About Aran Benllyn
Aran Benllyn is a subsidiary top of Aran Fawddwy and the second highest summit in the Aran range of southern Snowdonia. It anchors the northern end of the main Aran ridge, rising from the southern shore of Llyn Tegid (Bala Lake), with Erw y Ddafad-ddu lying between it and Aran Fawddwy.
The top carries a few rocky outcrops and a small cairn. Llyn Tegid lies to the north, Foel y Geifr east, Erw y Ddafad-ddu south and Rhobell Fawr with Cadair Idris to the west. Two lakes sit close by to the north-east, Llyn Lliwbran and the smaller Llyn Pen Aran.

Finding the summit
rock is 0.5m higher than ground by cairn (SH 86721 24313).
The recorded summit point is rock 35m S of cairn. That distinction matters on broad or flat tops, where the obvious cairn is not always the true high point.

Which hill this one belongs to
Aran Benllyn is not counted as an independent hill in its own right. In prominence terms it belongs to Aran Fawddwy (906 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 835 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.
