A total of 21 people have been charged with irresponsible camping and environmental damage on the first weekend since travel restrictions eased.
Despite the wet weather, campers left significant amounts of litter, including large items of camping equipment such as chairs and sleeping bags, broken glass and full bin bags of rubbish at Loch Lomond & The Trossachs National Park.
Irreparable fire damage to trees and ground in the area was also reported.
At one site, a total of 19 bags of litter were collected and ten at another.
Further to this, a tree was so badly damaged at another location by fire it may need to be felled.
This happened in spite of national guidance asking people not to go camping until July 15.
