About Great Rhos
Great Rhos is the highest point of Radnor Forest, the upland block north of New Radnor in mid Wales. It is the county top of old Radnorshire and stands with no higher hill near it. Black Mixen, 1.5 km east, carries a tall mast you can see from much of the area.
The usual approach starts in New Radnor and climbs past the waterfall at Water-break-its-neck, then follows forestry tracks and open moor onto the plateau. The top is a wide, gentle dome of heather and peat, so finding the highest point in mist needs care.
It is a Hewitt, a Nuttall and a Marilyn, with 379 m of prominence.
