The Fleam Dyke and Roman Road Walk is a 40km (25 mile) waymarked route, incorporating two of Cambridgeshire’s ancient linear sites. It passes through gently undulating countryside comprising chalk grassland, woodland, farmland and it skirts a number of attractive villages, a country park and a nature reserve. There are extensive views from some of the higher points. Both Fleam Dyke and the Roman Road are archaeological sites of national importance, and large sections of each are scheduled monuments. Also, some parts are Sites of Special Scientific Interest (SSSI), well known for their chalk grassland flora and fauna. In summer there is a profusion of butterflies, more than 20 species having been recorded on each site. The Icknield Way Path links Fleam Dyke and the Roman Road through the village of Balsham and this section of the path can be used to divide the walk into two approximately equal parts.
