Start Point (Linear) : Car Park at SN732188

End Point (Linear) : Trapp (SN653190)

Walking Directions (Linear)

This option gives tremendous views of the Black Mountain, but does require navigation skills. The linear walk starts at the car park near Foel Fawr on the A4069 (SN732188). The first stretch of the hike follows the ridge westwards. So from the start, head past the quarries to SN716186. Cross the bridle way and continue along the plateau and on to the trig point at SN683168.

From the trig point, head north westwardly, cross the possibly boggy terrain, over the stream (Nant Gwythwch) and up to the rock outcrop at SN676177. This point gives lovely views across to Carreg Cennan Castle, although it will have been visible since almost the start of the hike.

Continue to the road, before taking the track at SN673180 which heads past the farm and around some fields before getting to the junction at SN676189. Take the left fork towards the castle, before climbing over the stile at SN677190 and heading northwards. This path is uneven and probably wet as a stream likes to borrow it in places. After crossing the footbridge, head up the hill to the castle at SN667192.

Heading down the hill, there is a footpath near the castle tourist shop which offers one route to Trapp. It is a bit boggy in places, so an alternative is to continue along the road until the second junction at SN661195. From here, take the footpath heading westwardly. This heads through fields until you get to a second footpath at SN652198. Take the left option, down into Trapp. I haven't walked that last path as I've continued on to Llandeilo, but the route for that is messy!

In Trapp itself, there is a lovely pub to end the walk.

Walking Directions (Circular)

The circular route is initially the reverse of the linear route. Leaving Trapp to the north, then past Carreg Cennan and along the footpath to the road. Once on the minor ridge (SN675177), the circular route diverges and follows the higher ground. Then head up onto the larger ridge at about SN692174 before heading to the trig point and off the ridge to join the road at SN670161. Turn right and follow the road, over the crossroads and in a generally northern direction. These roads are minor and quiet to Trapp.

Notable Features and Highlights

Carreg Cennan Castle

Although in a ruinous state, there is still much to see. It is very photogenic from almost all angles, and should certainly been seen from distance to fit it into it's surroundings. The first castle on this site was probably built in the late 12th century. More information on the castle can be found here.
