Castell Coch

Nantgarw to Castell Coch

From the A468 at Nantgarw go through the cycle gate by the heavy wooden way marker. Cycle down the hill past the junction with National Cycle Network Route No 4 and continue down the gradual slope.

After about 500m there is a signpost and junction. Turn left onto a narrow lane and turn right up the hill under a bridge and through a cycle gate to a picnic area with a panoramic view over the River Taff and Valley.

We are now on another former railway track. Follow this for approximately 1.5km. A sign to the left shows an easy route downhill to Taffs Well Station. Continue to another cycle gate, beyond which is an unsurfaced track - turn left. This forest trail provides a continuous climb to the hill above Castell Coch.

At the top the track levels out. Watch carefully for the path on the right which drops down to Castell Coch. Take this path very slowly and be prepared to dismount. It is very steep and narrow and at holiday times and summer weekends this path is quite busy with pedestrians.

Castell Coch

Castell Coch, the fairy tale castle overlooking the valley and with a view of Cardiff right down to the docks, is on the high level route of the Taff Trail from Tongwynlais to Nantgarw. This Victorian castle elaborately furnished and decorated by William Burgess for the Marquis of Bute is well worth a visit.

or see the full tour audio and video at

The route includes the steep main driveway to the castle and a narrow footpath climbing up through the forest. Both of these are very steep requiring stamina. Care is also needed especially at holiday times and weekends, as the narrow paths get very busy with pedestrians including small children.
