Hay Castle

Highlight • Historical Site

Hay Castle is a medieval fortress and a 17th-century Jacobean mansion house. The fort was built in the late 12th century and is considered to be one of the greatest medieval defence structures on the border of England and Wales still standing. However, this comes in spite of its past. The castle was attacked and burnt several times during the first and second Barons' Wars, the wars with the Welsh princes, the rebellion of Owain Glyndŵr, as well as the Wars of the Roses.

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.

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.

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.

Brecon Castle

Highlight • Castle

Brecon Castle is a very unique place. It is a castle that is now within the grounds of a private hotel. Though most of the original castle is long gone, there are still the imposing remains of the tower left, and this is visible from many areas of the town. There is a particularly good view of it from the town bridge. Strategically sighted, overlooking the confluence of the Afon Honddu and the River Usk, it dominates this part of the town and is a reminder of the powers of the Normans when they started to build it in 1093. Originally, the castle would have had two entrances as well as a postern gate. There would have been a drawbridge over the River Usk and another over the Afon Honddu. At the time, it was built as the administrative and military headquarters of the Lordship of Brecon and as a reminder to all that they lived among one of the most powerful families of the day.

St Bilo's Church, Llanfilo

Highlight • Religious Site

A very pretty village on a hill. The medieval St Bilo's Church has a 15th-Century rood screen and loft, a ribbed barrel roof and the lychgate is one of the oldest in the country!

Hay-on-Wye Clock Tower

Highlight • Historical Site

The pretty clocktower in Hay-on-Wye was built in 1881, costing £600, which seems good value these days. If you think you've seen it before, it is the same design as the clock tower in Knighton, a border town about 20 miles north of Hay.

Is the Brecon to Hay-on-Wye loop dog-friendly?

While much of the route is on quiet country roads, which can be suitable for dogs on a lead, some sections may involve busier roads or areas with livestock. Always keep dogs under close control, especially near farm animals, and be mindful of other cyclists and road users. Consider the distance and difficulty for your dog's fitness level.

Do I need any permits or pay an entrance fee to cycle in Bannau Brycheiniog (Brecon Beacons) National Park?

The park is open access for activities like cycling on designated routes and public rights of way. However, always follow the Countryside Code, respect private land, and leave no trace.

How long does it typically take to complete the Brecon to Hay-on-Wye loop?

For a touring cyclist, the route is estimated to take around 4 hours and 15 minutes of active cycling time.

Due to its significant elevation gain, distance, and classification as 'difficult', this specific loop is not recommended for beginners or young families. It requires very good fitness and experience with challenging climbs. There are other, easier cycling options available within the wider Brecon Beacons area for those seeking a more moderate experience.
