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.

Great photo opportunity, but the area can be busy depending on the weather and it’s likely any progress on a bike would be very slow. Early mornings and evenings are good.

Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

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.
