Sue Thornton and Chloe Jackson have invited us to Pentwyn Radnorshire Wildlife Trust reserve. Pentwyn is a mixture of mostly semi-improved grassland to the south, then upland acidic grassland and rush pasture extending north, giving way to upland heath. There are some small patches of conifer plantation and native woodland, and the young River Lugg flows from Beacon Hill through with an adjacent waterfall and steep-sided little gorge (SO 1773/1774).

Turn off the B4356 opposite Llugwy Farm. Go up the lane, past a bungalow on the left. Then take the right turn up a slope where there is parking available by the green agricultural shed. Park in front of the shed on the right at the top of the drive (SO 183727).
