About Mynydd Tal-y-mignedd

Set at the middle of the Nantlle Ridge in Snowdonia, Mynydd Tal-y-mignedd is a subsidiary summit of Trum y Ddysgl. A large stone obelisk raised for Queen Victoria's Diamond Jubilee stands on top, an unmistakable marker on the skyline.

A sharp arete runs back to Trum y Ddysgl, while eastwards along the ridge a col leads on to Craig Cwm Silyn.

Which hill this one belongs to

Mynydd Tal-y-mignedd is not counted as an independent hill in its own right. In prominence terms it belongs to Trum y Ddysgl (710 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 601 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.
