Mardley Heath

Location Scout & Guide HQ, Canonsfield Road, Welwyn, AL6 0QA. OS Grid Ref TL242179
Terrain Mardley Heath is a small but complex woodland, mainly regenerating naturally following gravel extraction in the middle of the last century. A small area of open heathland has been maintained in the northern part of the site The area is now a Local Nature Reserve owned and managed by Welwyn Hatfield Borough Council, who have kindly given us permission for our event.

Gravel working has left this area with complex contour detail, in addition to the already hilly nature of the site. Public access for walkers, horse riders and cyclists has added a maze of small footpaths. Open areas and the mature remnant former woodland offer fast running, whilst the less mature areas provide plenty of route choice where close contact with the map will be required.

Parking Free parking will be on the road near the Event Centre and around the A1(M) bridge. Space is very limited and it would be greatly appreciated if people can share transport. The local lanes are not suitable for parking, so please do not park there, this is to try to minimise congestion.
