A long time ago - I think about 1996, when I was uninterested in going up hills, I was taken away with a bunch of guys from work and we did 2 hills near Tyndrum. In September 2012, when I got interested in going up things, I was sure that these must've been Oss & Dubhchraig and added them to my "tick list". Only decided to go up them "again" today because I was with Allison for her first walk in a couple months and she'd not done them. Wanted to go somewhere fairly close to home today too, as had a birthday party to get to in the evening. So got ready without much excitement, knowing that 1- I wasn't going to add to my number of hills and 2- we were unlikely to get much of a view. However, a walk's a walk and there's always something good to come out of them. On this occasion the good thing was the realisation that no way had I done these two before and it must've been Lui and A'Chleibh that was walked all these years ago - I distinctly remember the hills being linked by a saddle. So it was just as well I went along!
Got up to Dalrigh about 9 and found several other walkers arriving at the same time.

Weather was cloudy along the tops of the hills north of Crianlarich but I had a little optimism that it might lift (oops - wrong!). Followed the WH path over the decrepit bridge (dog took a bit of persuasion and a firm hand on the collar to go over that!) and into the trees.

The ground wasn't frozen, so the bogs were lying in wait - only went up to my knees once

There was virtually no wind and it got warm walking through the trees,

and this continued when we finally emerged onto the moor, following Allt Coire Dubhchraig with some pretty waterfalls and the inevitable patches of bog.

Through the hole in the fence with the white poly bag tied as a marker and up the hillside, following another couple of walkers a few hundred yards ahead. Started to get some snow at about 750m which meant there was a nice trail of steps to follow when the clag level was reached - no view today

The going got a little steeper, and poor Allison was feeling the lack of walking in the last 2 months. Reached the wee cairn signing the left turn up to Dubhchraig and met a couple of lads coming down, one of whom I'd met on Beinn a'Chochuill and who recognised the day-glo dog.

Soon got along to the cairn - the temperature had dropped significantly in the last 100m elevation and we stopped to put another layer on as well as snap a summit shot. By this time several other walkers had reached the top - felt positively busy today after all the recent hills with no-one else around.
Summit - Dubhchraig by

Decided to press on towards Ben Oss before stopping for some food - it was about 11.30 now and there was still a long way to go. Had to take care to go in the right direction towards Oss in the mist - spotted the wee lochans to our right, so knew we were thereabouts. Headed round the side of the hill and a steep descent to Bealach Buidhe, losing rather more height than we would have liked!

After the bealach there was another quite steep bit up towards Oss - I went off at a fair pace, leaving Allison to follow - the trail was easy enough to see with all the footprints, but the clag had reduced visibility considerably. I sat on a flat rock on the 941 plateau and waited for what seemed like ages for her to catch up - started to get a little worried when she didn't appear and although I walked over to the edge of the rise I couldn't see hide nor hair of her - realised it wasn't such a smart idea to blaze away off in the fog, even when there was an easy track to follow. Began to wonder if she'd taken another path and gone round behind me and thought of going on to the summit in case she was there, but that didn't seem sensible either. However, at that point she pulled into view and with much relief we decided to have some food and a coffee to recharge.
The final section from the 941 plateau to the 1029 top was interrupted with another small saddle with a further descent of almost 100m which wasn't a delightful surprise

There was a patch of snow going up the final slope and this combined with the mist to make everything white and silent.

By this time it really was getting late having taken almost 5 hours to get here, and I was worried we were going to run out of daylight as we had 8.5km to get back to the car.

Care was needed getting down the steeper sections of Ben Oss and up to the NW aspect of Dubhchraig.

Once we were heading down Dubhchraig there were a couple of smooth snowy patcxhes which made for a nice slide down!

Walking was easier on the reverse direction and we made good time, with good views over to the hills in the North.

Saw the couple before us taking the alt route back to the car which involved fording Allt Gleann Auchreoch about 300m south of the rickety bridge, but we elected to brave the missing planks again, although the dog was not particularly pleased
Not again!! by

The other route seemed quicker as they made the car park well in advance of us. Anyway, 2.5 hours on the return leg and there was still light when we made the car park . Pleasant drive back down Loch Lomond in the dusk and got home just in time to go out again to a party - without even the time to get changed!
