a psychedelic music and art festival running annually since 2010, previously known as cosmic frog festival, and now one of the larger events of its kind in the czech scene. it takes place over five days at a woodland and lake site in the north-east of the country, drawing a lineup of over 140 artists across four stages.

the bufo stage covers psytrance, hi-tech, darkpsy, forest, and full-on; the groovy stage runs techno, tekno, and house; the chill stage handles psychill and chillout; and the tribal stage hosts live performances and concerts. beyond music, the site includes an art gallery, healing area, psycare, and a dedicated kids area.
