Kendal Calling festival organisers say the mud wasn't too bad.
Heavy rain meant some festival-goers sought refuge in nearby hotels but organisers say the mud was manageable.
Ben Robinson's one of the founders of the festival:
Cumbria Police have arrested 36 people for drugs offences at Kendal Calling festival near Penrith. There were fewer than previous years.
16,000 people attended the 9th Kendal Calling festival this weekend. They braved mud and rain to see acts such as Frank Turner and Example.
