Finding the summit
ground 5m W at SN 90684 03156 and ground by forest edge 25m NW of at SN 90674 03177 are both of similar height.
The recorded summit point is trig point. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Reaching Craig y Llyn by train
2 National Rail stations sit within 8 km of the summit — close enough to make a car-free day of it. Distances are straight lines, not walking routes.
| Station | From summit | Summit lies |
|---|---|---|
| Treherbert | 5.9 km | NW of the station |
| Ynyswen | 7.1 km | NW of the station |
Each station page lists every hill in its reach, long-distance paths from the door and a live-times link — see all stations with hills in reach. Station positions from NaPTAN (OGL v3.0).
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).

| Rhigos Community Coffee Morning | Restaurant/Cafe/Canteen | 3 out of 5 | 3.1 km · NE |
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 Craig y Llyn group
8 other listed summits sit in the same prominence group, with Craig y Llyn as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Werfa | 568 m | 88 m |
| Twyn Crugyrafan | 559 m | 33 m |
| Mynydd Caerau | 555 m | 90 m |
| Mynydd Ton | 539 m | 92 m |
| Mynydd Blaengwynfi | 528 m | 38 m |
| Mynydd Tynewydd | 518 m | 32 m |
| Hirwaun Common | 515 m | 39 m |
| Mynydd Ynyscorrwg | 502 m | 41 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.
