Aug. 24 (UPI) -- Revelers at a music festival in Hungary uncovered a bizarre feature of one specific portable toilet -- it contains a passageway to a secret rave.
A video posted to Facebook by Rave Jungle shows concert-goers at the Sziget Festival in Budapest opening the door to a seemingly innocuous portable toilet in a large grouping of the facilities and traversing the secret hallway to the hidden venue.
"This is why I love Sziget, just open a random toilet and there is a secret party going on," Fabian Ruivenkamp, who also captured video of the toilet passageway, wrote on Facebook.
Ruivenkamp said the hidden rave was kept a secret by festival staff, but he and his friends heard about the cleverly concealed party from other revelers.
This year's Sziget Festival ran from Aug. 9 to Aug. 16.
