Always a nice ride across this section. Great views, but can be mucky in the winter.

Each lock is crossed by a Bascule bridge, to carry pedestrians and vehicles across. These are lifted for boats to pass. The weight of the bridge deck is counterbalanced by an overhead weight on the opposite side of the pivot. Five sluice gates control the level of water in the Bay. Each sluice gate is 9 metres wide and 7.5 metres high. The sluices open to maintain the level of the Bay, and close when the estuary level is higher than the Bay to prevent seawater entering the freshwater lake.

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.

I just wish there were even more bridges over the River Taff. Each crossing over has its unique and wonderful views. This one is no exception!

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order
