Refine your search for walks in Old Mellifont Cistercian Abbey Monastic Site
Boyne Valley Camino
This is a track of my walk along the route of the Boyne Valley Camino. The official map & details are available from their site and the walk has very visible markers.
I had a Camino passport (from Camino Society Ireland) and wanted official stamps. In Tullyallen, the official stamp is now available from Aggie's Coffee Hut, which is open most days. This is a good spot for a short rest, as there is a covered seating area.
I took two short breaks on the walk and spent a total of 6h12. If this is your first time visiting Mellifont Abbey, you should take more time than I did to have a look around when you get there.
On the homeward bound leg, I detoured into the Tourist Information Office in Oldbridge Estate for another official stamp. However, if you don't wish to collect stamps, you can instead continue on the waymarked route and save yourself approximately 1.4km! However, there is a coffee shop inside the walled garden nearby, where a weary walker might wish to take a break.
