Nestled in the Poldice Valley by Bissoe village, the Bike Chain is a great little cycling shop with a brilliant cafe too. Get everything you need for a ride around the mining trails or the quiet lanes here under one roof; whether that's spare tools, a large slice of cake or simply a little more air in your tyres!

Poldice Valley Mining Ruins

Highlight • Viewpoint

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.
