The path starts by Hertford Football Club and there are entrance and exit points at a number of points along the way. There is also a picnic spot at the site of the former Cole Green Station. The building that was once Hertingfordbury Station survives and is now a private residence.
The path emerges in Welwyn Garden City just off the B195, Black Fan Road, to the east of the town, having passed under the A414.
The railway line opened in 1858 and served Hertingfordbury and Cole Green on it's way to the junction at Welwyn. The line closed in 1966 along with thousands of others following the implementation of The Beeching Report.
A useful leaflet is published by East Herts District Council on The Cole Green Way and the towpath to Ware, both of which form part of National Cycle Route 61. The leaflet is available here (PDF) on the EHDC website.
