A Nightclub

A portion of Hotel Las Cuevas in Trinidad, Cuba, Disco Ayala gives you a chance to encounter a rave in a cavern. With three bars and five move floors, the club impacts disco-salsa music from a DJ stall while hued lights play off the stalactites on the walls.

At the point when the explorers got inside, they likewise discovered a few openings to the outside around the floor of the cave. However, the researchers were less astounded by the almost around 13-acre size of the cavern than by the mists that darkened their view of the ceiling in what is known as Cloud Ladder Hall.
