The fields are not suitable for buggies/pushchairs or wheelchairs but would be good for walking your dogs and when these were placed we had four children aged 10, 7, 7 and 4 with us and they coped with the walk fine.
This can be done as a cache and dash but to enhance the experience and for your own piece of mind you should do the whole trail. If you are parking here please be careful as you are near a bend and cars do drive faster than they should. You're looking for a small tupperware container.
