Reviews Summary

Visitors find the Furna do Enxofre to be a fascinating and worthwhile experience, especially given its low admission cost. The unique volcanic cave and the tower climb are consistently praised, though some note its small size. The friendly staff and the opportunity to explore additional free 'furnas' add to the positive overall impression.

"Costs 5 euros, the entire thing takes 30 minutes, it was fascinating but small. Still worth the price of admission, you should check out the other furnas on the outside of the tunnel, they are free to explore and there is an altar inside furna de Abel- ask in welcome center for help with directions."
