Broxbourne Woods is a designated National Nature Reserve located in Hertfordshire, covering over 200 hectares of ancient woodland. The site contains remnants of Bronze Age earthworks and historic boundary banks that trace back centuries. It serves as one of the largest remaining oak-hornbeam forests in the region.

It supports significant populations of protected species, notably the purple emperor butterfly and various nesting woodland birds. Several marked trails navigate through the different compartments of the reserve. The area is managed by Hertfordshire County Council to maintain its biodiversity and historical features.
