The reserve is situated to the east of Potters Bar, just north of the M25 motorway off Coopers Lane Road. It is one of the best remnants of the ancient Enfield Chase. Diverse woodland, meadow and wetland habitats support an abundance of species. The reserve is divided into two main areas of woodland (Fir Wood to the north and Pond Wood to the south) which are predominantly oak and hornbeam. Within Pond Wood there is an ancient meadow which is being conserved with the help of grazing Shetland sheep. At the southern end is a lake which is being actively maintained by the Trust.
