About 700 people attended an illegal rave over the weekend, police said.
Kent officers said the rave started on Saturday at Kingswood and wound down at about 1000 GMT on Sunday, with the last people leaving the site that evening.
Police said they attended the area every 90 minutes during the event. Some youths were reported as loitering but caused no problems, said a spokesman.
Organisers tidied the site, while parked vehicles led to problems but were passable with care, police said.
A spokesman said a group of up to 15 youths were reported to be loitering in a pub car park on Sunday morning, but officers found they were using the area as a meeting point.
He said the site owner and residents were satisfied at the way the police handled the situation.
