The remarkable answer is "YES".
Take for example the walk we did last week. We parked at the National Trust Brownstone Farm Car park. This is just around the corner from The National Trust Coleton Fishacre Property. The car park was far from busy and parking was easy.
We took a leisurely walk along the road laid by the military in WW II with stunning views along the way such as that in the picture above.
Midway along the walk, the strange and otherwordly "Daymark" comes into view. This strange structure sits in a corn field like an alien visitor.
The prosaic reality is that it is a navigation aid for ships out at sea.
