Y Llethr

About Y Llethr

Y Llethr is the highest mountain of the Rhinogydd in north Wales. The top is flat and grassy with only a small cairn, which suits the character of the southern flanks rather more than the rugged ground on the northern approach.

Diffwys lies to the south and Y Garn to the south-east, with Rhinog Fach to the north and the hill of Moelfre to the west. Approaches from the west start in Cwm Nantcol, either directly or by way of Bwlch Drws Ardudwy and over Rhinog Fach.

Finding the summit

The recorded summit point is ground near slight bend in wall. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

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.

The Y Llethr group

5 other listed summits sit in the same prominence group, with Y Llethr as the independent hill at its head.

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.
