It has been a while since I last did this hike but as access isn’t the best, the start is very steep and the ridge pretty narrow I figured it would be ideal for avoiding crowds.
The hike starts at Little Black Hill car park with a short but steep ascent to the top. The ridge at the top is narrow and rocky with a bit of scrambling required from time to time. As you continue it widens and heads steadily uphill till you reach Black Hill. From there you just continue along the ridge to Hay Bluff. It is about 4 miles each way with amazing views in all directions.
