[RWD version 1 ] It had been a fair while since I'd indulged in a bit of summiteering with Indy the Wonderhound, so after we'd visited Bleck Cra in his new Fermanagh lodgings (and plundered his biscuit supply) we had a brief shlep up an outlier of the outliers of the Bluestacks: Altnapaste.
Essaying the task as per Wildcat's comment and Harry's summary, we dandered along the track to the plantation before climbing up its right hand side. One fence was easily crossed in the upper reaches of the climb (it's 20kg of Indy that needs lifting, so I like my fences to be waist rather than chest height), and the whole slope is agreeably rather than annoyingly rough.
It's a pleasant summit with wide views to the east and an impressive build up of the higher summits to the west and south.
Back the same way.
