Proposals which could see a county's country parks transferred to a heritage trust or even sold off are being discussed by councillors.
Suffolk County Council is reviewing the running of its three country parks - Brandon, Clare Castle and Knettishall Heath - and 25 other smaller sites.
The parks, which cost about £330,000 a year to run, could be transferred to district councils or to a trust.
At a meeting next week the council will also look at whether to sell its parks.
A report to the council's environment scrutiny committee, which meets on 12 September, said it could continue to manage the sites but this would "seem to be out of line" with council policy to commission services from outside groups.
The report said the county has "no statutory duty to provide sites", but it has a role in helping people enjoy the countryside in the county.
It said many of the sites are valued by local communities and there would be "great public concern" if these were sold off.
The report said more discussions are needed with district councils and other organisations before any final decisions can be made.
