Rickarton Woods, near Stonehaven, has become the venue for a number of unauthorised gatherings, which are now causing a headache for the landowner.
The woodland, a popular spot for dog walkers, is part of the Rickarton Estate but the public has been given free access to the land under the Right to Roam scheme.
Owner Richard Holman-Baird said he welcomed its use by those wanting to enjoy the countryside but was now saddled with a big clean-up operation he has "neither the time nor resources for."
"We are not getting paid to offer public access - there is no recompense from our point of view," he said.
"Our backs are against the wall with farming the way it is just now and this is an extra pressure we could do without.
"It's not them having a party that is the problem. It is the mess left behind. It's not fair for other people who use this land to have to put up with the debris and I don't have the time or resources to go running around clearing it up.
"We've taken all the stock of the land to make it as user friendly as we can for dog walkers and want to encourage that but we can't have this situation every week."
Stonehaven resident Michelle Morton, who uses the area regularly discovered the mess and contacted Aberdeenshire Council. She said someone was sent to investigate but told her they could not take action because it is private land.
"They left a mass of debris behind with broken bottles, cans and food papers and a copious amount of alcohol," she added.
"It looked like a rubbish dump. I collected as much as I could and took it to the recycling centre and put the rest into one of the tents left behind
"It's a lovely place to walk your dogs safely and it would be a shame to lose it."
Mrs Morton said she was now concerned that it could become a popular haunt for teenagers, and "a second Skatie Shore".
"It is a privilege that we are allowed to use the woodland. It doesn't seem right that a landowner who makes every effort to open up this area for public use should be stuck clearing up after those few who abuse it," she added
"Quite a few of the teenagers were seen being picked up by parents and I hope this may strike a chord with them and that they will make sure their children have cleared up before leaving."
