This structure is one of the largest canal aqueducts ever built in South Wales. Its four stone arches carry the Brecknock and Abergavenny Canal (later the Monmouthshire & Brecon Canal) across the Usk to enable boats to reach Brecon, on the north side of the river Brynich aqueduct was one of the last sections of the canal to be completed to take the canal into Brecon in 1801. The structure was designed by Thomas Dadford Junior and built by local contractors. The aqueduct is at right angles to the river, reducing its length to the minimum possible. This means that the canal, running parallel to the river, has to turn sharply on both approaches.

There is a steady climb covering 140m of incline from Maen-du Well to the top of Pen-y-Crug. Grade Moderate. Trails can become slippery due to adverse weather conditions. Please take extra care when walking.

As our delighftul Jenny has outlined, Priory Groves is a mixed woodland walk that borders the Honddu river. It is a lovely forest walk any time of year. There are always some birds to see, particularly dippers and grey wagtails. In the springtime, there is a nice display of wild flowers, and the wooden carvings on the trail are super nice. There are plenty of benches to stop at too. This is a really well-known, popular place with local walkers, and runners. It is a very dog friendly place too. The trail is not really accessible to the infirm however, or if you are chair bound. The surface is 90% dirt, and it gets very muddy after some rain. It also has a very steep section half way along the trail that has steps, and even a rope handrail.

The Monmouthshire and Brecon Canal is a small network of a number of canals in South Wales. For most of its currently (2018) navigable 35-mile (56 km). It runs through the Brecon Beacons National Park, and its present rural character and tranquillity belies its original purpose as an industrial corridor for coal and iron, which were brought to the canal by a network of tramways and/or railroads, many of which were built and owned by the canal company.
