Popular Routes
North of Eynsham (which is west of Oxford) the nearest main road is the A40 and it looks to be agricultural land.
If you look straight up from Eynsham, there's a road called Lower rd and to the left there's a road called Cuckoo Lane , the crossed hammers section is between these 2 roads.
Sorry , I've just read the replies , apparently they're open mine works (i suspect, given the local geography, these are gravel woks.
Thanks anyway
