Watching the hares playing on the way back from Beinn na Gainimh (1A) was memorable. Perhaps the best day was in early June - a fast ascent of Ben Stack from the north (great route). Arkle looked so tempting across Loch Stack that plans were changed and we carried on down the southern slopes of Ben Stack, along the track to Lone and up Arkle via a quite narrow rocky ridge. Great summit views, then a traverse of scree and grass down its steep west face. The evening light on the path back to the road was unforgettable.
I'm not going up anything else in future that's not a proper hill or involves getting told off. I'd rather go through a forest or up a sea stack.
