Puerto Rico is an island, which contains beautiful beaches and it is called "The Enchanted Isle", but it is actually a hotbed of UFO sightings and alien abduction experiences. The island has been a U.S. territory for over 114 years and its inhabitants are American citizens. As such, there are many U.S. military installations throughout the island. Most UFO sightings and alien abductions occur near these installations and U.S. government owned lands. One of the most notable places is "El Yunque Rainforest" which lies on the east coast of the island. El Yunque is the only tropical rainforest in the United States National Forest System. Could there be an extraterrestrial base in El Yunque rainforest? Well, many Puerto Rican and U.S. ufologists think there is.
El Yunque rainforest is a tourist attraction, where they come from all over the world to witness the exotic vegetation and flora and fauna. Although there is no vicious wild animal they should worry about, there are in fact many UFO sightings and alien abductions. This rainforest is where many tourists get lost for days and come back with incredible stories of alien abductions. 
The first chupacabra sightings occurred in municipalities surrounding El Yunque rainforest. Could the chupacabra be an experiment gone wrong and then escaped from a U.S. experimental facility in the rainforest? Although this writer, along with most ufologists, believes that this creature is an extraterrestrial beast, some investigators on the island believe that it is only an experiment gone wrong by the U.S. government and NOT an extraterrestrial. EL Yunque is also the oldest Forest Reserve in the Western Hemisphere. In 1876 King Alfonso XII of Spain set aside 12,000 cuerdas (1 cuerda =.9 acres of land) to be protected for all times.
Puerto Rico is one of the three points of the Bermuda Triangle and is where the chupacabra sightings originated which eventually spread around the world. Moreover, the island is also home to the largest radio telescope in the world. But the reason why these events are occurring is also because of location. The island is almost isolated from the rest of the Caribbean, being the easternmost of the Greater Antilles islands, sticking out into the Atlantic Ocean. This strategic location is one of the reasons why the United States has kept military bases on the island after all these years.
The Puerto Rico Trench, which lies along the northern coast of the island, is the deepest part of the Atlantic Ocean and this could be the reason why there are many USO (Unidentified Submerged Objects) observed by many people and tourists entering and exiting the waters around the island and along the beautiful beaches. Could there also be an extraterrestrial base somewhere in the Atlantic Ocean and/or deep inside the Puerto Rico Trench? The Bermuda Triangle, where many ships and planes have disappeared over the years, covers a large span of the Atlantic Ocean and Puerto Rico being the southernmost point of the Bermuda Triangle has experienced one of the most frequent UFO sightings and alien abductions in the world despite being a small island.
