The path runs from St Albans, close to St Albans Abbey railway station and the site of Roman Verulamium, through Fleetville and Smallford to Hatfield; it ends close to Hatfield railway station.

The remains of most of the station platforms still exist along the route, with many as of 2017 having recently been refurbished along with signage and street names painted into the tarmac.

A station building still stands at the London Road exit in St Albans, which has been converted into a nursery, while at Nast Hyde Halt a replica semaphore signal has been erected along with a garden and other signage.

At what used to be Hill End Station, a small remembrance park has been created to remember a former mental health hospital that existed at the site.

There was once some speculation that the railway may be reinstated in the future as an extension to the proposed Abbey Line tram system[2] although this never materialised.
