Mynydd Graig Goch

About Mynydd Graig Goch

Mynydd Graig Goch, the mountain of the red rock, is the peak at the western end of the Nantlle Ridge and a subsidiary summit of Craig Cwm Silyn. It is the most westerly Welsh peak above 2,000 feet.

For many years it was left out of the lists of Welsh 2000-foot mountains because OS maps gave a spot height of 609 m. That changed in 2008, when a group of hillwalkers carried out a precise GPS survey and measured the absolute height at 609.75 m, a little over 2,000 feet.

Finding the summit

The recorded summit point is rock tor. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Get food nearby

3 places to eat or drink within 10 km of the summit, rated under the Food Hygiene Rating Scheme (Scotland runs its own Food Hygiene Information Scheme, a pass/fail equivalent).

Classifications and ratings are the local authority's own and can be coarse — this is a lead, not a guarantee of opening hours or that food is served to non-residents. Follow a name through to the official rating page to check, and confirm before you rely on it.

Which hill this one belongs to

Mynydd Graig Goch is not counted as an independent hill in its own right. In prominence terms it belongs to Craig Cwm Silyn (734 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 536 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.
