Anti-dumping signage and CCTV is to be placed in the area
Donegal County Council say over 45 tonnes of waste has been removed from a scenic site at Brinaleck in Gaoth Dobhair.
The clean-up took place last week following an intensive operation by the council and local development group Coiste Forbartha Chnoc Fola.
This operation was undertaken as part of the national Anti-Dumping Initiative.
The Glenties Municipal District was awarded €11,000 under this initiative earlier this year.
After the removal of soil and stone, the waste was removed from the site and this was then taken to an authorised waste facility.
The site has now been landscaped and boulders have been placed along it to stop flytipping in the future.
Michael McGarvey, director of service with Donegal County Council, said: "Anti-dumping signage has been erected and CCTV signage will be erected in the coming days.
"This site will be monitored on an ongoing basis and anyone caught dumping rubbish here will be pursued by the Council".
He says this type of dumping is "a serious blight" on the landscape and the work done by local communities.
Coiste Forbartha Chnoc Fola say they have plans to promote the area as an ideal location for walking enthusiasts.
Donegal County Council says it is an offence to dump rubbish in this way - and anyone who is caught littering or dumping could receive an on the spot fine or a maximum fine of €3,000 if convicted.
