It is some 3 miles from the Usk Reservoir, and some 6 miles from the source of the Usk below the Carmarthen Fans (mountains).
There are several walks from Trecastle into the surrounding countryside. How about a walk to the Usk Reservoir or a walk into the Brecon Beacons searching for the source of the River Usk And round the day off by quenching your thirst in the village pub.....
