‘Capability’ Brown walk, Carmarthenshire


There are nearly 300 ancient trees at Dinefwr, half of them in the deer park. The path you'll follow on this walk was designed by Lancelot 'Capability' Brown when he visited Dinefwr in 1775.

Discover ancient oaks and wildlife in the deer park

As well as seeing views of the park and house framed by specimen trees, you might catch sight of some of the fallow deer that live here. Autumn is the rutting season, when the males (bucks) have very impressive antlers that they use to fight for the females.

From the Welcome Centre follow the driveway up past the front gates of Newton House. Go through the metal gate across the drive. To the right, back towards the town of Llandeilo, you'll see the outer park where the White Park cattle graze for much of the year. The clumps of trees and tree-lined avenues were laid out in about 1770 by George and Cecil Rice. On your left is the deer park, which was much admired by followers of the Picturesque Movement, which was fashionable in the 1790s.

Carry on up the drive and through the wooden gate, then turn left. Instead of following the sign to the ice house, head straight on and go through the gate into the deer park. Follow the brown path through the woods, stopping at the breaks in the trees below you to admire the different views of the park. Lancelot 'Capability' Brown suggested this walk, and the specimen trees to be planted along it as markers, when he visited Dinefwr in 1775.

Follow the path through the woods down to the mill pond. Look out for the herd of fallow deer that roam the park. In summer their coats are spotted, and the males grow large, shovel-like antlers for the autumn rut. These are shed in spring, and you might find a set on your walk.

Go out of the metal gate and turn across the bridge between the mill pond and the pump house below. The waterwheel in the pump house was used to send drinking water from a spring on the flood plain up to Newton House.

Follow the track around the mill pond and out onto Castle Field. We're managing the field as a flower-rich hay meadow. The abundance of the flowering plant Yellow Rattle in the grass is a good indication of biodiversity.

The walk suggested by 'Capability' Brown went along the ridge above the field, passing the castle. You can take a detour here to go up to the castle and admire the views over the Tywi Valley. Otherwise, follow the track round to the left, through two gates, and back up to the car park.
