Arenal Volcano Magic Mushrooms a.k.a. Costa Rican Magic Mushrooms (Psilocybe Cubensis Costa Rica) is a strain found in the foothills surrounding the Arenal Volcano in Costa Rica. These mushrooms grow naturally in the wild and love warm, humid tropical climate and grow at 1000-1200 ft. above sea-level. These sacred mushrooms have been growing at the base of a highly active 7000-year-old volcano for many millennia and have been storied to be used by the local indigenous people since the beginning of time.
