Tips from the Community

Andy Lewis MTB 🇬🇧
July 12, 2025, Cardiff Bay Barrage Locks

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.

This imposing building stands out from the relatively flat surroundings and harks to a by-gone era. Impressive stature!

Great cafe on the A48, with plenty of space to lock up your bike as you head in for coffee, etc.

Good Coffee and Cake, but really loud (too loud) music. But always a welcome stop.

The St Lythans burial chamber (Welsh: Siambr Gladdu Llwyneliddon) is a single stone megalithic dolmen, built around 4,000 BC as part of a chambered long barrow, during the mid Neolithic period, in what is now known as the Vale of Glamorgan. It lies about half a mile (1 km) to the west of the hamlet of St Lythans, near Dyffryn Gardens. The site is on pasture land, but pedestrian access is allowed and is free. https://en.wikipedia.org/wiki/St_Lythans_burial_chamber
