Cardiff is very flat and easily negotiated by bike. You’ll find plenty of bike racks around the city centre and cycle paths like the Taff Trail provide traffic-free routes.
To get here by bike, we’d recommend using Google Maps’ excellent Bike route planner. An example journey – from Bristol to Cardiff – can be seen at this link. The Taff Trail also provides a great bike ride to Cardiff from Brecon. Learn more about the Taff Trail and cycling routes here.
