10.3 km

Poldice Valley is a beautiful spot with a rich mining history. A mine has existed in the valley as far back as the 16th century, extracting tin ore and copper from the area. The Portreath Tramroad was opened in 1812 to transport the materials to Portreath harbour. The mines slowly declined towards the end of the 19th century and ceased operating in 1930. Today, you can still see many ruined mine buildings and mineshafts in the valley.

Carn Brea Castle

Highlight • Historical Site

There's a great network of gravel trails across Carn Brea, which are a mixture of bridleways and footpaths, so best to check before you ride.

At the top, the Carn Brea Castle dates back to the 14th century when it was built as a chapel before being converted into a hunting lodge in the 18th century.

Now the castle is run as a Middle Eastern cuisine restaurant. Quite the setting!

South Wheal Francis mine ruins

Highlight • Monument

This is an incredible piece of Cornish industrial history. Once a copper and tin mine, the ruined buildings offer a fascinating glimpse into Cornwall's past. Now overtaken by ivy and moss, it is hard to imagine the dangerous and dirty work that would have been happening here.

The mines here dug into the Great Flat Lode, now a waymarked cycling trail, named after the mineral rich body of rock south of Carn Brea.

Wheal Basset Stamp's Engine House Ruins

Highlight • Monument

Wheal Basset produced over 128,000 tons of copper ore between 1832-1880 and was a particularly important mine of the Great Flat Lode.

The well preserved Wheal Basset vanner house was built in 1908, where the mining ore was processed.
