Pen-y-Cae sits in the upper reaches of the Swansea Valley. It is a gateway to the wild peaks of the Bannau Brycheiniog National Park. My top tip is to explore the grounds of Craig-y-Nos Country Park. You can walk the paths by the tall trees and the River Tawe for free. It is a prime choice for a low cost day in nature. The village has deep roots in the mountain life. You can see the old stone houses against the green hills. The air is fresh and the views are clear. Many trails near the caves are dogs welcome spots. It is a smart spot for a trip to the peaks. Life here is calm and tied to the land.
