17 hours, 3 summits, and legions of midges
by Geo  12 Jul 2022
Using info gleaned here I used track 4024 as a template for my walk.
I started on Sunday evening, warm and muggy, climbing Knocklettragh from the busy road to the East.
From the summit of this lovely hill, I couldn't believe I was only the 17th MV member to tick this off.
I had a hydration break, a snack, took some photos and then continued west and south around to the bog workings west of the extensive Coillte forestry.
The issue then became one of excessive numbers of tiny biting, flying things, as I was now out of the breeze, and as it approached dusk, the little blighters rose from the corrie bogs and attacked me, the sole human who made the mistake of being there at that time. Mosigard gave only very short respite, as I made camp in record time diving in to my tent and zipping out the flysheet, not before several hundred got in anyway, attached as they were to various bits of me.
After a fitful night's sleep, broken by the bleating of lambs on the hills and some sort of imagined jabberwocky snuffling about outside I was glad the morning came with a stiff breeze to keep little creatures in their hiding places.
Breakfast of boiled eggs, rice cake, maple pecan, banana and a half litre of coffee I could have walked across, I shouldered my heavy pack and slowly wended my way up the spur to make the trig on Corraun Hill in time for a ten o'clock hydration break ( with some lovely sour squirms).
Then, striking while the iron was hot, I head over to the east top.
I took the spur to the west of corrie lea, carefully descending its steep sides, happy that the recent dry weather meant I could keep my balance and footing until I reached the forest below, heading east along its boundary until I reached an easy forest ride, bringing me back to the forest Road, and hence to my car.
A tough but really rewarding walk, almost 20km long with 900m plus of ascent. I couldn't find a single human footprint the whole way, and didn't see another human for nearly 17 hours until I was on the final forest stretch where I met a few mountain bikers.
A walk to add to the bucket list if solitude and peace is what you seek, and that is without mentioning the stupendous views of a dozen or more of the surrounding mountain ranges. Linkback:
