The Pits, former clay and sand workings are located at St Erth near Hayle.
The site is a nature reserve owned by Cornwall Wildlife Trust and was Cornwall's first geological reserve.
The pits are now overgrown by semi-mature woodland.
The clay from here was used for several purposes - Bernard Leach, the famous potter often used it; and in 1881 it was used for the lining ('puddling') of a new dock in Penzance.
Harvey's Hayle Foundry obtained its moulding sand for metal casting from this location.
The St Erth beds contain the fossilised corals, sea snails and sponges.
The one hectare reserve is accessed by a circular trail of footpaths and is open all year.
St Erth Pits are dog friendly with dogs allowed all year round.
Parking is available in St Erth village.
