Branstree always feels like a big bulk of a fell when I'm actually at the top, yet I never really feel like I've put much effort into getting there if this is the first fell visited on a walk. As for the summit itself, this is one of those places where the cairn and in this case the trig point leave you feeling a bit short changed. If like myself you expect to find a proper built up cairn or even just a big heap of stones at the top, then I'm afraid you're out of luck on Branstree. The small collection of stones you'll find up here hardly scream out that you're at the top of anywhere.
I do appreciate that we all have different preferences as far as terrain goes but to describe places like this as dull, uninteresting, dreary or a trudge says far more about the person than the place. If you arrive with the opinion that this is a wonderfully wide open area of grassy fellside, somewhere where you can wonder at will and more often than not have the place to yourself, you might just leave with a feeling of satisfaction and not one of disappointment at the lack of rocks, crags and scree.
