Created on the 30th January 1971, one of the oldest and most famous in Costa Rica located 37 Km to the north of Alajuela. The indigenous name of the Poás Volcano was Chibuzú. The Spanish gave the name Botos or Votos; a reference to a tribe that inhabited the plains between San Carlos and Sarapiquí and that fled when the colonizers arrived. Nevertheless this name was not used again until the middle of the XIX century and in its place the volcano began to be called Poás or Púas, today San Pedro de Poás. The main attraction of the Poás Volcano is that it has remained active since before the first official registers in 1928.  There are three main periods of activity: from 1888 to 1895, from 1903 to 1912, from 1952 to 1954. At present its eruptions vary in intensity and levels of danger.
