The Shimna River winds through Tollymore’s woodland, past bridges and riverside scenery. Choose a short arboretum walk, a river trail or a longer forest and hillside outing.
Planting in the arboretum began in 1752 as part of a Georgian landscape. Its tree collection gives you plenty to look at even on a shorter visit.
