Forest bathing at Parc Cefn Onn

Parc Cefn Onn is a wooded valley garden of about 12 hectares on the northern edge of Cardiff, owned by Cardiff Council. It is a Grade II listed historic park, laid out around a century ago by Ernest Prosser, a director of the Rhymney Valley Railway, with a woodland garden added after 1944. The Nant Fawr stream runs down the valley through ponds, under native and exotic trees that include dawn redwoods and a grand fir around 48 metres tall.

From the car park, two waymarked routes make a loop of about an hour, longer at an easy pace. Many paths are built for easier access. Spring brings bulbs, camellias, rhododendrons and azaleas, and autumn brings colour from the tree collection. For more native woodland, the paths continue into Coed Transh yr Hebog, semi-natural oak and beech, and on to the Caerphilly Ridgeway. Lisvane and Thornhill station is the nearest stop.
