Use the western Succoth car park off the A83, just west of Arrochar; it gives the easiest woodland access. Cross the road to the fox carving to start. Forestry and Land Scotland parking passes are not valid at Succoth, so follow the lot’s own terms. There are no shops or cafés on the hill; the nearest toilets, shops and cafés are in Arrochar village. Buses from Glasgow stop in the village, and Arrochar & Tarbet station is about a mile and a half from the car park by forest path.
This is a long, steep ascent over uneven ground, not a groomed summit path. The North Peak’s overhang and the central pinnacle have serious drops, so keep to the northern summit route and well back from exposed edges. Streams are crossed on stepping stones, and the upper rocky section asks for steady footing. If you want a shorter outing, Narnain Boulders are a natural turnaround before the steep steps, though that leaves out both peaks.
