Red Lake lies in the heart of the Southern Moor. There is a distinctive landmark - the overgrown spoil tip of the China Clay works that started working in 1910 but had failed by 1933. Clay was hosed out from a deep pit and the slurry was transported via pumps to settling beds at Greenhill about a mile away. After a week or so of settling the sluices were opened and the clay in suspension flowed down pipes some 7 miles to the clay processing works near Ivybridge. The unwanted sand and gravel was loaded into trucks at Red Lake which were then tipped onto the waste tip that we see today. There was a railway which ran alongside the clay pipes that led down to Ivybridge. This was only used for moving people and basic materials and is popularly known as the Puffing Billy track - although on the map it is named as The Two Moors way). The railway was of 3ft gauge and small steam engines pulled 3 passenger carriages. Only the trackway remains - the rails are long gone. Today, Red Lake is an isolated place. There are 3 deep pools, ruined buildings as well as the tip. It is surrounded by mires and fen but is an interesting place to see. When you visit there you'll see why it's called Red. Lake derives from the old Dartmoor meaning of stream rather than a body of water.we did this walk yesterday, it was too far really ,i am still suffering today with my legs, it was thirteen miles when we got back to the car,
