What Travellers Say
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."

"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!"

The Geology of Gruta do Natal
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.
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.
Navigating the Cave: Tips for a Smooth Visit

If you have significant issues with tight or enclosed spaces, this aspect of the visit might be challenging.
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.
