The route through parkland at Croome Court, near Pershore, was built by the 6th Earl of Coventry and has been restored after 12 months of work. The National Trust has plans to further improve the route with new planting.
Lost over time, the organisation said archaeologists discovered the original path, which has been rebuilt.
Visitors pass tree species including beech, hornbeam, oak, yew, mulberry and an aged phillyrea. Croome's oldest tree, viewable from the park, is thought to be around six centuries old.
Croome warden Hugh Warwick said it had been a "huge task".
"We started work about a year ago, with over 84 trees to be felled as well as reinstating the paths and building benches. We’re really pleased to finally open this area up and share it with our visitors and the stunning views across the haha to South Park. It’s a very significant piece in the Croome jigsaw."The scheme is part of a larger project to restore the parkland, much of which was built by Capability Brown in his very first design, the National Trust added.
