Castlewellan brings together woodland, lake views and a designed estate landscape north of the Mournes. Choose one of the park’s walking trails, then leave time to explore Castlewellan town.
The Annesley Garden dates from 1740 and is a focal point of the arboretum. The tree collection and Peace Maze offer more to discover beyond the lakeside.
