What Makes the Dinefwr Castle Walk Special?
Dinefwr Castle, perched atop a hill, is steeped in history dating back to the 12th century. Once a stronghold of Welsh princes, its ruins now offer panoramic views over the Tywi Valley. But the walk isn’t just about the castle. This site is part of the Dinefwr Park and is renowned for its medieval deer park, ancient woodlands, and diverse wildlife.
Dinefwr Park is over 800 acres of parkland, meadows, and woodland. It is a Site of Special Scientific Interest and a National Nature Reserve.


For 3 miles, the circular walk takes you past the National Trust’s Newton House through castle woods. You’ll also cross open parkland filled with grazing deer and sheep. It’s a chance to immerse yourself in centuries-old landscapes and enjoy the tranquillity of one of Wales’ most picturesque spots.
