Hertfordshire is a mixed county ranging from the Chiltern hills and valleys in the west to the Lea Valley in the east.    Rare orchids can be found in the beech woods on the chalk hills of the Chilterns and the Lea Valley is a fantastic  wetland corridor bringing birds on to the doorstep of London.  We can only highlight a few special places here, but for more information go to the Hertfordshire Natural History Society and the Herts & Middlesex Wildlife Trust
