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

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.

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.

The Taff Trail runs for 55 miles between Cardiff and Brecon along a mixture of riverside paths, railway paths and forest roads. Due to the range of path surface types, a sturdier cycle is recommended for some sections of this route. These include a short section from Quakers Yard to Pontygwaith and from Pentwyn Reservoir to Talybont Reservoir.
