Sa Nurre de su Hoda is a cave with walls over 100 metres high – every spring and summer around noon, a great ray of light lights up the entire cave with a peculiar blue light.
Every year a concert takes place, mixing hiking and internationally renowned jazz players who start performing just as this phenomenon occurs.
The cave is accessible only a few months a year, from May till August, and booking with local guides is required. The concert has limited places to preserve the natural cave system.
