Once a designated gravel pit, today a haven bustling with wildlife all year round.
During the Coronavirus epidemic, most of our sites remain open to the public.
Our hides have reopened – in line with Government guidance on enclosed spaces, all visitors are asked to wear a face mask unless exempt – our teams will be doing the same.
We ask that all visitors follow Government guidance to avoid contact with those you do not live with when visiting our sites. Remember to allow sufficient space for your fellow visitors where possible. You can find out more about our response to Coronavirus and how you can keep yourselves and others safe on our update page here.
Please take extra care not to disturb wildlife. Follow on-site signage and keep dogs under effective control. Never light a fire or BBQ, do not go swimming or boating, and take all your rubbish home with you.
Please follow Natural England's Countryside Code and Respect, Protect and Enjoy.
