Rhos Fawr
Rhos Fawr or Great Rhos is a mountain summit in the Radnor Forest, 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, 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, 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.
