Powys is home to some fabulous walking. What the hills lack in height, they more than compensate for in green-ness and rolling-ness. This walk, between the towns of Builth Wells and Crossgates Y Groes, provides a memorable day of ambling through the beautiful countryside of mid Wales. Both start and finish can be reached by bus and are on the same railway line, but note that the railway station for both places is a little way out of town.

Regular hill walkers in Wales may recognise this name from the range in Snowdonia... 'Carnedd' means 'heap' or 'cairn', so is commonly used for hills in Wales. Keep on the bridleway and continue northwards to Castle Bank.

Down and then up again - that's the nature of this route. The two small summits of Castle Bank are easily reached, before crossing over the road and towards Gilwern Hill.

A bridleway leads on to Gilwern Hill. The countryside is starting to really look like Tellytubby land, so picturebook pretty as it is!

From Gilwern, a footpath leads over Careg-wiber Bank and joins a byway - it's possible to have a shorter day out by following this to Llandrindod Wells. But those with time to spare should take the footpath heading north from the hamlet instead.

The nature of the walk changes here, as the footpath picks up the route of the Afon Ieithon. No more climbing, just a mix of farmland, woods and riverside walking.

There are several criss-crossing footpaths between the woods and Crossgates Y Groes, but the most enjoyable route is to stick close to the river. At Crossgates Y Groes, there are buses, or Penybont station is a short walk to the east. A glorious day out in mid Wales!
