I've lived in Bletchley( part of MK ) for nearly 60 years and didn't realise we had so much lovely countryside within our boundaries to be able to walk through, yes within our boundaries and not on the outskirts as we knew its a city that was built in the countryside and was surrounded by countryside, the ouse vally Park actually runs through some lovely parts _ villages from 1 end of mk to the other. You can also take various walks off of many of the footpaths and right into the fields with the sheep and cows. The only reason for 4 is more signage would help to know where you are heading, and some areas were still flooded after the heavy rains from a few weeks previous, so we could not walk everywhere we wanted, yes I no you can't factor for the weather but its just a warning if you want to walk this , you may not be able to after heavy rain. Overall, though, great walks, plenty of seating, some local historical plaques informing of what was and is still there.
