Wiltshire Police said the summer Solstice gatherings at Avebury and Stonehenge proved to be very positive and peaceful events.
About 1,500 people attended at Avebury, and there were three arrests, two for drugs-related offences and one for a public order offence.
At Stonehenge more than 34,000 people attended the celebrations and there were 25 arrests.
Superintendent Gavin Williams said: “We are pleased that the Solstice celebrations at Stonehenge and Avebury have been enjoyable events for the majority of people attending.
"There were 25 arrests at Stonehenge and three at Avebury, which were mainly for drug- related offences.
“The road system worked well with minimum delays and many people used the public transport as we advised people to do.
"Every year there are new challenges for us at Solstice but it is always a pleasure to see so many people enjoying the event.
“This year we estimate 36,000 people visited the stones throughout the night.
"There is always a small proportion of people who will try to break the law but I am satisfied that this was a successful policing operation and Wiltshire Police continue to facilitate a safe Solstice with our partners.’
