Last weekend people from around the UK travelled to the Brecon Beacons for a secret rave.
Described as a "free party" the rave was organised by a group called The Psychedelic Way.
The location of the event is a secret but people wishing to attend were told to meet near Storey Arms in the National Park.
Despite the reputation of raves, the rules seemed very strict when it came to the environment. Dogs had to be on a lead because of nearby sheep, no litter was allowed and you had to close gates to stop livestock escaping.
Pictures from the scene show an impressive sound system along with some striking jelllyfish decorations.
Speaking to WalesOnline the organiser said: "It took [us] two days to set up, all we want is for people to enjoy and be free."
Dyfed Powys Police did not respond to requests for comment.
