The valley lies at the back of Bellozanne and planting was carried out last year to commemorate the 60th anniversary of the Island’s Liberation in 1945.
The work was finished in December and National Trust lands manager John Horn said they now hoped to install a wooden viewing platform overlooking the area.
A planning application has been made asking permission for the structure to be installed to the west of the valley.
Mr Horn said: ‘There are quite a few wooden structures in the form of bridges and boardwalks across streams and muddy ground.
‘The final thing we plan to put in that area is a viewing platform which will overlook the Liberation woods.
There will also be an interpretation panel on the platform which tells about the wildlife in the area.’ Mr Horn said viewers would be high up, overlooking the woods, and might be able to see jays in the trees and catch a glimpse of the purple hairstreak butterfly, as well as take a look at the flora and fauna.
He said he got his inspiration for the half-hexagon platform from a visit to St Helier’s twin town in Germany, Bad Wurzach.
