Grosmont Castle is maintained by Cadw, and at the moment there is a lot of work going on with the refurbishment of the timber footbridge spanning the castle ditch, i.e., the entrance. Therefore, the castle is closed between February 2026 and September 2026. It is still worth a visit as you can still walk around it and get some impression of mediaeval life from viewing this grand structure.

White Castle is a ruined but super nice castle to visit and sits between the villages of Llantilio Crossenny and Llanvetherine. It is part of the 'Three Castles' group, along with nearby Grosmont and Skenfrith. These historic Norman fortresses were built to control the border region, and White Castle is known as the most imposing due to a strong inner and outer ward. It also has an imposing, water-filled, stone-lined moat. It is free to enter and maintained by Cadw.

Although there is not much left of the castle, this is an atmospheric place that is well worth the detour from the trail. It also looks like many of the stones from the castle were borrowed to build the nearby farm!

Snodhill Castle is a romantic and picturesque ruin, perched above the tiny settlement of Snodhill in Herefordshire's Golden Valley. Recent investigations suggest it was one of the first castles in Britain to receive masonry defences in around 1100. Most castles at this time would have been constructed from wood. The castle's former might, coupled with its strategic position, would have made it a fortress of some importance. It has undoubtedly played a role in the various wars that have been fought in this border country through the ages.

Below the gentle slopes of the surrounding hills, Kentchurch is a lovely village by the River Monnow in Herefordshire. According to some, it was the home of the legendary Jack o' Kent, a popular bogeyman figure in Herefordshire and Monmouthshire folklore. The Bridge Inn does excellent food. The historic Kentchurch Court is a Grade I-listed building that dates back to the 14th century. It has seen many revamps, not least in the late 18th century when it was given a gothic remodelling by John Nash.

Nestled in classic border country, Kilpeck is a pleasant Herefordshire village. Part of the Welsh Kingdom of Ergyng until the 9th century, it became part of Archenfield after the Norman conquest. In the 16th century it became part of England, though Welsh was still commonly spoken here until the 19th century. It is notable for two landmarks in particular: the remains of a motte-and-bailey caste and its small but remarkable Romanesque church of St Mary and St David's.
