be psychedelic open air is a multi-day outdoor psytrance gathering held at a site near a lake in the kaszuby region of northern poland. the event runs across three days with programming spread through friday, saturday, and sunday, drawing a roster of djs and live acts from within the polish psytrance and goa scene. decoration is handled by modern shamanism decorations, propsy, and psylot art, with the be psychedelic collective itself also contributing visually.

the event has a clear regional identity, with a number of acts on the lineup tied to gdańsk, gdynia, sopot, and other northern polish cities. past editions have run at the same stężyca location, establishing it as a recurring fixture for the local and broader polish psy community.
