Route Description
Part of the new Castlewellan Walking Trails launched in November 2014, this trail is signposted from the Lakeside car park - follow the yellow waymarkers.
Starting at the Lakeside Car Park, follow the north side of the lake before starting the steep climb to the summit of Slievenaslat (272 metres). Openings within the forest and the summit itself provide panoramic views of the Mourne Mountains and the drumlin landscape of Co.Down before commencing your descent.
The most strenuous walk in the Park, this trail is rocky in places with steep gradients and numerous steps both up and down. Variable and uneven trail surfaces are present including large loose material including rocks and roots.
This walk is situated in a working forest environment and may be subject to diversion and closure from time to time.
Up to date information is available on the Forest Service web site - link below.
