RUSHCLIFFE Country Park is among a number of Notts sites which have kept their Green Flag status.
A ceremony to celebrate the award was held at the park, in Ruddington. It was attended by those who have worked there over the past 12 months.
Park manager Keith Laing said it was the seventh consecutive year they had made the grade.
Mr Laing, who became manager in 2005, said: "I'm extremely proud.
"The Green Flag Award trains the mind. When you are looking at things on the park you are minded that you have a high standard to maintain."
Mr Laing's team of staff are supported by about 30 volunteers who make up the Friends of Rushcliffe Country Park.
The volunteers received a Queen's Award for Voluntary Services last year in recognition of their work.
Mr Laing, of Cotgrave, said: "The Friends do a lot of conservation work and maintenance tasks, like footpath repairs. We are busy planning our winter work, you can never stand still."
The parkland contains 8km of footpaths, grassland and conservation areas.
It also has a lake, a large children's play area, as well as a skate park and BMX cycle track.
The park is open year-round, with its car park open from 8am to 6pm between April and October, and to 4pm from November to March.
The Friends meet on Wednesdays and Saturdays at 9.30am to carry out maintenance work.
