What Travellers Say
Reviews Summary
Visitors are consistently awestruck by the immense scale and unique geological formation of Algar do Carvão, often describing it as a must-see on Terceira Island. The sight of the volcanic chimney and the greenery above is frequently highlighted as breathtaking. However, some feel the built-up infrastructure has detracted from its natural, adventurous feel, and photography can be challenging due to the lighting.
"The cave is huge and the place is really exceptional. The only bad thing is that everything has been built inside making it lose its natural charm."
Ana Moura
"I couldn’t believe how big this place is. You can feel the amount of power the lava had to form this tube. It is gorgeous looking up to the greenery near the top with the light shining through! I’ve never seen anything like it!"
Summer
"If you like caves and exploring them, this is a must-see in Terceira! This used to be a volcano vent that is right smack in the centre of the island and houses a lot of current flora within the cave. The descent is clearly paved with stairs and goes 45m downwards… there are further stairs that are barred that go down a steeper incline into a clear pond of water. It seems that the pond was once accessible to tourists but no longer. The cave is only open 230-5pm and is 10 euros to enter pp. you can pay 15 euros and see a second smaller cave called gruto do naval that is nearby (need to drive to that site).
This cave is honestly not that big and while there is lighting to minimize tripping and falling, it is difficult to take good photos once inside of it. It is a little chilly and damp inside the cave and i wore a windbreaker and long leggings… but I also see other people wearing t shirts and shorts….
This cave has been commercialized and for those looking for a more “adventurous” and explorative cave au natural, you will be disappointed."

For Different Travelers
Tailored advice for your travel style
👨👩👧 Families with Kids
While the cave itself is the main attraction, consider combining the visit with a picnic lunch at a scenic spot nearby. The experience is relatively short, making it suitable for younger attention spans. Ensure children wear comfortable, closed-toe shoes for the descent and ascent. The unique environment provides a memorable experience that goes beyond typical tourist attractions.
🚶 Budget Travelers

Exploring the Volcanic Wonder
Visitors often remark on the feeling of being inside a dormant volcano. The crystal-clear pond at the deepest point adds to the mystique, though access to it is now restricted. While the cave has been enhanced with lighted stairways for accessibility, some visitors feel this has slightly diminished its raw, natural charm. However, the opportunity to witness such a powerful geological phenomenon up close is undeniable. It's a place that sparks wonder about the forces that shaped our planet.
For those interested in geology or simply seeking a unique natural wonder, Algar do Carvão is a must-visit.

Remember to wear appropriate clothing and footwear to fully enjoy the cool, damp environment and the descent into the earth.
Photography Tips for the Cave
Experiment with different angles to convey the immense scale of the volcanic chimney. Focus on the interplay between the natural rock formations, the man-made stairways, and the vibrant green of the plants clinging to the walls. The crystal pond at the bottom, though no longer directly accessible, can still be a compelling subject if visible. Be patient; sometimes waiting for the light to shift can yield a more dramatic photograph. While phone cameras can capture the scene, a DSLR or mirrorless camera with a wide-angle lens will offer more flexibility and better results.
