what are the landowners like, seems plastered with signs.
Ive never had any problems around Tewin/Datchworth/Harmers Green/Oaklands. Harmers green descent to oaklands, which goes by the railway line mentioned by whippersnapper, thats a footpath but its not that busy and is good fun for e herts.
Also a good descent from harmers green to datchworth (well robbery bottom lane or whatever its called), if you go to the left of the wire fencing there is a fun singletrack that meanders down.
Karin, the church is stapleford, yeah good little trail v secluded on both sides – actually it was you who introduced me to it 🙂
