Meldon Valley, Devon

There are various attractions here for walkers and others to explore. There is a reservoir, a listed railway viaduct built of metal, an old quarry pool, and various bits of industrial archaeology. A cycle track across the viaduct gives access to places further afield. The working quarry at Meldon uses a branch railway line, which is also used on Sundays for Okehampton-Meldon leisure steam train services.
I parked near the reservoir and had a walk around, passing under the viaduct, and I photographed some holes that looked like old workings. None of the hole pictures came out very well. In the virtual tour (below), an old engine driver reminisces that winds on the viaduct used to be felt on the trains, so cyclists should take warning.
There is a virtual tour of the valley at Virtual Tours.
