| The River Mimram close to the village of Welwyn |
This walk starts in a small car park at the eastern end of the
Ayot Greenway then crosses some lovely rolling countryside before dropping down to
Welwyn, often called Old Welwyn, a village in the valley of the
River Mimram, where you will find several pubs, restaurants, cafes and shops selling refreshments. At a few sections of this walk you will be aware of the sound of the A1(M) and there is some urban walking as you enter and leave Welwyn. A couple of sections of the route can be muddy after rain.
