This was another spot that several people suggested that we visit.
These caves were totally amazing. They have recently installed LED lights and this was such a magical touch. There were several lakes in the caves, these were also lit up with this gentle lighting and the water was crystal clear.
We took the tour, it led us through the caves and ended at Lake Martel. Everyone was seated in what was the coolest underground auditorium.
Three rowboats sailed into the lake, one held a little band. They played classical music, and the acoustics were unique down there, it was a beautiful experience. Check this place out if you are in Mallorca.
