About Mynydd Tarw
Mynydd Tarw is a subsidiary summit of Cadair Berwyn in north-east Wales, sitting on the Powys–Wrexham boundary. A large shelter cairn marks the top.
The outlook is wide, taking in the lower northern and western Berwyns including Pen Bwlch Llandrillo, with Cadair Berwyn, Godor, Moel yr Ewig and Foel Wen also in sight. The hill formerly carried a subsidiary top, Rhos, which has since been deleted from the Nuttall list.

Finding the summit
ground beneath windshelter might be tumulus.
The recorded summit point is windshelter. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Which hill this one belongs to
Mynydd Tarw is not counted as an independent hill in its own right. In prominence terms it belongs to Cadair Berwyn (832 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 635 m.
Grouping is by prominence alone: a summit belongs to the nearest higher Marilyn it connects to without a deeper intervening col. Over a large massif that can gather hills no one would walk in a single day, and which few would describe as parts of the same mountain — it is a measure of independence, not a suggested route.
