A police chief says he has a clear message for anyone bent on causing trouble in Kelvingrove Park - stay away.
Inspector Eddie Seery says police will be stepping up patrols as the school term ends.
Drinking alcohol in Glasgow's public places and parks is outlawed.
But groups of youngsters have been traveling from across the central belt to 'party in the park'.
Sporadic hot spells this year have been marred by drink-fuelled trouble and anti-social behaviour.
On Wednesday, a 17-year-old boy was left seriously injured after he was attacked.
Two teenagers, aged 15 an 18, and a man, 33, have been arrested.
Insp Seery said full resources would be on show - to help make the point.
"We will persevere with this for as long as it takes.
"We are trying to get the message out there through social media that this is not a party park.
"It is a park that has legitimate use, and if you want to come and use by all means come and use it.
"But if you have come here just to be a nuisance then think again, because the police and the council will use all tactics and legislation that's available to them."
He accepts that this level of response is not sustainable in the long term.
The authorities are currently looking at a raft of other measures.
"Certainly we are working closely with the council and there are several different long-term plans being looked at like allowing the grass on the hill to grow to become more of a meadow to try and discourage groups congregating.
"The council are putting up better signage in relation to park rules - and highlighting them on social media."
Visitors to the park can expect a heavy police presence Friday.

Some of the resources are specialist resources.
Insp Seery said: "I will have mounted (police) here Friday, and I also have off-road cycles and off-road motorbikes.
"They can move around the park's paths a lot easier and a lot quicker than ourselves."
The inspector reassured Glasgow's residents and visitors to the park.
"What we are doing is having an effect.
"We are here, we are aware and we working very very closely with the council to make sure than any incidents are dealt with at source immediately or they are responded to in a very, very quick time.
"By the high-visible presence we are hoping that it will deter certain people from coming and creating issues."
