The Barrage connects Penarth to the Cardiff peninsula. It offers stunning views across the sea to one side, and the freshwater bay on the other. One of the highlights of the Cardiff Bay tour

Llandaff Cathedral is magnificent building nestled within the small community. There are also other historical buildings close by and it is worth a visit. Not from the city centre and the Taff Trail. Beautiful scenes in the autumn too as the leaves change colour.

The road winds up from the Rhondda valley onto open moorland where the main challenge often becomes the significant exposure to wind. Enjoy the sweeping panoramic views from the top of this popular and rewarding climb.
