Reviews Summary

Visitors consistently praise Grotte di Su Mannau for its stunning natural beauty, particularly the underground river and impressive end hall. The geological formations are described as breathtaking. However, some find the English audio guide to be too brief, and the tour can involve a significant wait time.

"This is one of the most beautiful caves I ever visited. Especially the river and the ponds in the middle of the cave are amazing. But also the end hall is very special because of its height. A must visit if you are in the neighborhood however we traveled for more than an hour to visit."

John van Iersel

"A nice attraction to see in the south Sardinia with an amazing staff, keen to explain everything about the history and architecture of the cave"

Davide Fini

"Very impressive cave, great experience. Tours are in Italian language only, but there is an audio guide in several other languages.
The tour is a bit challenging (many stairs, partially slippery, low ceiling in some spots) and I was a bit surprised that we were not equipped with helmets (except from the tour guide ;)"
