Did you know that about 60 of the el yunque rainforest inhabitants are nocturnal and are very seldom seen during the daytime due to strict forestry park hours all guests visiting el yunque must be out of the forest no later than 6pm as of 2014 however one group is permitted each evening to see a side of this rainforest that few have ever seen heard or smelled and it is an experience not to be missed during this tour you will have the opportunity to see flora and fauna scenic views hard
