Two local walks from the Harwell News, 1981, with photos from 2020.
Circular Walk no. 1
W.B.W will be Bill Woollen
By 1902 Parish Award Map he probably means 1812 Parish Award Map (as mention in the next walk)
Approx. 2.9 miles.
Circular Walk no. 2
Approx. 1.6 miles
A third circular walk is now (Feb 2021) possible going down Cow Lane and back round the western edge of GWP.
This could be combined with walk #2 above.
