The Cole Green Way is a rail trail which runs east-west from the eastern edge of Welwyn Garden City to Hertford in Hertfordshire.

Part of National Cycle Network Route 61, and the Lea Valley Walk, it runs for more than six miles along the former Hertford, Luton & Dunstable branch line from Welwyn Garden City railway station to Hertford North railway station.

At the far end of the car park and associated picnic area, almost hidden in the undergrowth are the remains of buffers, presumably from station sidings.

The woodland associated with the car park and picnic area has a number of items carved from standing wood.

A further bridge was filled in further along, which means users must cross a country lane before rejoining the trail.
