Brynich Aqueduct

Highlight • Historical Site

Brynich Aqueduct carries the Monmouthshire & Brecon Canal over the River Usk. After the green light was given for the aqueduct to be built in 1799, no time was wasted and it opened the following year. The aqueduct has four arches and is 201 feet (64 m) long and 31 feet (9.5 m) wide.

Brynich Lock

Highlight • Historical Site

Brynich Lock and its scenic gatekeeper cottage is situated adjacent to the river bridge over the River Usk near Llanfrynach. It is a super lovely place in a lovely tranquil setting. It was built in 1800 because the section of canal that crosses the River Usk here on the nearby aqueduct is lower than the last stretch of water going into Brecon. It is just a nice place to sit for a while to watch the lock being put to use with the coming and going of the barges.

Monmouthshire and Brecon Canal

Highlight • Structure

This is the canal tunnel that goes underneath the A40 dual carriageway. It is quite a length and the footway is narrow, so if you are on a bicycle I would suggest you take it carefully as pedestrians have right of way here.

Horse-Drawn Tram Cart Wooden Sculpture

Highlight • Structure

Located alongside the Monmouthshire and Brecon canal, this wooden sculpture recalls the horse-drawn tram carts of the early nineteenth century, before railways. At that time, canals and tramways were used to carry freight, including items such as farm produce, timber, and beer in barrels. Coal was also carried for industrial use, domestic heating, and cooking. The main item to be carried was the local limestone so it could be burned in limekilns to produce lime for whitewash, fertiliser, and building mortar.

Brecon Canal Basin

Highlight • River

This is a beautiful canal basin forming the start of the Monmouth and Brecon Canal. It's a beautiful setting overlooked by Brecon Theatre, where there is a cafe/bistro. Meanwhile, on the water, there are chartered barge trips along with boat and kayak trips most of the year. Brecon town centre is nearby, and there is pay-and-display parking on site.

St Mary's Church, Brecon

Highlight • Cafe

St. Mary's Church is situated in the quaint market town of Brecon within the curtilage of its town centre. It has the finest tower in all of Powys, and inside there is even a cafe; funny enough, it is called the Tower Cafe, and a very nice place it is too. The church is one of the focal points of the town.

Watton Bridge (Bridge 165)

Highlight • Bridge

This is the bridge that brings you out by Morrisons garage in the Watton in Brecon.

Monmouthshire and Brecon Canal

Highlight • Cycleway

Our beautiful local canal, which sits on the northern fringes of the Brecon Beacons, is a hidden gem of a place. It is one of the most underestimated locations in Wales and a great plan 'B' walk if the weather is a tad 'Welsh' higher up. Be it walking, biking, or kayaking, this is simply a gorgeous venue! Given life by the River Usk, the Monmouthshire and Brecon Canal stretches 35+ beautiful, tranquil miles between the Brecon Basin and Pontymoile Basin. The scenery here never fails to impress, and it is simply my favourite place on earth!
