Around 50 Hampshire and Ministry of Defence police took action when 250 ravers, many of them teenagers from the Surrey area, attempted to set up a stage and marquee for the event.
They had arrived the night before in a convoy and camped out in a field behind the derelict Spaniard Inn off the A3 in Bramshott, part of which is owned by the Ministry of Defence.
With concerns that unless stopped the numbers could have escalated, Hampshire police warned anybody heading to the rave to stay away and signs were erected on roads to Bramshott.
The initial police operation to disperse the ravers started at 11-30 am on the Saturday morning, just as a marquee and platform were to be erected for the nights event.
A Hampshire police patrol plane was also used to keep the situation under control.
The police later praised the way the youths left the site in a friendly, well-mannered way. Some vehicles and sound equipment were seized, but no arrests had to be made.
It is thought that people heard of the rave via a website, with mobile phone text messages and word of mouth also playing a part.
Assistant chief constable Colin Smith said: "The concern of Hampshire Constabulary and the MoD police is that it was unlicensed, unregulated, uninsured and not governed by health and safety regulations.
"It is not our intention to be spoilsports, but we will not allow these dangerous events on public safety grounds."
After being dispersed the group moved to Painshill in Chobham, Surrey, but Surrey police had been alerted and warned the ravers not to proceed.
They then headed south and reached Brighton in the early hours of Sunday morning, preparing to set up their stage again.
A complaint from a nearby resident alerted the police at 4 am, and by 10 am four police officers arriving in two cars had managed to stop the rave from going any further.
A spokesman for Sussex police said: "The police officers spoke to the organisers and they departed in a good natured and friendly way."
But a handful of protesters pushed two police cars down a hill in Brighton.
The cars were seriously damaged, but no one injured.
One man was arrested for criminal damage and was later released on police bail.
