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 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.
