Caverna de los Guácharos
Be sure to visit the Caverna de los Guácharos , a spectacular cave. Cavern after cavern soar high and hollow like great cathedrals. A stream runs through the cave, about 1km long. The entrances are guarded by shrill, shrieking flocks of guácharos , a batlike nocturnal bird. You’ll be given a life vest and be expected to swim part of the way.
