name recalls a local tradition associating the cave with a religious recluse, Frei Matias.
What to Expect at Furna do Frei Matias
This is a countryside cave, not a developed underground attraction with illuminated galleries and paved visitor routes. The principal experience is the contrast between green surface vegetation and dark volcanic rock. Lava tubes form when the outside of a flowing lava stream cools and hardens while molten material continues moving beneath it; drainage can leave an underground passage. At Furna do Frei Matias, that volcanic origin explains the irregular walls, uneven floor, and enclosed spaces.
Approach the entrance slowly and assess conditions before stepping underground. Daylight falls away rapidly, and wet rock can be slippery even when the weather outside seems settled. A short look around the entrance is a different undertaking from exploring deeper passages: the latter requires suitable equipment, experience, and preferably a knowledgeable local guide. Do not treat a phone flashlight as your main light, and never assume that a passage continues safely simply because someone else has entered it.
- Natural lava passage: The cave reveals the underground spaces left behind by moving and cooling basaltic lava.
- Entrance vegetation: Green growth around the opening provides a striking contrast with the dark interior.
- Volcanic textures: Examine irregular rock surfaces without touching fragile projections or removing material.
- Upland setting: Surrounding pastureland places the cave within Pico’s working rural landscape rather than a resort district.
- Local folklore: The association with Frei Matias adds a human story to a formation whose origins are geological.

Visiting Tips, Getting There & Nearby Pairings
Choose a dry, clear morning, allowing time to find the rural approach and return before dusk. Save the coordinates offline: navigating only by the attraction name can be less useful among agricultural tracks. A rental car or prearranged taxi is more practical than public transport; arrange your return pickup beforehand. Do not assume every mapped track is suitable for a standard rental vehicle. Leave farm gates as found, avoid blocking machinery, and carry water, sturdy footwear, a headlamp, and backup lighting.
The rough approach and natural cave floor are unsuitable for wheelchair or stroller access; this is not a step-free sightseeing route. There are no formal rest areas to structure a visit around. For a short walk, concentrate on the entrance vegetation, surrounding pasture scenery, and nearby volcanic outcrops where access is permitted. Major attractions are driving pairings, not five-to-fifteen-minute walks: consider the interpreted lava-tube experience at Gruta das Torres or Madalena’s waterfront. Keep clear of livestock and respect private land.
Frequently Asked Questions
What are the opening hours and best visiting time?
The location is listed as accessible around the clock, but this does not mean it is staffed or illuminated. Visit during daylight, preferably in dry weather, and abandon the approach if visibility or footing deteriorates.
Do you need tickets or reservations?
An independent visit is free, without a conventional timed-entry ticket. Arrange any guided underground exploration separately and check equipment requirements before committing to a departure.
How much time should you allow?
Allow approximately 30–60 minutes for finding the approach, viewing the entrance, and returning to your vehicle. Deeper exploration is a separate activity whose duration should be agreed with a suitably experienced guide.
Is Furna do Frei Matias suitable for children?
Older children accustomed to rough outdoor terrain may enjoy an entrance-area visit with close adult supervision. Darkness, slippery surfaces, and uneven footing make underground exploration unsuitable as a casual family walk; keep young children away from drops and unstable edges.
When planning your Azores travel guide or browsing verified attractions in Azores, pair this stop with standout local spots including Cascata da Ponta do Arnel, Pousada Forte da Horta, Miradouro da Boca do Inferno, and Whaling Industry Museum (11.6 km away).
