Rhayader is the oldest town in Mid Wales. It sits where the River Wye flows from the high Cambrian Mountains. Its name means waterfall on the Wye in Welsh. A lost cascade once roared here before a bridge was built in 1780. The streets hold memories of the Rebecca Riots and farming life. Nearby, Gilfach Nature Reserve protects an old longhouse in the Marteg Valley. You can walk the ancient Monks Trod or watch salmon jump in the falls. The busy livestock market still defines this inland hub. Skilled makers at the Welsh Royal Crystal workshop keep local crafts alive. This place offers a deep look at true Welsh heritage.
