📍 Gruta do Natal Auf Terceira gibt es zwei Höhlen, nur 10 Minuten mit dem Auto voneinander entfernt, die man besichtigen kann. Dies ist die Gruta do Natal. Am Eingang bekommt man einen Helm, den man auch wirklich gebrauchen kann. Durch die kleinen Gänge haben wir uns paar mal den Kopf gestoßen.

Reviews Summary

Visitors find Gruta do Natal to be a very cool and fascinating natural lava tube with unique geological features. The short visit duration and the option for a combo pass with the nearby volcano are highly praised. Some caution that it can be tight in spots and not recommended for those with severe claustrophobia due to its one-way path.

"Very cool cave formed from lava flow and explosions. We toured with our guide from Green Generation and it was awesome and we learned a lot beyond what was presented on the small placards throughout. Its formation is fascinating and to think you’re so close to the beautiful lake right above it is very neat. Gets a little tight in spots but only for a moment, we really enjoyed our visit."

J K

"Would defo recommend — very cool place! This highlight will take you about 30 minutes max, including time to read everything and take photos.

I’d also recommend doing the hike (Mistérios Negros) right next to it afterwards — absolutely unreal views!"

Leal

"Wonderful trek! An easy start, an eazy end and nicely uneasy midpart 😊 Lava paths are lavaly 😂"

Tailored advice for your travel style

👨‍👩‍👧 Families with Kids

Gruta do Natal can be an exciting adventure for families, offering a unique glimpse into volcanic geology. The provided helmets add a fun, explorer-like element for children. However, parents should be mindful that some passages are quite narrow and the cave has a one-way system in parts, which might be challenging for very young or anxious children. Reddit

In-depth insights and expert knowledge

The Geology of Gruta do Natal

Gruta do Natal is a remarkable example of a lava tube, a natural tunnel formed by flowing lava. Its creation is a testament to the volcanic forces that shaped Terceira Island. The cave's interior showcases a variety of unique geological formations, sculpted by the cooling and solidification of lava, as well as subsequent geological processes. These formations offer a glimpse into the island's fiery past. Reddit

Visitors often remark on the fascinating formation of the cave, noting how it feels to be so close to the beautiful lake situated directly above it. This proximity highlights the dynamic interplay between subterranean and surface water systems on the island. The cave's structure, with its varying widths and heights, provides an immersive experience into the earth's crust. Reddit

It's important to remember that the cave's formation means the rock can be unforgiving. The hard hat provided is essential, as the ceiling is low in many sections, and it's easy to bump your head. This feature, while requiring caution, also adds to the authentic caving experience. Reddit

Navigating the Cave: Tips for a Smooth Visit

When visiting Gruta do Natal, wearing the provided helmet is non-negotiable. The cave's passages can be surprisingly narrow, and the rough volcanic rock ceiling is at a low height in many areas. Bumping your head is a common, albeit avoidable, mishap if you forgo the helmet. Instagram

The cave operates on a one-way path for a significant portion of its length. This means you cannot easily turn back if you feel uncomfortable or decide you want to re-examine a particular formation. If you have significant issues with tight or enclosed spaces, this aspect of the visit might be challenging. Reddit

Despite these considerations, the experience is generally described as a wonderful trek with an easy start and end, and a nicely 'uneasy' middle part that adds to the adventure. The entire visit, including reading the informational placards and taking photos, typically takes around 30 minutes, making it an efficient yet memorable exploration. Reddit
