Castell Coch

Tongwynlais to Castell Coch

Going North from Tongwynlais, the Trail divides the route via Castell Coch is sign posted as the High Level route which was theoriginal and more strenuous route.

From the Lewis Arms go up the steady gradient of Mill Road past the Castlecoch Golf Club to the gateway of Castell Coch. The steep driveway to the castle is short but strenuous.

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.

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.
