.the blue route- 9 or 14 miles iirc, very flat and boring but through lots of chase countryside
.the play park at birches valley or at the visitor centre
.woodland walk round the ponds. (
.The remains of the gruffalo trail, I think the big wooden guy is still there.
If they want to have a picnic, my advice is to have it at the tackeroo campsite, nice wooden benches and virtually deserted apart from people on bikes rolling past but in comparison to birches valley A LOT more quieter. After lunch they can then run around the area, or cycle, bug hunt, make dens all that sort of stuff. It isn’t a campsite in the traditional way.
