(Search for extraterrestrial inteligence), also in (La Parguera) you can visit the fluorescent bay, which you can go in a boat with other people and see thru the glass floor all the sea species that this bay offers during the night, the best night is on a NO MOON, because the moon will reflect in the sea and is not worth it.

Visit El Yunque, this is a rain forest very beautiful and you will feel in heaven, if you go south, you can go to the dry forrest in (Guanica), and go to Giligan's Island, you can take a boat from the Copamarina Hotel Area, there is a lot of signs how to go to Giligan.
