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.

Cathedral Close winds its way through the grounds of Llandaff Cathedral, where you can take in the in the striking 12th century architecture. You can easily stop and explore the grounds, and be sure to visit the Old Bishop’s Palace, a medieval fortress located at the junction of Cathedral Close and High Street.

Glyncorrwg Mountain Bike Cafe is worth a stop for good food or a cuppa if you ride up the Afan Valley.

The weir spans the River Taff, which flows directly through the heart of South Wales. It's a nice place to stop and refuel with picnic benches and a peaceful atmosphere.
