'Thoughtless' sledgers left Burton Dassett Country Park in a mess following the recent snow.
And fears have been raised that some of the objects they left - including broken plastic and metal sheets - could pose a danger to wildlife and people.
Senior ranger Craig Earl is one of four people responsible for looking after the area.
He sa
id: "This happens every time there is a period of snow.
"Everyone turns out with a whole range of homemade sledges and a lot of them don't bother to take them away.
As soon as the thaw comes along, we are left with the onerous job of clearing it up."
Mr Earl said items which have been used as sledges and discarded include tea trays, dinghys, car windscreens and sheets of metal.
He said: "It is not really possible to stop it because of the open nature of the site.
"We always try, through use of our website and signage, to educate people on how to use the site safely.
"But a lot of the people who are prepared to use reckless objects as sledges are unfortunately not the kind of people who tend to worry about anyone else's safety."
He added: "We don't want to spoil anyone's fun - we can totally understand the appeal of sledging here, but people need to apply some common sense and consideration for the safety of themselves and other people.
"It is not a quick job to clear up all the mess and it takes us away from other important tasks."
Burton Dassett resident Christine Compton said: "Worse still are the thousands of shards of sharp plastic still scattering the hills, which could cause serious injury to animals and people."
