The Porchfields and Trim Castle River Walk
About 4 km return · Flat elevation
About
The river walk from the castle out to Newtown is the thing Trim people actually do, most days, in most weather. It leaves the castle grounds, crosses the Boyne, picks up the Yellow Steeple and the Sheep Gate, and then runs out along the north bank through the Porchfields, a medieval open field system that survived because it flooded and so was never built on. It ends among the Newtown ruins about a mile and a bit downriver. Meath County Council has put interpretive panels with QR codes along it, along with benches, a wildflower meadow and an outdoor gym, so it is a genuine town amenity rather than a heritage trail nobody uses. Allow roughly half an hour each way at a walking pace, more if you stop at the panels.

Tips
- →The Porchfields are water meadow and flood. After heavy rain sections go soft, so boots rather than trainers in winter.
- →Marcie Regan's at the Newtown end is the traditional finish, but it keeps its own hours, so do not build the day around it.
- →There is no lighting along the river section, which matters in winter when it goes dark by half four.
