Before I tell you about the most amazing views on top of Cwm-Sanaham Hill, I want to explain about how I got to the trig point so that you can follow what I did. Firstly, there is a steep ascent up the hill which can be very tough, so it's best if you are prepared if you're tackling it. 
What I did was that I charged straight up the steep pathway to which I found myself on a very narrow ledge.  You can take your time when walking up that first section of footpath. There is even a shear drop down below, so I walked along the path slowly and carefully. Secondly came the easier part, which was when I saw the trig point straight up ahead with the path still visible to follow. 
After I went past the narrow ledge, the path was then more grassy, which made things a lot more straightforward. There was no more drops to worry about, but instead the path was more even. Eventually, I arrived at the top of the hill where the trig point was located. I was then met with the most beautiful views I had ever seen, which stretched from Knighton all the way to nearby Knucklas and the rest of the Welsh valleys. 
It was also where I had my lunch, which was quite a relief after all the hill climbing I did. Cwm-Sanaham Hill is 406m high and it's the perfect vantage point to see some of the most glorious views in that part of Wales.
