Where can you park for the Slievenaslat viewpoint walk at Castlewellan?
Use the Lakeside car park at Castlewellan Forest Park and follow the yellow-marked Slievenaslat walking route.
The approximately 2.2-mile loop climbs to the Slievenaslat summit area, with rocky sections and many steps. The published trail is graded very strenuous despite being shorter than some of the park's easier walks.
Practical advice: Do not judge this route by the flat lakeshore paths visible at the car park. Wear suitable footwear, allow for the steep climb and check conditions at the information board; it is not the same as the family-friendly green trail.
