About An Caisteal
An Caisteal takes its name from the Gaelic for "the castle". It lies south of Crianlarich in the Breadalbane hills, within the Loch Lomond and The Trossachs National Park, and just clears 995 m to qualify as a Munro.

The An Caisteal group
2 other listed summits sit in the same prominence group, with An Caisteal as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Beinn a' Chroin | 941 m | 137 m |
| Beinn a' Chroin East Top | 940 m | 63 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.
