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.

Excellent track around the reservoir suitable for most bikes with gravel tyres. The Usk Reservoir, also known as Cronfa Wysg in Welsh, sits at an elevation of 1,006 feet (307 m) in the upper Usk Valley within the Brecon Beacons National ParK. It marks the county boundary between Carmarthenshire and Powys.
