A short, easy cycle route, the seven mile Cardiff to Castell Coch trail can be completed in just a couple of hours. Starting from the Victorian-designed Bute Park, you will cycle past the Millennium Stadium and Melingriffith Water Pump before arriving at the turreted, fairy-tale like Castell Coch. This cycle route is a short stretch of the 55 mile Taff Trail which runs between Cardiff and Brecon – perhaps one for a day when you don’t have the kids in tow.
