If you have ascended the indistinct lump called Caha and then go west towards Cummeenbaun you can savour 3k of one of the most remote and interesting ridges in the Cahas or anywhere in Ireland.
The southern side is much less steep than the northern however it is steeper than the equivalent side of the nearby Cusnaficulla-Knockowen ridge, which is somewhat similar.

Around 800m east of Cummeenbaun you will come to the unsung, but spectacular Droppa. What an unusual name. Paul Tempan supplied the following information about it.

"The anglicised form Droppa could come from the word 'dreapa' meaning
'climb' or 'place suitable for climbing'; it can also mean 'ledge' or
'crevice' (in a cliff). The Irish words for rock-climber 'dreapadóir' and
rock-climbing 'dreapadóireacht' come from this. This interpretation would
fit with the topography.

Regarding the Irish version, the name Struice an Iolair is found on the old
"Killarney District" map, not at this point but at a higher spot near Caha,
and Eagles Nest is given as the English version. The Killarney District map
is generally less authoritative than the later Discovery series, but in
this case it would appear to be more plausible."

Our photo shows the axe-head top and steep north side of Droppa from the east, with Cummeenbaun in the background. Linkback: https://mountainviews.ie/summit/431/comment/2246/
