A new £500,000 public trail has opened in St Austell.
The trail will give a sense of the workings of the China Clay industry
The Green Corridor Trail stretches for two miles - mainly along the dismantled Trenance Valley Mineral Railway line.
The route is open to walkers, cyclists and horse riders and connects to the recently built 14-mile network of Clay Trails that link to the Eden Project.
The trail has been built by Cornwall County Council with most of the funding from the South West Regional Development Agency.
Officials behind the scheme say it will offer opportunities to watch wildlife and give a sense of the workings of the China Clay industry.
The trail also links St Austell with the Wheal Martyn China Clay Country Park.
