Baal Pit and Carn Grey is a 3.4 mile loop trail located near the city of Treverbyn that offers scenic views. The trail is good for all skill levels and primarily used for walking. Dogs are also able to use this trail.
A route that follows martian landscapes and ancient tors. This is an excellent walk with only a few hills but fabulous views into an industrial lanscape that is gradually being terraformed. China Clay is decomposed granite, which is found in very few places around the world. The deposits in Cornwall and Devon are the largest. The clay is used in papermaking, paints, porcelains, dyes and cosmetics. China clay was discovered in Cornwall by Cookworthy in 1746. By 1850, there were seven thousand employees in the St Austell district, extracting, transporting and exporting the clay. Production methods have changed considerably due to advances in modern technology, but the industry was one of Cornwall's largest employers for many years. What you will see along this walk are the pits where the china clay was dug out from and the deposits of waste material, from the white paths that you are standing on to the strange green pyramids, all are waste products of the clay industry. If you visit Eden you may be surprised to realize that it once looked pretty much like Ball Pit.
