Thanks very much Sunset tripper, prog99 and iain_atkinson_1986 - much appreciated!
That is all good food for thought. We are a few friends staying in Kintail for a week next April, and we plan to do Sgritheall on the best weather day that we get because of its views.
In an ideal world, neither scree nor scrambling among trees would be my group's preference, but I think we might need to put up with a bit of both. If we are lucky with the weather, the views will be well worth it.
Approaches from other directions look really interesting, it seems like a great hill from every direction. I also like the look of Coire Min and its lochan. But I think those options are for me to do on a solo walk sometime.
Much appreciated
Tim
