A large portion of South Wales is small towns and villages built on hills and mountains, so it's difficult to cycle from place to place for most people.

The Taff trail forms a convenient path from Pontypridd to Cardiff that doesn't require travelling over steep hills. Further into the South Wales valleys past Ponty, each valley has their own cycle trail that links to the Taff Trail. Commuting around the valleys and to Cardiff is only tough going if you follow the motorways instead of pre-existing cycling infrastructure.

The main problem is travelling between valleys since you're either going over hills or circling 'round to Ponty but this is also a problem with public transit infrastructure which uses Ponty as hub so if you're going say Merthyr to Maerdy you have to catch a bus or train to Ponty and then a bus to Maerdy.
