Trim Castle River Walk

There is a long path along the River Boyne and a path that circles around the castle as well.  The River Boyne is close to the castle as you can see in the drawing of the river and the walled castle.  There is a swampy area close to the castle as well, and it would appear that at times the river could come all the way up to the castle wall.  It would be a lovely walk along the river and there were people running the path as well.
