Hailey Park to Tongwynlais

(approx 2.4 miles 3.8km)

From Hailey Park we follow Ty Mawr Road. Because the marked cycle paths follow a line at the back of the pedestrian path and follow the curve around and into each of the side roads, cyclists are forced to cross over at a point where visibility is poor. The cycle track should follow the front line (adjacent the road) and the side roads should be marked with a double give way. This layout appears to be favoured in the countries of continental Europe where cycle usage is higher than here.

Turn left into the path immediately after the Melingriffiths Canal Water Pump. The path follows around to Forest Farm Road.

Here there is a cycle gate with insufficient space to merge with the road properly. My bicycle is 6 feet long from wheel rim to wheel rim. The space after the cycle gate is less which means I have to enter the road at right-angles to avoid the adjacent hawthorn bush. This means going most of the way across the road before straightening up on the left hand side. This is a traffic hazard.

Now continue past Cardiff HSOB RFC Diamond Sports Ground, Forest Farm conservation centre, the footbridge across the river to Radyr where there is a station. then past Radyr Weir and Fish Pass, under the M4 past the "Iron Bridge" and under the A470 to Tongwynlais.


Tongwynlais is a small village on the on the edge of the Valleys and on the Cardiff end of the narrow Taff Gorge. It attracts visitors from outside the area because of the unusual Castell Coch which towers on the hillside above. From the cross roads outside the Lewis Arms: to the north-west is Taff's Well; to the north-east is Castell Coch; whilst to the South is the route to Cardiff.

Tongwynlais has provisions, Fish & Chip shop, pubs and a cycle shop.

Although there is a 20 mph speed limit in the Tongwynlais, the "traffic calming measures" are particularly difficult for a cyclist to negotiate safely. Some motorist give way to bicycles others don't. Speed bumps are very high and need to be cycled around or out of your saddle. Also 2 of the road narrowings have vehicles approaching from 3 directions at once.

Going North, the Trail divides here with the older, more strenuous route via Castell Coch. The sign post now shows this as Taff Trail - High Level.

Going South to Cardiff, with minor exceptions the trail stays close to the River Taff.
