Route Breakdown

1. Car park → Newton House driveway

Begin from the car park and follow the driveway past the front gates of Newton House. Go through the metal gate across the drive. To your right lies the outer park, where the rare White Park cattle graze for much of the year. On your left is the historic deer park, laid out in the 1770s and admired by the Picturesque Movement. Some of Wales’ oldest trees stand here, supporting a rich mix of wildlife.

2. Newton House driveway → Deer park entrance

Continue up the drive, pass through the wooden fence line, then turn left. Ignore the sign to the ice house and instead head straight through the gate into the deer park. Follow the brown‑waymarked path through the woods. Breaks in the trees offer sweeping views across the parkland. Ravens and red kites nest here each year, just as they did when Capability Brown suggested this very walk in 1775.

3. Deer park → Millpond

Follow the woodland path downhill until you reach the millpond. Keep an eye out for the fallow deer herd — in summer their coats are spotted, and males grow broad, shovel‑shaped antlers for the autumn rut. A second herd roams outside the deer park and is often seen in autumn and winter.

4. Millpond → Bridge & pump house

Leave through the metal gate and cross the bridge between the millpond and the old pump house. The waterwheel here once pumped drinking water from a spring on the floodplain up to Newton House. On still days, the millpond reflects the hillside of Cae Lan beautifully.

5. Millpond → Castle Field

Follow the track around the millpond and out into Castle Field. This meadow is managed as a flower‑rich hay meadow, with yellow rattle indicating high biodiversity.

6. Castle Field → Dinefwr Castle (optional)

Capability Brown’s original walk followed the ridge above the field, passing the castle. You can take a detour up to Dinefwr Castle for spectacular views over the Tywi Valley — well worth the climb on a clear day.

7. Castle Field → Car park

Otherwise, continue along the track to the left, pass through two gates, and follow the rising path back to the car park.
