In reply to Shane1990:
Despite their decent height, the Aran range need a hard winter to come into condition. Having said that , the icefalls and easier gullies in the area are climbed at some point most winters. I've attached a page from the old Welsh Winter Climbs bible of the routes on Aran Fawddwy.
ps. Maesglasau Falls IV near Dinas Mawddwy is the local gem.
