Image of Pen Trum-Gwr, Y Tarenau (Round Barrow(s)) by GLADMAN

I reckon I tentatively located the second barrow/cairn said to be located at SH654210266... but this, the summit monument, is the outstanding viewpoint. The third – at SH6486602603 – eluded me.

Quite a decent monument in an outstanding location. The marker cairn looks like it has been en situ for donkey’s years, let alone the footprint. The wondrous Craig-yr-Aderyn (hillforts/cairn) can be seen beyond, below western Cadair Idris.

More summit views... plus a first-class descent via superb cascades...

Obscure as you like.... the final ascent from the east is not for those with a casual interest.
