Up for a few days walking in Donegal, visited Moylenanav and took a look at Crockastoller away in the distance and decided to take the long trek out to it, headed towards west shoulder of Crocskakallabgh and dropped down steeply to an extremely wet boggy col riven with numerous peat hags, every step took complete concentration as the going was very wet and rough eventually reached drier ground closer to the top of Crockastoller 7km from starting point. A very remote top surrounded on all approaches by very boggy rough wet ground. Headed off in a northerly direction towards minor top Croaghacullin 435m OS sheet 6, the first km was over stony dry ground only to be followed by another km through torturous terrain where again peathags abound, steps carefully taken eventually lead to the stony top of Croaghacullin, followed by another wet 2km back to the start point. A tough very demanding 13km walk in the very wet Glendowan Mts. Linkback: https://mountainviews.ie/summit/743/comment/23391/
