Portreath Harbour Entrance

Highlight • Beach

Portreath has an inner and outer harbour. The harbour was historically an important port and was one of the earliest industrial ports in Cornwall. Cornwall's first railway, the Portreath Tramroad, linked the harbour to the mines in Scorrier and St Day.

Close to the harbour entrance is a white circular hut which is located on a raised section of cliff. This hut is known as 'Dead Man's Hut' and was initially the Harbour Master's lookout. The name originates from when the hut was used as a temporary morgue for bodies washed ashore.

Bike Chain Bissoe Café

Highlight • Cafe

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!

Point Hills Arsenic Refinery Chimney

Devoran Quay

Highlight • River

Devoran is the end, or start of the Cornish off road coast to coast trail which journeys from (or to!) Portreath. There is a pub, The Old Quay Inn, for refreshments and a car park, next to the A39, which is a handy place to park if you are starting a ride here.

In the 19th century Devoran was an important transport hub for the mining industry. Tin and copper were brought here by railway from the Gwennap mines. When the price of tin fell dramatically, mining was no longer the huge industry it was before and the creek silted up through its lack of use.
