Rhos Fawr or Great Rhos is a mountain summit in the Radnor Forest (Mid Wales), a rather isolated dome of hills to the north of the village of New Radnor. The local rocks are sedimentary shales and mudstones with some Silurian limestone. With a height of 660 metres (2,170 ft), it is the highest point in the Radnor Forest and the historic county top of Radnorshire. The summit is located on a broad heathery plateau, which is separated from Black Mixen: the eastern plateau summit, by the cwm of Harvey Dingle. To the west is Drygarn Fawr and Gorllwyn, to the northwest Plynlimon, to the north Beacon Hill and the Clun Forest (Shropshire), and to the south the Black Mountains. There is a prominent trig point at the summit, and a very useful landmark for walkers on the broad and featureless summit plateau.

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.

While I was planning my route out, I noticed on one of the ordnance maps online that there is a hill called Llanfair Hill on Offa's Dyke Path. It measures at 430m high, which is somewhere I really wanted to go and see for myself. On the day of the walk, I eventually arrived at the trig point located in a field right next to a metal fence. Llanfair Hill does offer gorgeous views of the Welsh valleys in the distance if you are planning on going walking on a clear day, just like I did.
