Pro-hunt campaigners are planning to have 1,000 demonstrators a day in Brighton during next month's Labour Party conference.
In a statement today the Countryside Alliance warned the demonstrations would be "high-profile" throughout the conference week, September 24 to 28.
"Each procession will be accompanied by a representative contingent of 1,000 rural campaigners from a different region of the country.
"These events are designed to put and keep the growing frustration and anger of the rural people firmly front-of-mind amongst governments, its advisers and politicians in the lead up to the proposed Government's Bill on hunting, around the turn of the year, and beyond to the next general election."
The pro-hunt campaigners recently were warned to stay away from the Brighton conference.
Hove MP Ivor Caplin urged Countryside Alliance members to keep their "disruptive and unpopular" protests away from the conference.
He said: "There is no place for the hunt campaigners at this year's conference. They are not welcome. If they are really serious about their campaign they could stand a parliamentary candidate in Hove and Portslade."
Anti-capitalists are also threatening to demonstrate during the conference and Sussex Police have cancelled all leave for the week.
Hundreds of pro-hunt demonstrators turned up last month at Brighton and Hove Sixth Form College in Dyke Road, Brighton, where Prime Minister Tony Blair was appearing on the BBC's Question Time programme.
As Mr Blair's Jaguar pulled into a college gate, demonstrators surged forward, pushing police officers out of their way.
Others followed as they tried to force through the gate, screaming abuse, sounding klaxons and waving banners.
