About Garnedd Uchaf
Known as Carnedd Uchaf until 2009, Carnedd Gwenllian is a modest summit on the Carneddau ridge between Foel Fras and Foel Grach. Because it lifts only a little above the ridge line it is not always counted among the Welsh 3000s, though it does qualify as a Hewitt.
Its slopes are grassy but steep, as with the rest of the northern Carneddau, and they collect deep snow-drifts in winter blizzards; snow beds have lasted into June here. The mean annual temperature is around 4-5 degrees Celsius. On clear days the view reaches Ireland and the Isle of Man to the north, and the Berwyn range to the south.

Which hill this one belongs to
Garnedd Uchaf is not counted as an independent hill in its own right. In prominence terms it belongs to Carnedd Llewelyn (1,064 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 892 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.
