Guernsey Water says the damage done by Storm Ciaran means the walk will be off limits until the end of January 2024.
The Millennium Walk, otherwise known as the Reservoir Walk, takes in the eastern side of the reservoir and is a popular place for an inland stroll.
But Guernsey Water, who manage the land, says the storm of 2 November uprooted a large number of trees and tore branches off others.
It says it will take some time to clear up and make safe, so the walk will be fenced off until late January 2024.

It's estimated that Guernsey lost around 350 trees during the storm. In its aftermath, Policy and Resources announced that it was giving £15,000 to the Nature Commission, to invest in Guernsey’s public woodland and green spaces.

P&R's deputy Peter Ferbrache says although Guernsey avoided the worst of the storm, its affect on many trees was devastating:
"Our natural environment is part of what makes Guernsey special and I’m very pleased that we can quickly respond by committing to provide this funding.”
