Dinefwr Park wildlife walk, Carmarthenshire


This 3-mile walk takes in some of the estate’s great wildlife-spotting places, as well as a fascinating medieval castle and 17th-century mansion.

Explore the only National Nature Reserve in Wales

Dinefwr’s historic parkland is famed for its abundance of wildlife and stunning valley views. Some of the 'veteran' trees are thought to be more than 700 years old and support such a high diversity of lichens and invertebrates that the park has been declared a Site of Special Scientific Interest. In July 2007 it also became a National Nature Reserve – the only parkland NNR in Wales.

Turn right out of the Welcome Centre and follow the dragonfly waymarks (Dragonfly Walk) until you get to the pump house. Then, follow the heron waymarks (River Walk). Head downhill, past the pigeon house on your right (pigeons used to be a source of meat for the household). Mynachdy, an old gameskeeper's cottage, is soon passed on your left.

Turn left here on a path to Llandyfeisant Church.


An important feature in the designed landscape, this church was largely rebuilt in the 19th century but actually has medieval origins.


On the track back to the Welcome Centre, pass what would have been a large Roman fort over the hill to your right. Archaeological surveys show us it existed, but nothing is visible above ground. All that remains is for you to admire the long-horned white park cattle as you cross the parkland and return to your start point.
