The Costa Rican magic mushroom is another favorite from the Central America region. This beautiful Psilocybe cubensis variety was found in the foothills surrounding Arenal Volcano, Costa Rica, at approximately 1000 to 1200 feet of elevation. Costa Rican Mushroom (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. Legend has it that they have been used by the local indigenous people since the beginning of time. Costa Rica is a magical lush kingdom and we are glad to have a sacred mushroom from this region of the world.
